What’s the difference between a demonstration (demo) and an activity?

  • Demo

    • Shorter (10-15 minute) demonstration of scientific principles.

    • Tailored to the age and scientific background of the audience.

  • Activity

    • In-depth, interactive, and hands-on experience (20-30 minutes).

    • Individual participation experiments create and builds with the guidance of trained staff or volunteers.

    • Tailored to the age and scientific background of the audience. Ask us about how we can tailor our activities to fit your educational needs, including educational goals for classrooms that meet Indiana state science standards and merit awards for scouting organizations.
