K–5th Grade

Reaction Action

Students compare physical changes and safe chemical reactions using color, gas formation and measurable evidence.

Science focus

Changes in matter and scientific evidence

Best for: Elementary classrooms, camps and groups that want visible chemistry.

What children take from it

  • Distinguish a prediction from an observation
  • Compare physical changes and chemical reactions
  • Use visible evidence to explain a result

How the session is structured

  1. NoticeA visible question or phenomenon gets the group thinking.
  2. InvestigateChildren test, compare and contribute instead of simply watching.
  3. Build or applyAn age-matched challenge turns the idea into action.
  4. ExplainThe group connects what happened to the science concept.

Room requirement

Tables and chairs · nearby sink access. Final layout and activity boundaries are confirmed with the host before booking.
