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...

Your teenagers may have heard of fracking, but do they really know what it is? And could they debate the benefits and risks? Educate your environmental science class with a lesson plan about hydraulic fracturing, non-renewable...

Young geologists piece together the puzzle of plate tectonics in an earth science lesson. Given a physical map of the world, they search for land formations that indicate the location of different types of plate boundaries.

Not all chemical reactions happen at the same rate because some, like explosions, occur quickly and some, like rusting, occur over time. Here, learners explore chemical reactions and their rates in the 16th lesson of 36. Through readings...

Radioactive pollutants can enter the body through ingestion, inhalation, absorption, or injection. The last lesson in a series of 36 introduces pupils to radioactive pollution. They study its sources, both natural and man-made, its...

Learn about radiation, convection, and conduction with a multiple choice worksheet. Each question prompts kids to decide what is different about each form of heat energy transfer, and what is the same.

Ozone, made of three bonded oxygen atoms, is found 15-30 km above Earth, has a strong smell, is blue, and blocks sunlight from hitting the surface of Earth. The 22nd lesson in a series of 36 specifically focuses on the important elements...

Potassium permanganate, containing manganese one of the transition elements, has many uses such as mouthwash and propelling rockets, making it is a very diverse compound. The lesson delves into such transition elements and...

Young foresters examine the strategies, like prescribed burns and thinning, that are employed to ensure healthy forests.
