Gravity and Its Effect on Planetary Orbits

Why is the sun round? Examine this question, and others, with your pupils while teaching them how to live in a more earth-friendly environment. Pupils explore Sun composition and discuss how solar wind, sunspots, and solar energy affects...

A well-written lesson plan, second in a series of four, gets high schoolers exploring how the Antarctic food web is impacted by climate change and the associated melting of polar ice sheets. It begins with a PowerPoint presentation about...

Here is the first of four poignant lessons on how humans and oceans interact, even if people live far from the coast. This particular lesson also examines studies that are taking place in Antarctica of how climate change is affecting the...

What do magnetic fields look like? The best way to learn about magnetic fields is to try identifying them for yourself. Scholars will understand the importance of magnetic fields after completing this experiment. The extension activities...

What does your world revolve around? Challenge the class as they learn about orbits and the effects of them on our modern world. Young astronomers begin by measuring ellipses and calculating the eccentricity of Earth's orbit. Then, they...

Make an impact on young physicists with this fun collection of resources. After first watching a video and taking notes on the physics of car crashes, students go on to complete a series of activities that explore the concepts of energy,...

What effects do temperature and carbon dioxide levels have on the zooplankton of Antarctica? This concluding lesson in a short unit on climate change and the ocean helps environmental scientists answer these questions. After learning...

NASA's LCROSS mission is dropping a probe into a lunar crater. Groups design a system to travel down a zip line and drop a marble onto a target in the classroom. The groups then modify their designs based upon testing. 

Open this instructional activity by demonstrating the production of acidic carbon dioxide gas by activated yeast. Emerging ecologists then experiment with seashells to discover the effect of ocean acidification on shelled marine...

This video reviews many of the concepts covered in the regular chemistry playlist. Sal tries to draw and clarify how to visualize the multiple x, y, and z orbitals. He elaborates on probability clouds and the sp3 orbital configuration of...
