In this oceanography and data collection activity, learners cast real time sea state conditions using buoys from NOAA's National Data Buoy Center.

Learners build a simple hovercraft using air from a balloon to levitate a craft made from a compact disc (CD).

Learners construct a rocket from a balloon propelled along a guide string.

Learners make a skydiver and parachute contraption and launch it. They see that the drag created by air resistance slows the descent of skydivers as they travel back to Earth.

Demonstrate the Bernoulli Principle using simple materials on a small or large scale.

Learners build at least two different spinners (tops) to investigate how mass distribution, size, and shape affect the length of time the spinner spins.

Learners explore the concepts of equilibrium and center of mass by seeing how non-symmetrical objects balance.

Learners build a model of a pollution control device--a cyclone. A cyclone works by whirling the polluted air in a circle and accumulating particles on the edges of the container.

Learners construct and launch paper helicopters.

To learn how friction affects motion, learners build a measurement tool from a rubber band and other simple materials.

This is a quick activity (on page 2 of the PDF under Gecko Feet Activity) about the forces of gravity and surface tension and how their behavior is influenced by size.
