Practical Applications

Science in Your Kitchen

Experiments at Home

Your kitchen is a laboratory! Cooking and baking are all about chemical and physical changes.

What Happens When You Cook?

  • Chemical changes: Baking a cake causes ingredients to react and form something new.
  • Physical changes: Melting butter only changes its shape, not what it is.

Why It’s Useful

Knowing the science behind food helps you bake better cookies, avoid kitchen disasters, and understand nutrition.

Fun Activities

Try mixing vinegar and baking soda to see a fizzing reaction, or watch yeast make bread rise.

Examples

  • Baking bread and watching the dough rise due to yeast fermentation.

  • Melting chocolate for dipping fruit.
