STEM Activities for Kids: 10 Simple Science Experiments That Actually Work

Look, I’ll be real with you—when I first heard about “STEM activities,” I pictured complicated science experiments that would end with me scrubbing mystery goo off the ceiling while my toddler had already moved on to emptying the Tupperware drawer. Again.

But here’s what I’ve discovered: STEM (Science, Technology, Engineering, and Math) doesn’t have to mean elaborate setups or expensive kits gathering dust in your closet.

Some of the best learning happens with stuff you probably already have lying around, and—plot twist—kids actually think these activities are fun. Like, genuinely fun, not just “Mom says it’s educational” fun.

Whether you’re homeschooling, looking for screen-free weekend activities, or desperately need something to occupy your kiddos on a rainy Tuesday afternoon, these 10 STEM activities have been parent-tested and kid-approved.

Most take less than 10 minutes to set up, and I promise none of them require a science degree to explain. Let’s jump in!

1. Build-Your-Own Volcano (The Classic That Never Gets Old)

Image Prompt: A child around 5-6 years old kneels on a protected outdoor patio surface, eyes wide with anticipation as a homemade volcano (made from clay or playdough around a small plastic bottle) begins to erupt with red-tinted foam. The child is wearing old clothes and has their hands pressed to their cheeks in delighted surprise. Science supplies are visible nearby—baking soda box, vinegar bottle, food coloring. A parent crouches beside them with a phone camera ready to capture the moment. Bright afternoon sunlight, genuine excitement, that perfect “science is magic” expression. The setup looks achievable and fun, not intimidating.

How to Set This Up

Materials needed:

• Empty plastic water bottle (16 oz works great)
• Baking soda (about 2-3 tablespoons)
• White vinegar (1 cup)
• Red or orange food coloring
• Dish soap (1 squirt—makes the eruption foamier)
• Clay, playdough, or even dirt to build the “mountain” around the bottle
• Large tray or do this outside to contain the mess

Step-by-step instructions:

• Place the bottle on your tray or directly on grass/pavement outside
• Let your child mold clay or playdough around the bottle to create a mountain shape (leave the opening exposed!)
• Mix food coloring and dish soap into the vinegar in a separate container
• Put baking soda inside the bottle opening
• When ready for eruption, pour the vinegar mixture into the bottle and step back!

Age appropriateness: 3-10 years (younger kids can help build and watch; older kids can measure and pour)

Time commitment: 15-20 minutes setup and play, 5 minutes cleanup

Mess level: Medium-high (but it’s mostly just fizzy liquid that rinses away easily)

Developmental benefits: Chemical reaction observation, cause-and-effect understanding, prediction skills, vocabulary building (eruption, lava, volcano), patience while building

Safety considerations: Adult should handle the vinegar for kids under 5; the “lava” is safe but might sting eyes, so keep little hands from rubbing faces

Activity variations:

• Add glitter to the vinegar for “magical lava”
• Try different ratios to see which creates the biggest eruption
• Build multiple small volcanoes and race them
• Freeze the vinegar mixture beforehand for a slow-melt eruption

Cost-saving tip: Skip the fancy kits—baking soda and vinegar cost under $5 total

Cleanup strategy: Hose it down outside, or wipe up with damp paper towels if indoors (the reaction neutralizes itself, leaving just salty water)

2. Sink or Float Science Experiment

Image Prompt: A preschooler around 3-4 years old stands on a sturdy step stool at a kitchen sink or large plastic bin filled with water, carefully placing objects one by one into the water while watching intently to see what happens. The scene shows a variety of household items lined up—a toy car, wooden spoon, plastic ball, rock, sponge, etc. The child has a look of focused curiosity, and there’s a simple two-column chart on the counter (drawn on paper) with “SINK” and “FLOAT” headers. Water droplets on the counter, rolled-up sleeves, afternoon kitchen lighting. The parent’s hand is visible steadying the step stool. Exploratory learning in action.

