Science in the class

We have been doing some science about substances in the kitchen.
We mixed acids and carbonates together to see what reaction we would get. When we mixed baking soda and vinegar it fizzed releasing carbon dioxide.
The next day we made sherbet. The next day we blew up balloons with salt and soda water, as well as baking soda and vinegar. Then we made the baking
to see how heat helps release carbon dioxide.
