In this activity, learners identify different classes of matter based on physical properties.

In this activity (pages 42-49), learners discover the methods and challenges of building nanoscale structures with macroscale equipment.

In this activity, learners will listen to as many radio stations as possible to discover that AM radio signals can travel many hundreds of miles at night.

Learners drop a magnet through a coil of wire to create electric current in a circuit. LEDs in the circuit allow learners to detect the direction of current flow.

Learners observe a simple balloon model of an electrostatic precipitator. These devices are used for pollutant recovery in cleaning industrial air pollution.

Learners use the current flowing in a wire to create a magnetic field that turns a magnet. Learners can use this property of electromagnetism to build a magnet-powered pinwheel.

In this activity, learners investigate static electricity using everyday objects at four different stations.

In this activity (pages 32-41), learners learn how the atomic and molecular arrangement of matter are related to physical properties.

Do grapes, yes the grapes from the grocery store, move in the presence of a very strong magnet?

In this activity, learners light an LED with five cents. Learners use two different metals and some sour, salty water to create a cheap battery.

Learners are challenged to create solutions that conduct electricity and make a buzzer buzz (or an LED light up).
