Loony Balloons
Source Institutions
In this activity, learners investigate how changing the center of gravity of a balloon affects how it travels. Learners fill a balloon with a little bit of water and insert into an empty balloon.

Cylindrical Wing
Source Institutions
In this design and physics challenge, learners construct a cylindrical wing, fly it, make modifications, and determine how the changes affect flight patterns.

Building a 3-D Space Maze: Escher Staircase
Source Institutions
In this activity (page 95 of the PDF), learners create Escher Staircase models similar to those that were used by Neurolab's Spatial Orientation Team to investigate the processing of information about

Bernoulli Brain Teasers
Source Institutions
In this activity related to flight, learners conduct two simple tests to explore how lift works.

Squeeze the Stream
Source Institutions
In this activity related to flight, learners build a tiny stream channel to investigate how fluids (air and water) change speed as they flow between and around objects.

Newton's in the Driver's Seat
Source Institutions
In this playful physics activity (page eight of the pdf), learners use toy cars to explore how speed and weight affect the results of collision.

Bouncing Balls
Source Institutions
When baseball was in its infancy, the ball had plenty of bounce. Today's baseball may not seem to have bounce to it at all; if you drop a ball on the field it won't bounce back.
