Introduce your class to magnetic fields with an activity that demonstrates that a compass is affected by the magnetic field of the earth, unless a closer, stronger magnetic field is present. Pupils can use this fact in the...

The surface of the moon has an amazing tale to tell. Learn about the moon's story with a PowerPoint presentation that describes the unique features of the moon's surface as well as explains its movement in relation to Earth.

Six simple images pull your class into magnets. Most of the pictures show magnetic fields as revealed by iron filings. Concepts are explained in print along the bottom of each slide and include magnetic force, force fields, poles,...

The compass was first used in 206 B.C., but we didn't discover magnetic poles until 1263 A.D. Presentation begins with the history of magnetism before continuing on to magnetic fields, magnetic forces, electromagnets, currents,...

Every knows that opposites attract! Here's a presentation that uses this background knowledge to explain magnetic fields and forces. The resource also explains the shape of magnetic fields and how to determine the direction of forces.

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...

The biggest magnet in the world is at the Los Alamos National Laboratory in New Mexico and can reach 100 tesla. By comparison, magnets that lift cars are about two tesla. The 11th presentation in this series covers magnetism,...

A radio receives radio signals, converts them to an electrical signal, then converts this signal to a sound signal, and amplifies the sound so people can hear it. Class members use this information to create a short-wave radio antenna...

How do Earth's changes affect humans? Pupils learn about physical and chemical changes on Earth and how they lead to erosion, earthquakes, and volcanoes. Using the text, they also explore the concepts of electricity and magnetism by...

Is this the end of the world as we know it? Pupils prepare for a coronal mass ejection during a lesson from the K20 Center. The activity combines video and Internet research in a collaborative assignment that focuses on public safety...

You matter, unless you multiply yourself by the speed of light ... then you energy. Presentation covers the behavior of light as both a wave and a particle, light versus sound, space travel, why objects have colors, depth perception,...

What is a physicist's favorite part of sports? Doing the wave. The presentation covers longitudinal, transverse, surface, and standing waves. It includes in-depth information on frequency, wavelength, period, amplitude, reflection,...

The propellant needed for space explorations runs in the thousands, while paying to get the craft into orbit costs millions! In the second installment of three, two activities explore laws of conservation of energy and momentum. Using...

The phonemic awareness activities in this packet are designed to help kids develop skills in rhyming, syllabication, blending onsets and rimes, and beginning and ending sounds. Well worth a place in your curriculum library.
