Curated OER
Exploring Infrared Image Technology
Students view infrared images of a blowing hair dryer, a Popsicle, and a toaster. They discuss the images and ways they are different than visible light images. Students view a temperature scale and discuss which parts of the item are...
Curated OER
The Sounds of Summer
Students experiment with measuring the speed of sound in an open field by clapping hands and measuring the time delay between the clap and hearing the sound at a long distance. Students practice solving equations at completion of activity.

TE Activity: Ohm's Law 2
High schoolers study Ohm's Law 2 after completing an activity about Ohm's Law 1. They determine how long it takes to charge a battery. They examine if it is better to use batteries in series or parallel circuits.
Curated OER
Growing Corn
Sixth graders create a Venn diagram of different soil types. They plant cord seeds in clay, sand, and fertile black soils are record their growing rates. After two weeks they discuss the effects of soil types on the growth process.

Fish Tank Optics: Learning How Light Travels
Students examine light waves and see how they travel. They explain that light moves in waves, which can bounce off of or go through materials. They use a flashlight to shine on a variety of objects.
Curated OER
Lenses and Mirrors
Students investigate lenses and mirrors showing how they bend and reflect light waves.
Curated OER
Heat Currents
Students using a slide made out of aluminum foil and pin holes observe visible light.

Analytical Spectroscope
Students using a spectroscope view different substances when heated with electricity.
Curated OER
Water Prism
Students using a glass prism filled with water are able to see all of the visible colors found the sunlight.
Curated OER
Understanding Waves
Students perform 3 hands-on activities to help them explain the terms "crest" and "trough" as related to sound, water, and light waves. All three waves types have troughs and crests. The activities use toys to demonstrate the properties...
Curated OER
Light Waves and Spectroscopes
Students observe continuous and bright line spectra through a simple, inexpensive spectroscope that is suitable for classroom use and work through typical student laboratory exercises.
