Valentine’s Day isn’t just about heart-shaped cards and candy—it’s also an excellent opportunity to ignite a love of science, technology, engineering, and math (STEM) in kids! Whether your young learners are at summer camp or exploring STEM at home, these fun and festive activities are perfect for combining creativity with curiosity.

 

Build Candy Heart Structures

Put those colorful conversation hearts to good use! Provide kids with toothpicks and candy hearts to create towers, bridges, or other structures. Encourage them to experiment with shapes and stability while learning about engineering concepts.

Challenge Idea: Which structure can hold the most weight? Add small objects like coins to test their creations.
 

Fizzing Love Potions

Turn Valentine’s Day into a mini chemistry lab! Combine baking soda and vinegar with a touch of food coloring and glitter to create “love potions.” Kids will be fascinated by the fizzy reaction and can experiment by altering the ingredient ratios.

STEM Takeaway: Discuss chemical reactions and why combining an acid (vinegar) with a base (baking soda) causes fizzing.

 

Floating Heart Experiment

Cut out heart shapes from cardstock and draw on them with washable markers. Place them in a shallow dish of water and watch as the drawings float and move around. Kids will be mesmerized by the simple magic!

Why It Works: Discuss how water interacts with the marker’s ink and the properties of surface tension.
 

Valentine’s Day Slime

Mix up a batch of Valentine-themed slime using glue, contact lens solution, and glitter. Add red or pink dye and heart-shaped confetti for a festive twist. Kids will love getting hands-on with this gooey, fun STEM activity. For more slime fun, check out the Fun Ways To Make And Use Slime blog post.

Exploration Idea: Experiment with the slime’s consistency by adjusting the ingredient proportions.

Valentine’s Day STEM activities are a fantastic way to celebrate love while fostering a passion for science and creativity. Whether building, experimenting, or coding, these hands-on projects will keep kids engaged and inspired.
