In this media-rich lesson, students learn how global warming is changing the Alaskan environment and examine the consequences of climate change on the region's human and wildlife inhabitants.
This video, adapted from NASA, presents rare experimental evidence from the Fermi Gamma-ray Space Telescope supporting Einstein's prediction that space-time is smooth.
Students model, build, and draw diagrams of electric circuits and test the conductivity of a variety of materials.
In this animation produced by WGBH and Digizyme, Inc., see how molecules of DNA are separated using gel electrophoresis, and how this process enables scientists to compare the molecular variations of two or more DNA samples.
Scientists discuss whether or not endocrine disrupting chemicals, which may cause birth defects and other health concerns, should be controlled in the absence of conclusive proof, in this video segment adapted from FRONTLINE: Fooling with Nature.
Watch students as they conduct an energy audit on a home and gain hands-on experience for a career in the green energy industry, in this video adapted from ATETV.
This feature, adapted from Interactive NOVA: "Earth," follows the path of energy as it is transferred via the food chain from one type of organism to another.
This video segment, adapted from NOVA, describes the energy flow in a coral reef, including its food web.
In this lesson designed to enhance literacy skills, students examine energy forms in moving objects and discover how changes from one form to another move cars through a roller coaster ride.
On NOVA, a team of carpenters, timber framers, engineers, and historians recreate a medieval throwing machine called a trebuchet. This adapted video segment explores how understanding energy transfer informs their design.
See potential energy convert to kinetic energy in this interactive activity from WGBH that shows a roller coaster in action.
In this video segment from NASA, robotics researcher Ayanna Howard uses engineering to improve the intelligence of robots in space exploration.
In this video segment adapted from NOVA scienceNOW, learn how what you eat, drink, or smoke may affect the instructions your epigenomes send to your genes, and as a result, change how your DNA is expressed.
In this media-rich lesson, students explore some of the ethical, legal, and social issues related to personal genetic testing and genome sequencing.
In this video excerpt from NOVA, learn about the advantages, disadvantages, and ethical implications of preimplantation genetic diagnosis, or PGD, a technique used to screen embryos created through in vitro fertilization for diseases.
In this NASA video, scientists describe how the Extreme Ultraviolet Variability Experiment will sample and track the Sun's ultraviolet irradiance, providing a detailed time sequence of extreme ultraviolet output -- data that can provide advance warning for potentially disruptive energy bursts.
In this adapted video segment, ZOOM guest Tommy takes us on a tour of the Florida Everglades. He describes what makes a wetland biome unique, including the soil, precipitation, and biodiversity.
How much radiation are we exposed to every day? Find out in this video segment adapted from FRONTLINE.
This video segment adapted from NOVA tells the story of two scientists who inadvertently discovered microwave radiation that is now believed to be heat left over from the Big Bang.
This video segment from Evolution: "Darwin's Dangerous Idea" illustrates the remarkable camouflage of a praying mantis against its leafy backdrop.
