Super-Fun Valentine’s Day Science Activities

The weeks leading up to Valentine’s Day is the perfect time to show love and kindness to others, tell someone you care, and… get messy and explore science concepts?


10 Super Fun Valentines Day Science Activities



It’s the perfect time to have a little Valentine’s Day science fun with your kids. Grab some simple supplies and you’ll have the makings for all of these great ideas and more.


Colorful Candy Conversation Hearts

Conversation Heart Science

Conversation hearts are inexpensive. You can grab them in just about every store this time of the year. And you can do so much with them.

You can try this fun experiment from Fun-a-Day and have your kids work through the scientific method themselves.

I love number two in this post that shares five different activities you can do with candy hearts. We’ve tried it with raisins before, but never Valentine’s Day candy.

Dissolving conversation hearts is always fun, and this experiment looks great.

Did you know that conversation hearts react with baking soda? I didn’t until I ran across this post from Imagination Laboratories. We’ll be trying this soon.


Valentines Day Sensory Science

Sensory Valentine’s Day Science Play

Sensory activities are science when you turn them over to the kids, and let them experiment and give them free reign to add different materials. We’ve tried a few of the following ideas, though our results aren’t always as picture-perfect, but the little scientists that live here are enjoying their discoveries and can now make perfect slime.

Though this conversation heart goop wasn’t exactly perfect, it was really fun. Slime was the original expectation, but since the candy dissolved in the slime, and made it runny, the kids declared it goop and played for hours.

The slime from Little Bins for Little Hands turned out much better than ours, so if you’re looking for a little bit of polymer science to celebrate, try this out.

I adore this foaming heart science activity from Two-da-Loo. Baking soda and vinegar science often turns into sensory play for my little scientists because they can’t resist getting their hands into the mix.

Need something to help ward off cabin fever? Try this amazing Love Potion Lab that the folks at Bath Activities for Kids set up. I think I’ll be using this one soon.

Since love is in the air, here are some more love potion activities for you to try with your kids – I love the fun shaped containers.
