What Does It Mean? 🤔
Let's learn together
🌋
Carbon dioxide is an invisible gas all around us. People and animals breathe it out, plants use it to grow, and it is also what makes a lot of fun fizzing happen in science experiments!
When Freddy mixed baking soda and vinegar, bubbles of carbon dioxide gas formed so fast that they pushed everything up and out in a foamy eruption — just like a tiny volcano!
Carbon dioxide is also what makes soda fizzy. The bubbles you see and the tickle you feel when you drink it are tiny pockets of carbon dioxide gas escaping out of the liquid.

👨👩👧 Teaching Tips
Connect carbon dioxide to breathing and plants in addition to fizzy reactions, so kids understand it is a real everyday gas and not just something from experiments.
🏫 Classroom Ideas
Run the baking soda and vinegar volcano as a class demonstration, then ask students to name other places they have seen bubbles or fizzing that might involve carbon dioxide.
