In our science learning journey, we experimented with purple cabbage water as a pH indicator. We discovered that when various substances were added, the cabbage water changed color, revealing their acidic or basic properties. Acids, like apple juice and citric acid, turned the water red or pink, while bases, like baking soda, produced blue or green hues. Neutrals showed no color change, likely due to their high water content. Additionally, we constructed a pop gun using vinegar and baking soda, demonstrating a fun chemical reaction!

Cabbage Indicator • We used purple cabbage water. • The seniors added things and this happened –
Cabbage Water • 1. Went red or pink. These are acids- Apple juice, tartaric acid, citric acid. • Went blue, green or a different purple. These are bases (carbonates) – Washing soda, icing sugar, milk. • Some didn’t change. These are neutrals- cold tea, disinfectant. We think they didn’t change because they have a lot of water in them.
POP • Today we made a pop gun. • We used – • A bottle • A cork • Vinegar • Baking soda • We made a chemical reaction.
