Isolation of Phytochrome
Why do soybean plants that are planted weeks apart in the spring mature simultaneously in the fall? Four independent activities cover the history of phytochrome research, scientist collaboration, the electromagnetic spectrum, and...
Cornell University
Insect Anatomy
Young entomologists discover insect anatomy in a very detailed unit plan. Offering background information for teachers about various insects, class members explore the differences between bugs and insects—and yes, there are many...

Bronx Cheer Bulb
If you chew or make a "raspberry" while viewing an LED light source, the light will appear to wiggle or flicker. It is not because of the light itself, but because of the vibration of your skull! Have your physics class give this a try...
Curated OER
Understanding Waves
Students examine the physical properties of waves to explore the word crest and trough. They use toys to study waves in air, water and light.

The Effects of Photosynthesis on Plant Growth
Students examine the process of photosynthesis; its products and reactants, and the sequence of the process. They diagram the light reactions, record observations of plants, and discuss how difficult it is to measure plant growth as it...

Marine Fisheries Management
Almost 200 slides make this a vast collection! It is a quirky collection, titled "Marine Fisheries Management," but having little to do with that occupation. What you will find are two-toned blue backgrounds with no pictures, but a few...
Exploratorium
Short Circuit
Though not commonly searched for, this is a vivid demonstration of how a fuse can be blown, or rather, how resistance works in an electric circuit. You will basically set up a circuit with no lights or bells or motors, allowing the wire...
Curated OER
Prairie Plant Investigation
Students carefully observe prairie plants and record their observations in a science journal. They examine the root systems of grasses and flowers and surmise how these plants can grow together on the prairie.
