In this activity learners will investigate magnetic and non-magnetic items in a sensory bottle.

In this activity, learners sort different natural phenomena into categories (they occur on Earth, on the Moon, or on both), and then model how energy moves during a quake using spring toys.

In this activity, learners explore trebuchet design. Teams of learners construct trebuchets from everyday materials.

In this activity, learners explore moving air and the physics of lift and drag by constructing homemade wind tunnels.

In this physics activity, learners assemble and/or investigate a pendulum "snake." Several large steel hex-nuts are suspended on strings of successively increasing length to form a series of pendulums

In this design challenge activity, learners invent a pinball-like game where a kick stick hits a ping pong ball into a target that buzzes.

In this activity, learners build mini-basketball courts and explore the laws of physics. Learners discover that everything you throw or shoot on earth travels in a parabola.

Learners observe working lava lamps to understand how they work (included in PDF link).

In this invention challenge activity, learners create an indoor game for one or two people that gets you moving.

In this activity, learners are challenged to design and construct a jointed figure that moves in a motion (something like jumping jacks) when a string is pulled.

Build your own version of the classic physics toy using simple materials.

In this activity, learners explore the history, design and motion of spinning tops. Learners work in teams of "engineers" to design and build their own tops out of everyday items.
