There has been a huge solar energy spill! Let's go outside to play in it. This lesson includes multiple experiments showcasing solar and wind energies. Scholars build a solar heater and an anemometer before testing the results. The...

Emerging biochemists more fully understand the flow of energy in ecosystems as they explore the laws of thermodynamics and relate them to energy transfer in food chains. They also investigate heat loss from the human body and how...

What is biogas and how is it made? After examining background information about the sources of biogas and biogas generators, class members follow the provided information and build a biogas generator that can be used in the...

Here is part two of a two-part lesson in which scholars investigate the changing states of water—liquid, solid, and gas—and how energy from heat changes its molecules. With grand conversation, two demonstrations, and one hands-on...

Through watching several classic air pressure demonstrations, middle schoolers determine that high pressure areas move toward lower pressure areas, heated air causes a drop in pressure, and forces exist when pressures are unequal....

No need to be involved in a home economics or cooking courses to take advantage of this resource. Not only is there an explanation for how microwaves work but there are also tips for how to use the microwave, and cautions...

Did the image I drew match the image you saw? By simulating a satellite and a ground station, teams of two transmit data in the form of pixels in order to recreate an image. They use four different levels of brightness, creating slightly...