How to Set This Up

Materials needed:

• Large bin, bathtub, or sink filled with water
• 10-15 objects of varying weights and materials: toys, fruit, utensils, rocks, corks, sponges, plastic containers, etc.
• Towel for inevitable splashing
• Optional: paper and markers to create a prediction chart

Step-by-step instructions:

• Fill your container with water (room temperature works fine)
• Gather objects from around the house—encourage your child to pick things they’re curious about
• Before testing each item, ask: “Do you think this will sink or float?”
• Let them place each object gently in the water and observe
• Sort items into “sink” and “float” piles afterward
• Talk about why certain things behaved as they did (heavy/light, hollow/solid)

Age appropriateness: 2-8 years (toddlers love the simple action; older kids can grasp the science behind it)

Time commitment: 20-30 minutes of engaged play

Mess level: Medium (it’s just water, but there will be splashing—do it near a sink or outside if weather permits)

Developmental benefits: Scientific method introduction (predict, test, observe, conclude), categorization skills, vocabulary expansion (dense, buoyant, hollow), fine motor practice

Safety considerations: Supervise near water always; avoid small items that could be choking hazards for kids under 3

Activity variations:

• Test the same object in saltwater vs. freshwater (dissolve salt in one container)
• Try aluminum foil shaped different ways (flat sheet vs. crumpled ball vs. boat shape)
• Use a stopwatch to time how long it takes different objects to sink
• Add dish soap and see if it changes anything (spoiler: it doesn’t much, but kids love bubbles)

Cost-saving tip: This one’s literally free—you already own everything you need

Parent sanity-saving tip: Do this right before bath time and let them splash away—everyone’s getting wet anyway!

3. Rainbow Walking Water Experiment

Image Prompt: Three clear plastic cups sit in a row on a kitchen counter, filled with water tinted red, yellow, and blue. Paper towels are folded into strips and draped between the cups, already showing colorful water creeping up the paper towel fibers. A child around 6-7 years old leans in close, examining the color mixing happening before their eyes with a look of wonder. The parent is beside them, pointing to where yellow and blue are creating green. Bright natural window light illuminates the setup, making the colors vivid. A notebook lies nearby with crayon drawings attempting to predict what will happen. Pure discovery moment.

How to Set This Up

Materials needed:

• 6 clear plastic cups or jars
• Water
• Food coloring (red, yellow, blue)
• Paper towels
• Patience (this takes 1-2 hours to see full results)

Step-by-step instructions:

• Arrange 6 cups in a circle or line
• Fill alternating cups with water (so 3 cups have water, 3 are empty)
• Add food coloring to the filled cups: one red, one yellow, one blue
• Fold paper towels lengthwise into strips (about 2 inches wide)
• Place one end of a paper towel strip in a colored cup and the other end in an empty cup beside it
• Continue around the circle so each empty cup has two paper towel strips leading into it from different colored cups
• Wait and watch! Check back every 20-30 minutes

Age appropriateness: 4-10 years (younger kids need help with setup but love watching; older kids can do it independently)

Time commitment: 10 minutes setup, then check-ins over 1-2 hours

Mess level: Low (just don’t knock over the cups)

Developmental benefits: Capillary action observation (water traveling upward against gravity), color mixing discovery, hypothesis formation (“What color will yellow + red make?”), patience and delayed gratification

Safety considerations: Food coloring can stain, so use on protected surfaces; keep away from toddlers who might drink it

Activity variations:

• Try different paper products (coffee filters, newspaper, tissue paper) and compare speed
• Use different water temperatures to see if it affects travel time
• Add more or fewer drops of food coloring to create different shades
• Set up two experiments side by side—one with cold water, one with warm

Cost-saving alternative: Use leftover Easter egg dye instead of food coloring

Cleanup strategy: The paper towels can go straight in the trash; rinse cups immediately so food coloring doesn’t stain

4. Simple Circuit With Playdough

Image Prompt: A child around 7-8 years old sits at a cleared dining table with homemade playdough, a small battery pack (holding 2 AA batteries), and an LED light. Their face shows concentration as they successfully make the LED light up by connecting it through two separate playdough blobs. Wire leads extend from the battery to the playdough. The child is giving a triumphant smile as the light glows. Additional playdough colors and more LEDs are nearby, suggesting they’re about to experiment further. Warm indoor lighting, parents visible in the background looking impressed. The setup looks accessible and not intimidating—no complicated wiring visible.

How to Set This Up

Materials needed:

• Homemade or store-bought playdough (2 colors work best—1 conducting, 1 insulating)
• Battery holder with 2 AA batteries
• LED lights (get these cheap online or from a hardware store)
• Wires with alligator clips (optional but helpful)
• Recipe for homemade conducting playdough (mix 1 cup flour, 1/4 cup salt, 1 cup water, food coloring—the salt makes it conductive!)
• Recipe for insulating playdough (mix 1 cup flour, 1/2 cup sugar, 3 tbsp oil, 1/2 cup water—no salt!)

