This activity promotes student understanding of some of the movements that take place when warmer water and cooler water interface, and how differences in densities, resulting from variations in temperature, set molecules of liquids and gases in... (View More)

This experimental activity is designed to develop basic understanding of the relationship between the angle of light rays and the area over which the light rays are distributed, and the potential to affect changes in the temperature of materials.... (View More)

This exploration engages students in an investigation that leads them to the conclusion that regions of the electromagnetic spectrum vary according to energy per photon, and connects with the video where Dr. Ilana Harrus explains observing a... (View More)

Audience: High school

This is a lesson about the magnetic field of a bar magnet. The lesson begins with an introductory discussion with learners about magnetism to draw out any misconceptions that may be in their minds. Then, learners freely experiment with bar magnets... (View More)

Audience: Middle school

This activity demonstrates Lenz's Law, which states that an induced electromotive force generates a current that induces a counter magnetic field that opposes the magnetic field generating the current. In the demonstration, an empty aluminum can... (View More)

This is an activity about magnetic induction. Learners will induce a flow of electricity in a wire using a moving bar magnet and measure this flow using a galvanometer, or Am meter. Through discussion, this activity can then be related to magnetic... (View More)

In this activity, students work in groups to create a presentation that illustrates the meaning of the statement "To make an apple pie from scratch you must first invent the universe." Students pick an element that can be found in apple pie and... (View More)

This is an activity about electromagnetism. Learners will set up a simple circuit using a battery, wire, and knife switch, and then use a compass to map the magnetic field lines surrounding the wire. Next, they will add a coil of wire to the simple... (View More)

In this activity, students will model the time after the Big Bang when the first nuclei of hydrogen and helium were created. The students will move and display cards that show the elements that are formed. This activity requires a large area - e.g.,... (View More)

In this activity, students experience a demonstration of light scattering that explains the blue colors in the Intersetllar Medium (ISM) nebulae, and the reddening of stars viewed through the ISM. It also explains the blue appearance of the sky on... (View More)
