Ducky demo 2

Now we’ll leave the predictable path and see what our minds can come up with as ways to change the speed at which the ducky moves.

Materials: dunking duckies, energy absorbing/releasing things like ice, lamps, etc..

Forces Drop Test demo

  1. Get two pieces of foil weighing 3 grams each.
  2. Ball one up, and leave the other a sheet.
  3. Drop both from the same height at the same time.
  4. Marvel at how 2 pieces of foil, identical in mass, fall at different rates!

Materials: 2 pieces of foil, each 3 grams (or whatever mass you decide them both to be)

Gravity demo

An unforgettable way to demonstrate many common forces at work all throughout our universe- like gravity and centripetal. Takes time to prepare, but once done you’re set to use on a moment’s notice.

Materials: small cup with water, ‘flippy board’ (instructions to build are on this video) made from masonite (also called hardboard) and string

Water Cycle demo

A clear way of seeing the water cycle go both ways- energy in and energy out.

Materials: 2 beakers/glasses, plastic wrap, rubber band, ice, lamp, water

Stellarium

Did you see the Geminids meteor shower?  It was incredible!

Whether you did or didn’t, with Stellarium you can still simulate it on a computer for your students.  That and about 100 other things can be shown.

Celestia is another free planetarium, but not nearly as user-friendly.
