Spectral Surprise
Students create spectral colors. In this hands-on science lesson, students examine the electromagnetic spectrum as they follow steps to create a model that separates and displays light.
Curated OER
Reflect and Refract
Students explore light. In this properties of light lesson, students define the terms refract, reflect, and diffract after listening to the teacher's description. Students listen to the book Light Magic and observe a spoon in a glass of...

Eclipse Activity Guide
Ever made solar s'mores? Or recreated the solar system using peanuts? Astronomers young and old investigate all things solar using a variety of activities. Explore how the sun works, types of light it emits, and methods of charting the...
Cornell University
Investigating and Modeling Hardness
Model hardness testing with a self-designed hardness test. Young scholars rate the hardness of different types of aspirin using the Vicker's Hardness scale. They then relate hardness to the solubility of each aspirin tablet.
Cornell University
Splitting Water with Electricity
Explore how electricity splits water molecules into hydrogen and oxygen. Learners begin by calculating the voltage necessary to separate the water. They then perform the experiment and measure the ratio of hydrogen and oxygen bubbles.
