Valentines Day Science & STEM Projects

Valentines Day Science Activities for Kids

It’s true. I heart Valentine’s Day! I mean, love is just such an awesome concept, why not celebrate it?

And of course, my favourite way to celebrate is with science! Here are some of the Valentines or heart themed science activities we’ve done so far – and more coming soon!

Fun Valentines Day Science and STEM Ideas from Go Science Kids

Check out these awesome Valentines STEM ideas from around the web. Love these!

  • February is all about hearts, why not try making a working heart model, that really pumps! This one from Team Cartwright uses cups and a balloon, whereas this one from STEAM Powered Family uses plastic water bottles. Try making both and see which one works best!
  • You could also try making a realistic 3D heart model with playdough, from STEAMsational.
  • This is cool. Did you know you can draw hearts and then make them float? You can even chase them around with a paper straw! From STEAM Powered Family.
  • Raising Dragons has another floating hearts challenge, using magnets!
  • Can you balance a heart? ‘Love’ this centre of gravity idea that Babble Dabble Do shared at Red Ted Art.
  • If you prefer tasty STEM activities, try making heart candy structures! From Little Bins for Little Hands.
  • And of course, if all else fails, you could always make slime! (Making your own slime totally counts as a chemistry lesson, right?) This one is pretty from Artsy Fartsy Mama, or this one uses liquid starch, from STEAMsational, and this one from Little Bins for Little Hands includes tiny heart glitter pieces.

Do you know any fun heart or Valentines Day science projects we should try next?
