Science + Literacy

Incorporating science into literacy is easier than you might think. Acid base experiments like those using baking soda and vinegar, lend itself to literacy incorporation just by adding plastic letters to the activity. Depending on the age of the child, the letters can then be used for letter recognition, sound recognition, or even making words. Plus kids love guessing what surprise letter will appear when the reaction takes place.

Plastic Letters


Did you get Chocolate for Christmas? Don’t trash those plastic inserts just yet! Add a plastic letter to each spot then cover with baking soda. Use vinegar to reveal the hidden letter.

Preschool Prompts

What do you think will happen when you add vinegar (an acid) to the baking soda (a base)? Describe what you see, hear, smell, and feel when before and after the reaction. What letter did you find? What sound does that letter make? What words begin with that letter? Can you make a word using some of the letters you found?
