Opposites Attract

Students explore the concept of magnetic attraction. For this magnet lesson, students carry out the steps of the scientific method as they develop and test a hypothesis regarding magnetism.

Atomic bombs harness the power in the nucleus of an atom, creating devastating power and damage. Classes review parts of an atom by charging a piece of plastic and holding it near their fingers, discussing what is happening and why....

Attracted class members to an activity-packed journey through the science behind the invisible forces at work all around us. From jump rope generators to junkyard wars, there's never a dull moment when eighth grade physics scholars...

A water strider is a bug that taps into the attraction between the positive and negative ends of water, allowing the bug to walk on water. Learners view short videos showing polar characteristics of water. Pairs then discuss what polar...

Young electrical engineers use balloons, cereal, and PVC pipe to test how positive or negative charged particles can attract or repel each other. First they attract Rice Krispies with a static-charged balloon, and then they use two...

Conduct four electrifying electricity experiments that challenge young scientists to explore positive and negative charges and magnetic fields without the shock.

The different types of molecular interactions, and the impact they have on boiling, melting, and freezing points of different substances, is the focus of this chemistry video. Sal goes over Van Der Waal Forces, London Dispersion Forces,...

Like all electricity, static electricity flows at the speed of light, or 186,282 miles/second. The interactive simulation shows how like charges repel like charges and opposites attract. The user can choose either one or two balloons, a...

Have your young scientists create electroscopes and conduct an experiment using various types of materials (some conductors, some insulators). What happens to the electroscope when each object is passed through its plastic pieces?

Students classify objects that magnets are attracted to and aren't attracted to. They also magnetize metal. They construct and use a compass. They develop a product which show they explain the properties of magnetism.
