When Things Start Heating Up
Young scholars explore how and why heat is produced from things that give off light, from machines, or when one thing is rubbed against another. They participate in several hands-on activities designed to help them realize that heat is...
Curated OER
Let the Sun Shine!
Students investigate how the sun can be used for energy. They read a handout, discuss the pros and cons of passive solar building design, develop flashcard questions, and identify jobs that can be helped by solar energy.
Curated OER
Riding the Radio Waves
Learners examine the basic concepts of radio waves and magnetic fields. They study how the AM radios are built and demonstrate the concepts of amplitude and frequency.
Curated OER
Solid Waste Takes Over
Students explore solid waste and its effects on the environment. They explain some of the major problems caused by waste disposal and the use of landfills. They suggest ways to reduce the amount of solid waste going into a landfill.
