Acids and Bases

This week 4th class were busy working with acids and bases. Using the volcanoes we made during art, we investigated what happens when an acid and a base are mixed together.

Our base was bread soda and we changed the acids for each experiment: White vinegar, tomato sauce and lemon juice. We learned about the pH scale.

The mixture of bread soda and lemon juice had the best result because lemon juice is such a strong acid - pH 2.
