🤔 Making Predictions and Hypotheses

9. Before we started, what did you think would happen?

My prediction for the vinegar and baking soda: ________________________

My prediction for the elephant toothpaste: ____________________________

10. Why do you think these reactions happened? (Circle your best guess)

The materials mixed together and changed into something new

The materials just got stirred up

Magic happened

I'm not sure

11. What do you think the bubbles and foam are made of?

🔬 Reflection and Learning

12. Complete these sentences about chemical reactions:

When materials react together, they can make _________________ things.

I know a chemical reaction is happening when I see _________________ or _________________.

Chemical reactions can make gases like _________________ that create bubbles.

13. What was the most exciting part of today's experiments?

14. Can you think of chemical reactions that happen at home? Write or draw one example:
