Wave goodbye to the same old demonstrations for alternative energy sources, and wave hello to this one investigating ocean waves! Using a water bottle to create an oscillating water column, learners see and possibly hear how the...

Rise and shine! Class members collaborate to construct a photovoltaic solar cell with two semiconductor layers, as guided by this fabulous lab sheet. They test its output with an ammeter or galvanometer. 

Let there be light. The last installment of a seven-part series has pupils conduct an experiment on light attenuation through different numbers of transparency sheets. They then relate the results back to how X-rays measure bone density.

Who knew that a possible answer to Earth's energy resource problems was lurking deep beneath the ocean's surface? Part four of a six-part series introduces Earth Science pupils to methane hydrate, a waste product of methanogens. After...

Whether you want to heat things up in science class or cool things down a bit, an intriguing lab's got you covered! Science scholars explore the principles of thermodynamics using a solar oven, then change the conditions to turn their...

Upper graders form a "Presidential Task Force," and attempt to make recommendations concerning the future of the national power grid. After a teacher-led discussion which proves that our nation's energy consumption will soon outpace our...

Help your class become laser focused on the connection between sound and light. Scholars set up mirrors to bend and direct lasers that are connected to a music source. Music should start playing when the laser hits the photoresistor.

Warm up to the idea of solar energy. A lesson includes three activities that challenge scholars to apply knowledge in new ways. First, they learn to run an alarm clock without a battery by using solar energy. Next, they complete an...

Write, edit, and then revise! The fourth lesson plan in a five-part series asks peers to provide feedback on research. Individuals then use the research to edit and revise conclusions and develop their presentations.
