The simplest science experiments are often the most fun, the ones you keep coming back to time after time. Especially if you have preschoolers looking for a messy busy activity. One of our most popular go-to activities is simply vinegar and baking soda..as a base. Even my 4th grader still enjoys these activities.
There are so many variations on what you can do with it, add a little food coloring, a few props and science items and you can create an experiment that lends itself well to any theme. Like this, Fizzy Heart Science Experiment- what a fun way to include a little Valentine’s fun in their day today.

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.
Place in the freezer for a couple hours.
Remove the hearts from the freezer
Provide your child with a bowl or cup of vinegar and droppers or syringes to use on their frozen baking soda heart.
The fun is in watching how the two react together to change texture and shape.
As they slowly add vinegar this experiment will last a little while but I promise you they will beg for more so I would have a couple hearts on hand!
