Valentine’s Day is a great time for STEM activities! From fizzing hearts and surprise messages to heart logic puzzles and building challenges, there are lots of Valentines Day STEM activities and experiments to make the day special.
Below is a collection of various science, technology, engineering, art and math activities with a Valentine theme. If you have been following me for awhile, you know that I love a great STEM challenge for kids.
STEM challenges and activities include at least one science, technology, engineering or math skill. The more of these subject areas that are touched on in a activity the better. Recently an art component has been added to these special activities, sometimes now known as STEAM activities.
When I taught kindergarten, STEAM activities and science experiments were always my go-to activities because the kids always loved them! Whether you are looking for activities to try at home or in the classroom, there are lots of simple STEAM activities to try out!
