Dancing Compasses
Source Institutions
Learners use compasses to detect the magnetic field created by current moving through a wire. This is one of four activities learners can complete related to PhysicsQuest 2008.

Curious Contraptions
Source Institutions
In this engineering design activity, learners will design, test, and build a “haunting machine” to solve a Sherlockian mystery.

Watch It Fly
Source Institutions
Learners observe projectile motion by launching wooden balls off of a table top. They set up a rubber-band launcher so that each ball experiences a consistent amount of force.

Swinging Yo-Yo
Source Institutions
Learners build a pendulum from a yo-yo, and then design their own experiment to determine what affects the pendulum's period of swing.

Oh Buoy!
Source Institutions
Learners work in pairs to design, construct, and test a device that exhibits positive, neutral, and negative buoyancy. They test a number of different objects in water to see if they sink or float.

Designing a Wall
Source Institutions
In this engineering activity (page 5 of PDF), young learners investigate how materials and design contribute to the strength of a structure, particularly walls.
