Learn about thermal energy, also known as heat or heat energy, and the ways in which it can move from one object to another,

This video segment, adapted from NOVA, describes the energy flow in a coral reef, including its food web. [3:48]

Scientists study ice sheets because they influence weather and climate, playing a role in atmospheric and ocean circulation. Ice sheets can also have huge impacts on global sea levels because they store so much water. Explore this...

Here is a nifty worksheet on energy transfer. Physics fanatics analyze a diagram and state whether or not friction is involved. They sketch bar graphs and draw energy flow diagrams for each system as well. Circular motion, movement up...

Produce, consume, decompose...repeat! Examine how matter and energy cycles in ecosystems by watching a video discussing NGSS standard LS2B. The narrator explains the requirements of the standard at each grade level, plus gives tips to...

An interactive activity that discusses how radiation is like energy and comes in different forms.

The Arctic plays an important role in regulating Earth's climate. The region reflects much of the Sun's energy and helps keep the planet cool. Data collected by NASA have revealed that sea ice in the Arctic has steadily declined over the...

Examine this visualization by NASA to understand how the warming of the Arctic region has caused the sea ice extent to decline by 40%, thereby throwing our earth's energy budget off balance. Extensive resources included are teaching...

This video segment adapted from NASA's Goddard Space Flight Center explains how and where hurricanes develop. Learn how El Nino events alter the course of atmospheric circulation. Includes background reading material and discussion...

Students learn about the giant impact hypothesis for the Moon's formation, and how the Apollo Moon rocks have contributed to scientists' understanding of the Moon.
