Put Valentine's Day-themed candies to use in science class with one of these fun hands-on STEM activities.

Three STEM projects for Valentine's Day, including candy hearts that dance in carbonated water, a robot decorated with craft materials to deliver candy, and colorful candy diffusion chemistry in a bowl.

Conversation hearts, candies, and a robot that delivers!

It is easy to give a Valentine's Day spin to hands-on science and engineering activities with students. Candies in Valentine's Day colors work well for a range of science projects, and many engineering projects can be recast for Valentine's Day by making colored papers, tape, and craft materials available. For liquid-based projects, add a few drops of red or pink food coloring to add Valentine's spirit.
