What is electricity? How is it created, and what makes it useful? Physics - Electricity And Circuits - Learning Points. Electricity is a flow of charge. The flow of moving electrons is known as the electric current. Voltage is the amount...

We use two magnets and a set of scales to examine magnetic field and strength. One magnet is attached to the scales and a second is lowered towards it. When opposite poles are facing each other, the weight on the scales decreases as the...

We use a Van de Graaff generator to investigate static electricity. The generator is turned on and we see a spark move between the two domes. We then place a wig on the main dome and see the hair rise as the charge builds and the hairs...

We use a disposable nappy to examine the superabsorbent properties of hydrogels. We add water to grains of hydrogel and watch them swell before adding salt to see the water escape. Chemistry - Chemical Industries - Learning Points....

Dr. Forrester discusses the properties and uses of magnets by classifying objects as magnetic or nonmagnetic.

Dr. Forrester defines static electricity by conducting a simple experiment using a balloon. She also identifies the two types of electricity by describing static electricity and current electricity.

Dr. Forrester teaches that magnetism is a force that pushes and pulls on other objects. She defines: gravity, attract, and repels. She teaches about forces that attract or repel other objects and lists principles of magnetic behavior.

“Effects of Magnetic Fields” reviews the concept of a magnetic field and demonstrates how a magnetic field can be shown using simple iron filings and bar magnets.

Magnetic Forces explains the properties of magnets by describing characteristics and defining magnetic forces.

The video “The Essential Electric Motor” explores the components of electric motors and gives examples of how these motors are used in everyday life.
