Integrated Sciences (Biology, Chemistry, Physics)
Your child can identify signs of a chemical reaction (temperature change, gas production, color shifts) and read pH levels using indicators.

Your child makes red-cabbage indicator in the guesthouse kitchen and tests everything in reach. Lime juice turns it pink (acid), baking soda turns it blue-green (base), and the fizz when they meet is a real chemical reaction.
