Preschool science is all about exploring the world through the senses! Young kids learn best when they can see it fizz, feel it squish, smell it bubble, or even taste it. That’s why sensory science activities are perfect for preschoolers—they combine real science with meaningful, hands-on play.
Easy Sensory Science Activities
In this post, you’ll find our favorite science activities for preschool that are full of texture, color, sound, scent, and even flavor! Whether you’re at home or in the classroom, these sensory-rich experiments will engage your kids’ natural curiosity and support early science skills.

About the 5 Senses
Sensory science revolves around the five senses: sight, smell, hearing, taste, and touch. These senses help young kids understand and interact with the world around them. By incorporating sensory input into science activities, kids can explore concepts more deeply through observation, prediction, and discovery.
Below, we’ve grouped activities by the main sense they engage—though many involve multiple senses at once!
🔎 Explore more specific 5 senses activities here.
Science You Can Feel: Tactile Sensory Activities
These activities are all about texture! From squishy to icy to stretchy, kids will love getting hands-on with experiments they can really feel.
- Oobleck: Is it a liquid or a solid? Mix cornstarch and water and let kids explore this non-Newtonian fluid.
- Flower Ice Play: Freeze small flowers in ice cube trays or containers
- Ice Excavation: Freeze small objects in blocks of ice for kids to melt, chip, or salt away.
- What Absorbs Water?: Use different materials to test and compare absorption through touch and observation.
- Soap Foam Play: Mix dish soap, water, and a bit of food coloring to create bubbly foam. Let kids scoop, squeeze, and swirl.
- Texture Scavenger Hunt: Go on a hunt indoors or outdoors for rough, smooth, soft, and bumpy items. Discuss what makes each texture unique.
- Sinking and Floating with Hands-On Materials: Let kids hold and test different objects in water to explore what sinks or floats.
- Guess the Object Game: Place small objects in a bag and let kids reach in to describe what they feel before guessing what it is.
- Bouncing Bubbles: Catch and bounce bubbles without popping them.
Science You Can Smell
These experiments engage the nose! Scents can evoke strong reactions and memories, making them a powerful learning tool for young kids.
- Kool Aid Playdough: Vibrant, scented, and safe for preschool hands. A great way to engage multiple senses.
- Spice Paint: Mix paint with cinnamon, nutmeg, or cloves to engage the sense of smell while creating.
- Lemon Volcano: The zesty smell of lemons meets the fizz of a baking soda reaction.
- Chickpea Foam (Aquafaba): A fluffy, taste-safe foam that smells slightly sweet and earthy.
- Herb and Flower Scents Station: Set up small containers with rosemary, lavender, mint, or rose petals for sniffing and comparing.
Science You Can See
Visual science experiments show dramatic color changes, light, and movement—perfect for making scientific ideas visible to young eyes.
- Melting Crayons: Explore how heat changes a solid into a liquid by melting old crayons into new shapes.
- Baking Soda Volcano: Classic eruption fun with endless variations (apple, lemon, watermelon, LEGO, pumpkin). Explore more baking soda and vinegar experiments here.
- Shadow Science: Use flashlights, hands, and paper cutouts to explore how light and shadow interact.
- Skittles Rainbow: Arrange Skittles in a circle on a plate and add warm water—watch the colors spread!
- Magic Milk: Add food coloring and dish soap to milk for a swirling color explosion that’s mesmerizing to watch.
- Grow a Rainbow: Use a paper towel, markers, and water to watch color travel and mix through capillary action.
- Lava Lamp: Mix oil, water, food coloring, and Alka-Seltzer to create bubbling blobs of color in a jar.
- Color Changing Flowers: Watch how white flowers absorb colored water to learn about capillary action.
- Seed Jar: Watch how seeds sprout and grow roots and stems in a clear jar.
Science You Can Hear
These sound-based science ideas engage little ears and teach concepts like vibration, pitch, and volume through playful experimentation.
- Water Xylophone: A visual and auditory experiment that explores sound waves through water levels.
- Listening Walk: Go outside and have kids identify and record the sounds they hear (birds, leaves, cars).
- Sound Shakers: Fill containers with rice, beans, and pasta to compare sounds and explore pitch and volume.
Science You Can Taste
Taste-safe science activities help kids explore chemical reactions and physical changes with a delicious twist.
- Apple Taste Test: Use red, green, and yellow apples to explore taste differences and preferences.
- Edible Slime: From chocolate pudding to marshmallow slime, explore texture and taste together.
- Butter in a Jar: Shake heavy cream and watch it transform into butter—then taste the results!
- Fizzing Lemonade: Mix lemon juice and baking soda for a fizzy, drinkable reaction.
- Ice Cream in a Bag: Explore freezing and phase changes while making a tasty frozen treat.
- Bread in a Bag: Learn about chemical reactions like yeast fermentation.
Tips for Making Sensory Science Easy
- Use trays or bins to contain mess and make cleanup easier.
- Encourage kids to describe what they feel, smell, see, and hear.
- Offer choices to support independence and creativity.
- Repeat activities with seasonal or themed twists for added interest.
