Baking soda and vinegar experiments are a quick and easy way to teach preschoolers about acids and bases as well as what happens when they combine. Plus, they’re a fun way to add even more STEAM learning to your next ocean preschool theme.

For today’s experiment, we made lots of adorable ocean animals using baking soda, water, and food coloring. We found an ocean-themed silicone mold that included a seahorse, dolphin, starfish, and more. These sea creatures are super easy to make and lots of fun.

  • Mix together baking soda and water to make a paste. We also added a few drops of food coloring to give our sea creatures a little bit of color. If you’d like to make your ocean animals lots of different colors, just split up the baking soda and water paste into a few different cups before adding the food coloring.
  • Place the silicone mold on a tray. Then, use a spoon to scoop the baking soda and water paste into each section of the mold. Put the tray into the freezer for several hours. I usually prepare activities like this one the night before so that everything’s ready to go in the morning.
  • Remove the sea creatures from the silicone mold and place them directly on the tray. Fill a squeeze bottle with vinegar or set out small cups of vinegar and eyedroppers. Encourage children to explore what happens when baking soda and vinegar mix together to create a really fun chemical reaction.

Experiments like this one create an acid-base reaction. Vinegar is an acid and baking soda is a base. When they combine, they create a fizzing and bubbling chemical reaction that’s sure to delight your little learners.

Classic science experiments are perfect for little learners. Not only will your preschoolers and kindergartners want to do this fun STEAM activity over and over again, but they’ll also be exploring important science concepts in the process.

We love STEAM activities because they’re so incredibly versatile. For preschoolers, just the simple fact that we’re mixing together an acid and a base and making a chemical reaction is perfect. For older kids, we can have more in-depth discussions about acids and bases, chemical reactions, and so much more.
