In this activity, learners use a straight line to learn about circles. Learners measure and record the diameter and circumference of different sized cylindrical objects on a chart.

In this activity, learners make a black box device that serves as an excellent analogy to Rutherford's famous experiment in which he deduced the existence of the atomic nucleus.

In this demonstration, cook a cake using the heat produced when the cake batter conducts an electric current.

In this activity, learners use a compact disc to make a spectrometer, an instrument used to measure properties of light.

In this activity, learners make cool boxes out of old (or new) greeting cards or postcards.

In this activity, learners make a simple spring-like scale using a rubber band instead of a spring, and calibrate the scale in newtons (N).

In this group activity, learners make multi-sided polygons with string.
