Halloween is perfect for a few crazy, and a bit scary, science activities! So this week, we are sharing a crazy color-change activity, plus a few other Halloween science activity round-ups to give you a few ideas.
Part color-change, part stink-up-the-kitchen – this Halloween science activity requires a bit of preparation, but it is totally worth it. Plus in the process, you can teach your kids about acids and bases.
Let's dig in...
Red cabbage juice acts as an indicator of pH, which is a fancy way of saying that it changes color – in the presence of an acid.
The juice can turn pink and in the presence of a base, it can turn bright green. Ammonia is a base, vinegar is an acid.
