Three States of Matter: Orange Soda
Students learn about the three states of matter and how they might interact in one system using baking soda solid and orange juice liquid in a cup to produce "orange soda" gas.
A quick and easy way to demonstrate the three states of matter and how they might interact in one system. Combine baking soda solid and orange juice liquid in a cup to produce "orange soda" gas. Have students make predictions before the experiment and note observations during the reaction.
What You Need
Materials needed per student:
- 1 small cup for the orange juice
- 1 medium clear cup for the baking soda
- Orange juice
- Baking soda
What To Do
- Fill small cups with orange juice.
- Fill the medium cups with about a tablespoon of baking soda.
- Pour the orange juice in the baking soda.
- Watch what happens!
Discovery
The activity demonstrates how the three states of matter can interact together in a system. The orange juice is the liquid. When mixed with the baking soda, a solid, the acid in the orange juice reacts with the baking soda base to release carbon dioxide and water, which forms at the surface as bubbles and fizz, which is the gas.