Step-by-step instructions:

• Make two playdough batches (one salty/conducting, one not) or buy pre-made and add salt to one batch
• Roll each dough type into a ball, keeping them separate on the table
• Insert one wire from the battery pack into the conducting playdough
• Insert the long LED leg into that same playdough ball
• Insert the short LED leg into the insulating playdough ball (or a second conducting ball)
• Connect the second battery wire to that second playdough ball
• Watch the LED light up! If it doesn’t, flip the LED around

Age appropriateness: 6-12 years (younger kids can participate with close supervision)

Time commitment: 30 minutes to make playdough (if homemade) + 20-30 minutes experimenting

Mess level: Medium (playdough crumbs and potential food coloring on hands)

Developmental benefits: Introduction to electrical circuits, conductivity vs. insulation concepts, problem-solving (why isn’t it working?), creative thinking about electricity

Safety considerations: LEDs get slightly warm but not hot; batteries are safe; don’t let kids put playdough near mouths if they still taste everything

Activity variations:

• Create a playdough “creature” with LED eyes
• Build a circuit maze where electricity has to travel through conducting dough paths
• Use multiple LEDs to make patterns or letters
• Test other household items to see if they conduct (aluminum foil does; plastic doesn’t)

Cost-saving tip: Basic LED packs cost about $5 for 50 lights on Amazon; playdough is pennies to make

Troubleshooting tip: If the LED doesn’t light, try flipping it around—they only work in one direction!

5. Build Structures With Marshmallows and Toothpicks

Image Prompt: Two siblings, ages 5 and 8, work together at a craft table covered with a silicone mat. Before them is an impressive (if wobbly) structure made entirely of mini marshmallows and toothpicks—it’s attempting to be a tower but has a distinct lean. Both kids have marshmallow-sticky fingers and are laughing as they try to add “just one more level” before it collapses. A bag of mini marshmallows sits open nearby, along with a box of toothpicks. The older child is demonstrating how to create a triangle shape for stability. Afternoon light, joyful chaos, engineering in progress. A few failed attempts lie toppled on the table.

How to Set This Up

Materials needed:

• Mini marshmallows (2-3 bags depending on ambition level)
• Toothpicks (one regular box has hundreds)
• Flat surface
• Optional: printed pictures of basic structures (pyramids, cubes, bridges) for inspiration
• Optional: gumdrops or cheese cubes as heavier alternatives

Step-by-step instructions:

• Dump out the marshmallows and toothpicks (yes, just dump them—organized STEM is an oxymoron with kids)
• Show your child how to push a toothpick into a marshmallow to connect pieces
• Start with basic shapes: triangle, square, cube
• Challenge them to build the tallest tower, the strongest bridge, or a specific structure
• Test stability by gently pressing or placing a light object on top
• Rebuild when things inevitably collapse (that’s engineering, baby!)

Age appropriateness: 3-10 years (preschoolers make simple shapes; older kids attempt complex structures)

Time commitment: 30-60 minutes (kids get surprisingly absorbed in this)

Mess level: Low (just sticky fingers and a few rogue marshmallows under the couch)

Developmental benefits: Spatial reasoning, geometry basics (recognizing 2D and 3D shapes), fine motor skill refinement, trial-and-error persistence, introduction to structural engineering concepts, teamwork if done with siblings/friends

Safety considerations: Toothpicks have sharp ends—supervise young kids; don’t let them run around with toothpicks in hand

Activity variations:

• Give specific challenges: “Build a bridge that can hold this toy car”
• Use a timer and see who can build the tallest structure in 10 minutes
• Create marshmallow “molecules” to learn about atoms and bonds
• Build structures based on real landmarks (Eiffel Tower, pyramids)

Cost-saving tip: Mini marshmallows are cheaper at discount stores; reuse toothpicks for multiple rounds

Parent reality check: Some marshmallows will definitely get eaten—this is inevitable and acceptable

6. DIY Magnifying Science Exploration

Image Prompt: A child around 4-5 years old lies on their stomach on a sunny backyard lawn, holding a large magnifying glass close to the grass, examining tiny insects and plants with intense focus. Their face shows pure wonder and discovery. Around them are collected items for examination: leaves, flowers, rocks, a feather. A small notebook with rough crayon drawings of “discoveries” lies open nearby. The parent’s shadow falls across the scene, indicating supervision. Golden hour lighting, curious exploration, that magical moment when the ordinary becomes extraordinary through magnification.

How to Set This Up

Materials needed:

• Magnifying glass (get a sturdy one designed for kids—around $8-12)
• Collection container (bucket, basket, or egg carton)
• Items to examine: leaves, flowers, insects (if your kiddo is brave), rocks, sand, fabric, food items (salt crystals, sugar, orange peel)
• Optional: phone or camera to document discoveries
• Optional: journal for drawing observations

Step-by-step instructions:

• Go on a “collection walk” around your yard or park
• Gather interesting items (remind kids to be gentle with living things)
• Find a comfortable spot to examine your collection
• Look at each item through the magnifying glass
• Talk about what you notice: textures, patterns, colors, tiny details invisible to the naked eye
• Take photos through the magnifying glass if you can (actually super cool)
• Draw or describe favorite discoveries

Age appropriateness: 3-10 years (even toddlers are fascinated by magnification)

Time commitment: 30-60 minutes depending on interest level

Mess level: Low (unless they dig in dirt, then medium)

Developmental benefits: Observation skills, attention to detail, vocabulary expansion (describing what they see), nature appreciation, patience and focus, early scientific recording

Safety considerations: Don’t let kids use magnifying glasses to focus sunlight (fire hazard and eye risk); supervise around insects in case of allergies

Activity variations:

• Create a “field guide” of everything discovered
• Compare the same type of item from different locations (leaves from different trees)
• Bring items indoors and examine them under different lighting
• Use the magnifying glass during cooking to look at salt, sugar, flour, herbs

Cost-saving tip: Dollar stores often have decent magnifying glasses for $1-3

Extension idea: Graduate to a cheap digital microscope ($30-50) if your child loves this activity—mind. blown.

7. Kitchen Chemistry: Baking Soda and Vinegar Reactions

Image Prompt: A child around 6 years old stands at a kitchen counter wearing a too-big “lab coat” (actually just an adult’s old white button-up shirt), safety goggles pushed up on their head, with several small dishes arranged before them. Each dish has a different substance—baking soda, glitter, food coloring, dish soap. They’re using a medicine dropper to add vinegar to one dish, which is fizzing enthusiastically. Their expression is one of delighted concentration. The parent stands nearby with a spray bottle of water for cleanup. Science supplies are organized in muffin tins. Bright kitchen lighting, contained chaos, serious young scientist vibes.

How to Set This Up

Materials needed:

• Baking soda (one box)
• White vinegar (one bottle)
• Muffin tin, small dishes, or ice cube tray
• Medicine droppers or small measuring cups
• Optional add-ins: food coloring, glitter, dish soap, watercolor paint
• Tray or baking sheet to contain the mess
• Old shirt or smock for your little scientist

Step-by-step instructions:

• Put your work surface inside a large tray or baking sheet
• Scoop baking soda into each compartment of your muffin tin (about 1-2 tablespoons each)
• Add different extras to each: a few drops of food coloring in some, glitter in others, a squirt of dish soap, etc.
• Give your child vinegar in a small cup with a dropper or measuring spoon
• Let them “experiment” by dropping vinegar onto different combinations
• Watch the fizzy reactions—each one behaves slightly differently!
• Discuss what they observe: which fizzes most? Longest? Creates the most foam?

Age appropriateness: 3-8 years (toddlers love the fizzing; older kids can hypothesize and record results)

Time commitment: 20-30 minutes of bubbling fun

Mess level: Medium-high (it fizzes over, glitter goes everywhere if you use it, food coloring can stain)

Developmental benefits: Chemical reaction observation, cause-and-effect understanding, early hypothesis testing (“What if I add MORE vinegar?”), sensory exploration, color mixing experimentation

Safety considerations: Vinegar can sting eyes—remind kids not to touch their faces; glitter is slippery when wet; do this in a well-ventilated area (vinegar smell!)

