Written by I’m a bit last minute with Valentine’s Day this year. My 10-year-old is currently making a card next to me while I plan some easy activities for us tomorrow.
These Valentine STEM challenges are designed to be very easy and use only basic materials.
If you’re looking for something a bit more involved, check out my full collection of Valentine’s Day science experiments. The magic colour changing potions are my favourite!
Send a Valentine’s Message
The idea behind this Valentine’s Day STEM challenge is to create a delivery mechanism for a Valentine’s message. This could be a paper plane, paper spinner, zip line or any other creation that flies!
Write a Secret Message
Write a secret message with lemon or lime juice.
Lemon or lime juice makes a great DIY invisible ink for writing secret messages. Just pop the paper in the oven to reveal the message.
Blow up a Balloon Heart
This simple science activity uses an alka seltzer or baking soda and vinegar to blow up a balloon heart.
This Valentine’s Day scratch card coding activity from Code Wizards is great fun, too.
