Corner Reflector
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...

Hot Spot
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.

Magnetism
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,...

The Absorption of Solar Energy
Two sequential parts to this lesson introduce your class to the electromagnetic spectrum, the ability to absorb radiant energy, and the pigments in leaves that are responsible for collecting sunlight to be used in the photosynthetic...
Oceanic Research Group
Heat Transfer and Cooling
Astronauts train underwater to simulate the change in gravity. An out-of-this-world unit includes three hands-on activities, one teacher demonstration, and a discussion related to some of the challenges astronauts face. Scholars apply...

Sound
Since light travels faster than sound, some people may appear bright until you hear them speak. The presentation covers what sound is, how fast it travels in various mediums, properties of sound, hearing, and the parts of the human ear.

The Science of Tsunamis: Seeking Understanding in the Wake of Tragedy
Learners use Internet research, articles, discussion and models to explore the dynamics of a tsunami. They focus on the 2004 Asian Tsunami and create posters illustrating their understanding of this phenomenon.
Curated OER
How the Ear Receives Sound
In this biology activity, learners identify how the ear receives sound by using the information given to cut and paste each section to complete a flow chart that illustrates this. They lightly color each section of the flow chart to...
Curated OER
Ocean Power
Students explore the energy resources of the ocean. For this energy lesson, students participate in 4 activities focused on energy resources from the ocean.
Curated OER
Coral Bleaching
Students examine the relationship between corals and zooxanthellae, identify stresses to corals, and explain coral bleaching. In this sea life lesson plan students predict the effects of increased temperatures on coral reefs.
Curated OER
Pitch
Students experience sounds with different pitches. In this pitch activity, students use open pipes as they are introduced to pitch, then make Straw Pan Pipes.
Curated OER
Using the Spectrometer
In this physics learning exercise, students observe white light through a spectroscope and describe what they see. Then they observe fluorescent light with the spectroscope and describe what they see. Students also describe why it is...
Curated OER
Sound Observations
Young scholars explore sound waves by conducting an experiment in class. In this sound frequency lesson plan, students utilize a tuning fork in class and identify which objects in class create different sound pitches on the fork. Young...

How Does Sound Travel As Waves?
Seventh graders participate in a number of activities designed to increase their understanding of how sound is generated and how it travels.
Curated OER
Waves Lesson Plan
Students demonstrate an understanding of tsunamis and possible causes. In this investigative lesson students view a video and explore earthquakes and movement of tectonic plates.
Curated OER
The Physical Environment
Fourth graders use damp sand, a baking pan, and water to simulate erosion. In this erosion lesson plan, 4th graders participate in a simulation to show what moving water does to land.
Curated OER
Riding the Gravity Wave
Students write a sketch of an artist or athlete that has pushed the limits on gravity. They explore concepts of rhythm, balance and friction. They examine how engineers design sports equipment.
Curated OER
Electric Circuits
Students model the flow of electrons in a circuit, draw diagrams of an electric circuit and build an electric circuit. Students explain how to tell when the path of an electric circuit is complete, and test the conductivity of a variety...
National Nanotechnology Infrastructure Network
Jell-O® Waveguide and Power Loss
Jell-O® can help model the transmission of light through fiber optic cables. Young scientists use the jiggly dessert to make a waveguide to transmit a laser beam from one point to another. Their models help them learn the function of...