Activity variations:

• Freeze vinegar in ice cube trays and watch the slow-release reaction
• Hide small toys in baking soda “snow” and excavate with vinegar droppers
• Make baking soda “paint” (mix with water until paste-like) and paint it on paper, then spray with vinegar in a spray bottle for reactive art
• Create different “potions” with various ratios and additives

Cost-saving tip: This entire activity costs under $5 if you already have the containers

Cleanup strategy: The reaction neutralizes itself into basically salty water—wipe with a damp cloth and call it done

8. Shadow Science and Tracing

Image Prompt: Two children, ages 4 and 7, sit on a sunny driveway with colorful sidewalk chalk scattered around them. The younger child is tracing the shadow of their hand on the pavement while the older sibling traces the shadow of a toy dinosaur. A parent’s shadow is visible, holding a large cardboard cutout to create interesting shadow shapes. Various objects are arranged nearby waiting to be traced—toys, leaves, sports equipment. The shadows are crisp and defined in the strong afternoon sunlight. Both kids are smiling, engaged in discovering how shadows change size when you move objects closer or farther from the ground. Pure creative exploration on a beautiful day.

How to Set This Up

Materials needed:

• Sunny day (nonnegotiable, unfortunately)
• Large sheets of paper, sidewalk chalk, or sand to draw in
• Various objects: toys, household items, cutouts, their own hands and bodies
• Optional: flashlight for indoor shadow exploration
• Optional: white sheet hung as a shadow puppet screen

Step-by-step instructions:

• Choose your sunny spot (driveway, patio, sidewalk, large paper on grass)
• Start simple: have your child trace their own hand’s shadow with chalk
• Experiment with different objects and trace their shadows
• Notice how shadows change size when you move the object up or down
• Try making shadow puppets with hands
• If indoors, use a flashlight or lamp to create shadows on the wall—kids can trace these on paper taped to the wall
• Return at different times of day to see how shadow length and direction change

Age appropriateness: 3-10 years (even toddlers can trace simple shapes; older kids grasp the science concepts)

Time commitment: 30-45 minutes

Mess level: Low outdoors (just chalk dust); medium indoors if using markers

Developmental benefits: Understanding light and shadows, spatial awareness, observation of sun movement throughout the day, early physics concepts, hand-eye coordination, creative art-making

Safety considerations: Keep sun safety in mind—hats and sunscreen if doing this activity for extended periods

Activity variations:

• Trace a child’s shadow at morning, noon, and sunset to compare
• Create a shadow puppet show with flashlight and cutout characters
• Play shadow tag in the yard
• Measure shadow lengths and graph them hourly
• Make shadow art by arranging objects to create pictures with their combined shadows

Cost-saving tip: Free! You literally just need sun (or a flashlight)

Extension idea: Take photos of shadow art throughout the day and make a “shadow story” book together

9. Ramp Racing: Physics With Toy Cars

Image Prompt: A child around 5-6 years old kneels on a carpeted living room floor next to an elaborate ramp system they’ve built using cardboard, books, and couch cushions. They’re releasing toy cars down the ramp one at a time, watching intently as each car zooms down and across the floor. A parent crouches nearby with a phone timer, timing each car’s journey. Several toy cars are lined up waiting for their turn—different sizes, weights, and styles. Books of varying thicknesses are stacked to create different ramp heights. A measuring tape stretches across the floor to see how far each car travels. The child’s face shows competitive excitement mixed with scientific curiosity. Cozy afternoon lighting, active learning happening.

How to Set This Up

Materials needed:

• Toy cars (at least 3-5 different types)
• Ramp material: cardboard, foam board, large hardcover books, or even a cutting board
• Books or blocks to prop up one end of the ramp
• Measuring tape or yarn
• Stopwatch or phone timer
• Optional: masking tape to mark landing spots
• Optional: notebook to record results

Step-by-step instructions:

• Create a ramp by propping up one end of your board/cardboard on a stack of books
• Choose a starting point on the ramp and mark it with tape
• Release one car from the starting point and measure how far it travels
• Time how long it takes to reach the bottom (or a certain point on the floor)
• Try different cars and compare results
• Change variables: make the ramp steeper or gentler, add weight to cars, use different rolling surfaces
• Let your child predict which changes will make cars go faster or farther

Age appropriateness: 3-10 years (young kids love the racing; older kids can collect data and graph results)

Time commitment: 30-60 minutes (kids LOVE this one)

Mess level: Low (unless cars crash into things—remove breakables first)

Developmental benefits: Introduction to gravity, momentum, friction concepts, variables and constants in experiments, measurement skills, prediction and hypothesis testing, data recording

Safety considerations: Make sure the ramp is stable and won’t collapse; keep ramp area clear of obstacles; supervise if using heavier objects that could hurt toes

Activity variations:

• Create obstacle courses at the bottom of the ramp
• Add cardboard tubes for cars to race through
• Compare different ramp surfaces (smooth cardboard vs. sandpaper)
• Test whether adding weight to cars makes them faster (tape pennies to the top)
• Build loop-de-loops or jumps (this requires some engineering!)

