Every year our preschool class learns about ocean life. Sometimes I teach the topic using the letter “O is for Ocean.” Other years, I build the day around the letter U and teach it as “U is for Under The Sea.” Either way, it is so much fun – especially with this under the sea fizzing sensory activity!

This preschool lesson includes an Ocean Paper Plate Craft that little children just love to make, teamed up with this ocean fizzing activity. As we are winding down at the end of school, I read them the adorable story “The Pout Pout Fish [A Pout Pout Fish Adventure]” It makes for a perfect day.
You know how children love surprises? Well, there definitely are surprises built into this sensory experience. The children will each discover a hidden treasure inside their own baking soda ball [how-to make them below] that you have placed in the sensory bin. Just give each student a squirt bottle filled with white vinegar, tinted blue with food coloring. Have them squirt their baking soda ball until it dissolves, revealing a little plastic undersea animal toy, which they can keep.
Think about it. This under the sea fizzing experience introduces them to basic chemistry – vinegar, when it meets baking soda, FIZZES! Of course, before you are finished, add water to the bin to let them play. Kids LOVE to play with the toys in the bin.
