How Does Energy Change?

The sun sends the earth 35,000 times the amount of energy required by all of us on the entire planet, every day. The fourth lesson plan in the 10-part series looks at how light energy from the sun transfers into thermal energy. Scholars...

Only 10 percent of an incandescent bulb's energy is used to create light; the remaining 90 percent is heat. In the unit of activities, young chemists examine energy through hands-on activities, videos, discussions, and readings. Scholars...

In this energy changes activity, students solve 5 problems using the formulas for potential and kinetic energy related to baseball energy, coasting rocket energy and the energy of falling stones.

Is wildlife affected the same way by different electricity generation methods? Teams work together to research four electricity generation sources and their impacts on wildlife. The teams create a summary report and share their findings. 

How does climate change affect you? First in a three-part series, the activity focuses on how individuals living around the world are affected by climate change. Individuals take on the role of a given character and share their...

Sal introduces students to Hess's Law. The law states that the energy change of a process is independent of how we get from one state to another. He sets up a series of reactions, and solves them to illustrate the principles behind...

A lively narrator talks about how solar energy can be converted into electricity. Brightly-colored animations and diagrams along with short video clips make this an appealing presentation. Use it as an introduction to solar power with...

What makes a clock tick or a bulb light up? The concept of work is explained to a backdrop of clever animation. Physics fans learn that the amount of work equals the product of the force and distance, and that the rate equals the amount...

Address the question that physics learners are burning to know the answer to: How does an atom-smashing particle accelerator work? The LHC or Large Hadron Collider is introduced as a tool for uncovering the mysterious rules that govern...
