Anytime I tell the kids that they get to have their hands get a tad bit messy, they’re on board 100% for any type of learning activity fun. And while this fizzy STEM activity is fun, they love that it’s a Valentine’s Day themed activity as well.

I’ve found that over the course of my teaching the kids at home, they really respond well to themed activities and themed learning packets. It just helps them find a tad bit more excitement in gearing up for learning for the day.

Using this science activity is such great motivation!

Fizzy Hearts Instructions

Determine how many hearts you want to make, this experiment is pretty fun and the kids will beg for more so mix up a good-sized batch!

In a large bowl place your baking soda and slowly add water, mixing with a spoon first and then your hands to get it well mixed. You want it just a bit wet but still firm, like a gritty toothpaste.

To make it themed for Valentine’s day add some red food coloring and glitter for good measure.

If you are using cookie cutters place them on a baking sheet or another pan.

Press your mixture firmly into each cookie cutter to fill.
