Jumping Corn - Baking Soda and Vinegar Preschool STEM
- Pose “what,” “why” and “how” questions about their surroundings
- Make predictions, perform experiments, and discuss results
- Use 5-senses to make observations
- Fill a clear jar or glass about halfway with water.
- Add popcorn kernels to the jar.
- We used 1/4 of a cup, but you can certainly get away with less.
- Pour some vinegar in the jar.
- We didn’t measure, which was very unscientific of us, but I would say about 1/4 of a cup.
- Before adding the baking soda ask your preschooler, “What do you think will happen when we add the baking soda?”
- Add a teaspoon of baking soda and get ready for a reaction.
- Talk with your preschooler about what they see, ask them to describe what’s happening.
- This will be deepen their comprehension of the experiment they just engaged in and it is an opportunity for them to engage in the scientific process in an oral format.
Having a jar with a lid came in handy because we quickly put the lid on the jar. This prevented any spilling and it forced the gas created from the reaction to stay inside the jar which led to more movement of the kernels.
To make life a little easier on you I have put all of this in a printable PDF lesson plan.
