Valentine’s Day STEM Activities

January 29, 2024 by Sarah White Leave a Comment

Every holiday gives us an opportunity for new twists on STEM activities, and Valentine’s Day is no exception. Whether you want to use candy in your experiments or use other materials, this roundup should get you thinking about fun STEM things you can do for Valentine’s Day in the classroom or at home.

I love this paper hearts structure building challenge from Buggy and Buddy because it’s an engineering challenge that turns into a decoration for the classroom. Print out their template to make paper strips of different sizes to turn into hearts and stack together.

Feel Good Teaching has a fun STEM game for kids to play by filling a heart outline with the shapes of other hearts. Hearts of different sizes have different point values, and the goal is to get the highest point value to fill the space.

If you’re OK with using food in your STEM challenges, there are lots of things you can do with conversation hearts, like build a tower (Math Geek Mama) or a more complex structure (Productive Pete) or try some coding and other engineering challenges (Momgineer). The candy catapult is always a popular option, too (There’s Just One Mommy). Or you can observe what happens to candy in different liquids with this experiment from Curriculum Castle.

Challenge kids to create Valentine’s themed Lego projects with this Valentine brick challenge from 123 Homeschool 4 Me. Or challenge them to a whole bunch of STEM activities with this list of ideas from Little Bins for Little Hands. I love the cup stacking challenge, which is shown here.

I could resist sharing a recipe for Valentine’s slime, of course; this one is from There’s Just One Mommy and uses glitter glue to make it extra sparkly (though you could just add glitter to the recipe if you don’t have glitter glue handy).

Book Review: The Festival of Lights

As if Diwali weren’t colorful and fun enough, The Festival of Lights: A Lift-the-flap Diwali Celebration by Namita Moolani Mehra, illustrated by Darshika Varm, makes it even more fun to read about with flaps and things to lift and pull to see more information or details in the illustrations. 

The book is a story about a family getting ready for Diwali and what happens on the different days of the five-day celebration. There’s cleaning, shopping, crafting, food preparation and getting the home altar ready for the big day. 

It covers decorating the outside of the house with rangoli, diyas and lanterns, buying sweets to share with family and friends, the sights and scents of the mandir (home temple), getting dressed up in new fancy clothes, the story of Diwali and celebrations with relatives.  

Flaps (there are more than 140 in all) give you vocabulary words for different foods and definitions, as well as fun things like what’s inside the shopping basket or where the cat is hanging out. They also help illuminate the story of Diwali, which is the triumph of good over evil as Lord Ram defeated the demon Ravana to save his wife, Sita. 

This pretty and colorful book helps kids understand what Diwali is and how it is celebrated, regardless of whether they practice it at home. This would be a nice book to keep in a classroom (it’s rated for kids ages 3-7) or to have at home to teach kids about Diwali even if it’s not something you celebrate. Where I live there are a lot of people from India so we are probably exposed to Diwali more than some other regions of America, but it’s a nice holiday to know about wherever you live. 

Combine with the book Diwali and check out some fun lantern crafts and printables for kids to round out your experience. 

About the book: 24 pages, hardcover, published 2025 by Wide Eyed Editions. Suggested retail prices $22.99.
