The Energy of the Sun

Middle school science stars observe and record data on the solar radiation reflected off or transmitted through various materials. They predict properties for various materials, and test their predictions by touch. This instructional...

Are you nuts? An engaging experiment burns nuts to find their kilocalories. Young chemists analyze at least two different types of nuts with their experimental results versus what is on the package. The resource offers a great lab for...

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...

Everything around you is related to chemistry and more specifically, the energy within a system. The video explores how energy, in its different forms, changes after conversion — given off as heat or absorbed as heat  in chemical...

There may be nothing new under the sun, but astrophysicists constantly are learning new things about the sun! In this minute-long clip, learn the physics of fusion in the sun and the possibility that quantum tunneling is happening...

Need to take your teaching of energy concepts to another level? Check out a strategic video that examines standard PS3D in the Next Generation Science Standards. Filled with examples, scenarios, and connections to the life sciences, the...

If renewable energy sources are the best option, why aren't they used on a global scale? Junior environmentalists explore the benefits and problems associated with energy sources such as solar, wind, and biomass with a short video and...

Free energy, get your free energy here! Learners see that all organisms require free energy, which comes from the sun. The lesson explains the first two laws of thermodynamics and then analyzes metabolism, via glycolysis, on a very...

Explore the center of gravity with your science class as they create a deadfall trap with common materials. They research the concepts of energy conservation and gravitational force before dividing into small groups to create a model of...

When asked to list everyday objects that require energy, most people list technology that use batteries or electricity. Through hands-on exploration, young scientists discover energy is much more than just circuitry. They play with...