Cost-saving tip: Use items you already have—you don’t need fancy ramp kits

Parent sanity-saving tip: Designate a “finish line” so cars don’t roll under furniture and get lost forever

10. Plant Growth Observation Experiment

Image Prompt: A child around 7-8 years old sits at a sunny kitchen window ledge where several clear plastic cups sit in a row, each labeled with tape and marker. Bean plants in various stages of growth are visible through the cup sides—roots spreading downward, shoots reaching up. The child is using a ruler to measure one plant’s height while carefully writing measurements in a well-worn science journal. A watering bottle sits nearby. Sticky notes with dates mark each cup. Morning sunlight streams through the window, illuminating the plants. The child’s face shows quiet pride in nurturing these growing things. Patient, long-term science in action. A calendar on the wall has plant-watering days circled in green marker.

How to Set This Up

Materials needed:

• Bean seeds (lima or green beans work great—they sprout fast!)
• Clear plastic cups (so you can see root growth)
• Paper towels
• Water
• Sunny window or grow light
• Ruler
• Journal or paper for recording observations
• Optional: potting soil if you want to transfer plants eventually

Step-by-step instructions:

• Dampen paper towels and line the inside of clear cups with them
• Place 2-3 bean seeds between the paper towel and the cup side (visible from outside)
• Add a small amount of water to the bottom of the cup (about 1/4 inch)
• Place cups in a sunny window
• Check daily—keep paper towels damp but not soaking wet
• Within 5-7 days, you’ll see roots and shoots!
• Measure and record growth every few days
• Talk about what plants need: water, light, warmth
• Optional: set up multiple experiments (one in light, one in dark; one with water, one without; one warm, one cold)

Age appropriateness: 4-12 years (younger kids can help with daily care; older kids can conduct controlled experiments)

Time commitment: 5 minutes daily over 2-3 weeks

Mess level: Low (just water and some dirt if transplanting)

Developmental benefits: Life cycle understanding, responsibility and routine (daily care), observation and recording skills, patience and delayed gratification, understanding plant needs, introduction to controlled experiments

Safety considerations: Non-toxic seeds and plants only; wash hands after handling seeds

Activity variations:

• Compare growth between different seed types (beans vs. sunflower seeds)
• Test variables: one plant gets fertilizer, one doesn’t; one gets constant light, one doesn’t
• Decorate cups and create a “garden” in your window
• Read The Tiny Seed by Eric Carle alongside this experiment
• Transfer successfully sprouted beans to a garden or larger pot

Cost-saving tip: Seeds cost about $2 for a packet; everything else is likely already in your home

Parent reality check: Some seeds won’t sprout—this is actually a good lesson about trying again and not giving up

Extension idea: Start a vegetable garden together if this experiment is successful and your child shows continued interest!

Wrapping It All Up

Here’s the truth about STEM activities with kids: they don’t have to be perfect, they won’t always work as planned, and you absolutely do not need a teaching degree to make them meaningful. Some of the best learning happens when experiments “fail” and you troubleshoot together, or when your child takes an activity in a completely unexpected direction.

The volcano might not erupt as dramatically as the YouTube video showed. The marshmallow tower will collapse. Someone will drink the colored water when you turn around for two seconds (true story). And that’s all perfectly fine—because the goal here isn’t perfection. It’s curiosity. It’s your child looking at the world around them and asking “why?” and “what if?”

These 10 activities are just starting points. Let your kids modify them, combine them, or abandon them halfway through in favor of something even more interesting they discovered. Follow their interests. If they’re obsessed with dinosaurs, use toy dinosaurs in your ramp experiments. If they love everything pink, make pink volcanoes. STEM isn’t about following rigid instructions—it’s about exploring, discovering, and yes, making some messes along the way.

So grab some household items, embrace the chaos, and watch your little scientists, engineers, and mathematicians get to work. The future is in their curious, sticky-fingered hands, and it’s looking pretty bright. <3

You’ve got this, and your kids are lucky to have someone who cares enough to explore the world with them. Now go make something bubble, explode, or grow—childhood waits for no one!
