It doesn’t really matter what day of the year it is, chemistry experiments for kids are always a blast! They certainly create quite a reaction around here. All puns intended. We won’t be getting into the chemistry of love, but we can get into some fun Valentine’s Day chemistry experiments and science activities with a heart theme. Read on to find out how to create your own chemistry Valentine.

Valentines Day Chemistry Experiments for Kids Valentines SciencePin

Chemistry Valentines

What exactly is chemistry? Simplified, it’s how things interact, combine, and change. Now, this can be talked about with people’s personalities and substances. Sometimes chemistry and physics overlap, but we will call this list chemistry.

Read more about Chemistry here.

Here, we will show you some great Valentine’s Day science activities with crystals, baking soda and vinegar, PVA glue, chocolate, and more! You will mix love potions, grow crystal hearts, make cool Valentine slime, and more as you prepare for Valentine’s Day!

Chemistry explores the tiniest building blocks of matter called atoms. These atoms join together to create molecules like the building blocks of everything you see and touch. Chemistry helps us understand how these molecules behave and react with each other.

Learn more about atoms and make atom models!

Think of it as mixing paint colors to create new shades or combining ingredients in a recipe to make your favorite cookies. Chemistry is like that mix-and-match game but on a super tiny scale!

Don’t forget our free printable science valentines to pass out!

Chemists also study reactions, like when you mix baking soda and vinegar, and it fizzes up. That’s a chemical reaction! Chemistry helps us understand why these reactions happen and how to use them to make new things.

So, chemistry is all about exploring and understanding the incredible world of tiny particles and how they come together to create the fantastic stuff that makes up our world!
