Montessori Monday–Using Eye Droppers to Study Acids and Bases

Vinegar and Baking Soda with Eyedropper

Last week, I encouraged Dora to practice using eye droppers by filling bottles with colored vinegar and giving her a pan of baking soda. She enjoyed the explosive reaction, though she struggled some with using the eye droppers. Eventually, I let her her pour directly from the bottles, so she could get a super impressive reaction.

The next day, she asked to juice some oranges, but didn’t like the taste of the orange juice. So I thought we could use the orange juice to delve deeper into the study of acids and bases. We tried pouring the orange juice into a pan of baking soda. Then we tried lemon juice. I wanted to make sure that she understood that not all liquids would bubble when they interacted with baking soda, so we also tried some other liquids, such as milk and water.
