An illuminating activity demonstrates how interference of light waves creates a pattern. Using Plexiglas™ and construction paper, participants see rainbows appear as they twist or press against the plastic plates. After the activity, you...

Wave goodbye to the same old demonstrations for alternative energy sources, and wave hello to this one investigating ocean waves! Using a water bottle to create an oscillating water column, learners see and possibly hear how the...

How did scientists discover what lies beneath the earth's surface? Dig a hole? X-ray vision? Guide your class through the types of seismic waves and how these waves helped shed light on Earth's many layers. The included resources provide...

Kindle knowledge of how light travels by using this activity in your physical science curriculum. By setting up a candle flame or flashlight bulb and viewing it through a slit, observers of light see evidence of its wave characteristic....

Learning about waves can have its ups and downs, but a demo-packed tool kit has the class "standing" for more! Learners gain experience with several different wave types, organizing observations and data, and wave...

Finally, an electromagnetic spectrum lab that will get glowing reviews from your class! Explore the nature of light using red and blue LED sources and fantastic phosphorescent paper. Young scientists compare the effects of blue light...

If you set up a triad of mirrors into a corner figuration, they act as a kaleidoscope, bouncing light waves back and forth indefinitely, changing the light that your eyes perceive. Although the materials required are very specific and...

If you are up for constructing a wooden frame, you can do this demonstration of the interference patterns when light reflects off of layers of soapy film. Both constructive and destructive interference can be seen as evidenced by the...

Use a container full of water as a prism and show that as light is bent, the individual colors from different wavelengths become visible. This explains why the sky appears to be blue midday, and why as the sun nears the horizon, it looks...

Uncover the science behind the beautiful phenomena of rainbows with a simple demonstration. Shine light through different-sized containers of water as young scientists learn that rainbows occur when visible light is split up into its...

Using flexible mirror-like paper, physical scientists experiment with images produced by curving it and looking into its reflective surface. They find that concave mirrors cause reflected light waves to cross and actually flip the image...

Lighten up a bit with this activity! Use an old-fashioned overhead projector to shine light through a pair of polarizing filters. Place a stressed plastic object in between and display the colors of light waves revealed! Rotate the...

Is it possible to change the color of clouds? A three-part activity explores the scattering of light by the water droplets that make up clouds. After observing a demonstration, curious scholars conduct their own investigations of the...

Make sound visible with an activity that provides directions for how to build a vocal visualizer meant to create light patterns. Making noise into the visualizer causes a mirror to vibrate, reflecting a laser beam, and creating...

Reflected waves of light move within a plane, and because of this, polarizing materials can reduce the glare our eyes see. This resource explains how to set up a demonstration of this effect. Consider it for use in your physical science...

Not only does a concave mirror focus light waves, it can also concentrate infrared radiation into a hot spot. If you have a small electric heater and such a mirror, demonstrate this for your physical science class.

A two-part lesson asks young scientists to research the contributions of African American scientists at Bell Laboratories. After presenting their findings, class members watch two demonstrations that introduce them to total internal...

Create jumbo bubbles and use them to teach about surface tension or interference, perfect for a physical science lesson on light or molecular attraction.

Scientists used flame tests to identify elements long before the invention of emission spectroscopy. Young chemists observe a flame test of five metal cations in the fourth instructional activity of an 11-part series. Individuals then...

What is the difference between a comet and a meteoroid? An educational lesson includes five demonstrations of how the atmosphere can inhibit our ability to measure many things in the galaxy. 

An informative physics lesson includes two teacher demonstrations, one on AC currents and the other on DC currents, allowing pupils to take notes while watching. The resource includes questions to assign as homework or...

Whether you want to heat things up in science class or cool things down a bit, an intriguing lab's got you covered! Science scholars explore the principles of thermodynamics using a solar oven, then change the conditions to turn their...
