Valentines Day science experiment for kids

Looking to do something different this year? Here’s a fun and easy Valentines Day science experiment for kids!

I love celebrating Valentine’s Day with the kids! It’s just fun to do things hearts and red and pink for a few weeks leading up to the big day.

One thing that is always a hit with my kids is baking soda + vinegar crafts. You know, your basic science fair volcano!

This is that – on a super small scale. It’s fun to make these baking soda hearts fizz!

This occupied my kids for about 15 minutes, which, considering they are 2 and 4, I will take!

More Valentine’s Day fun:

I did not have my kids wear goggles for this project, but best safety practices would be wearing eye protection!

Mix a few drops of red or pink food coloring into about 1/4 cup of water. Stir to combine.

Add 1/4 cup baking soda to a second bowl. Slowly add dyed water and stir with a spoon until you get a peanut butter consistency.

Spoon into heart molds.

Place the heart molds in the freezer overnight or until frozen solid.

Once frozen, you can pop out of the molds and into a plastic bag or container until you are ready to use them.

Give each kid a small bowl of white vinegar, a plate, and a dropper.

Let the kids dribble vinegar onto the hearts and watch them fizz!

Note that it helps to dump the plates off occasionally for a fresh, clean slate and the bubbliest effect.

You can also drop the hearts straight into a couple of inches of vinegar in a glass for another bubbly effect!

This was so much fun and a great way to talk about science leading up to Valentine’s Day!

Are you doing any fun science games for Valentines Day?!
