Lesson plan

Chemical reactions

Do two activities from the selection, to show chemical reactions. Choose food-related ones for a Chemistry of Cooking / Foods workshop.
Science content
Chemistry: Atoms, Molecules (3-7)
Chemistry: Chemical Changes (2, 7)

Pair two activities for a lesson.
Include molecule models for older primaries and up.

A chemical reaction happens when we see a new product: a new state of matter (e.g. gas bubbles or a solid precipitating), or a new colour or smell.
