In this Nature video, watch a battle between a loggerhead turtle and a shark.
This video features the remarkable discovery Jonathan made in 1998 about Basking sharks, the second largest fish on Earth. While diving with Basking sharks in the frigid waters of the Bay of Fundy, Jonathan saw parasitic lampreys on the backs of the sharks. This had never before been documented, so he returned the next year with a shark biologist and a lamprey biologist to attempt to recover living lampreys from the backs of Basking sharks. They didn't think Jonathan could do it. Wait until you see what happens! Please see the accompanying lesson plan for educational objectives, discussion points and classroom activities.
In the warm and blue waters off Hawaii, Oceanic White Tip sharks often follow behind pods of Pilot whales. For the longest time, biologists have had no idea what is going on. Are they eating the whales? Are they stealing food from the whales? In this video of an expedition to follow the sharks and observe them, Jonathan finally figured out what is going on, and you wonŰŞt believe the disgusting truth! Please see the accompanying study guide for educational objectives and discussion points.
In this video segment from Nature, see the value that sharks can have on the tourism industry in an area.
This video features the Thresher shark, which may very well be the strangest looking shark in the world, with a tail almost as long as its body. This shark is very rare, almost never seen by divers...until now. Using advanced diving technology, Jonathan visits a remote reef in the Philippines where Thresher sharks show up every morning to be cleaned by small fish. Please see the accompanying study guide for educational objectives and discussion points.
In this video, filmed thirty miles off the coast of North Carolina, there is a shipwreck on the bottom, 130 feet down. Swarming around the wreck are dozens of Sand Tiger sharks. They look menacing, but they seem to be very docile. What are they all doing there, in one spot? That's what Jonathan wants to find out. Using a variety of filming techniques, Jonathan attempts to discover the secrets of the Sand Tiger shark gatherings at the wrecks, and does the first ever night dive with these shark..talk about scary! Please see the accompanying study guide for educational objectives and discussion points.
This learning activity is a climate change musical for K-12, youth groups or faith organizations. Shine weaves together climate science and performance art into a fun and powerful story, which spans 300 million years of geological time to convey how humanity, energy, and climate are interrelated.
This article, written for students in grades 4-5, introduces the concept of albedo and describes the shrinking of Arctic sea ice. Modified versions are available for students in younger grades.
In this adapted ZOOM video segment, cast members calculate how much water they each use during a typical shower. They compare their results to their original predictions.
This video features scientists in New Zealand's Southern Alps, examining samples from the rocky landscape once dominated by glaciers. Their research, combined with other climate records, has revealed a link between glacial retreat and rising levels of carbon dioxide in the air.
An interactive lecture that uses flash animations showing the researcher and their experiments that were used to develop the basic concepts in Mendelian genetics. Includes multiple choice questions students can answer in class.
The purpose of this resource is to investigate the center pixel of a homogeneous land Cover Site in order to understand that individual land areas are part of a larger land system.
The purpose of this resource is to investigate the idea that every dynamic system has energy and matter in different forms.
In this field investigation, students will identify and determine the population size of snails in an aquatic environment.
This video segment adapted from NOVA/FRONTLINE looks at American energy consumption and the resulting production of greenhouse gases.
This is an interactive map of California and the Sierra Nevada mountains, showing how the amount of water stored in the snowpack will vary under different climate scenarios. The tool shows observations and projections from 1950 to 2090, and uses low or high emission scenarios to model future snowpack. The tool can be adjusted to show different months of the year and various climate models, graphed by site.
In this video from DragonflyTV, follow the investigation of Isaac and Anjali as they record, measure, and analyze data about how the Sun's position in the sky affects a solar-powered car's speed.
This introductory video summarizes the process of generating solar electricity from photovoltaic and concentrating (thermal) solar power technologies.
In this 'Energy Education for the 21st Century' design challenge, students construct and evaluate a solar-powered model car. Students utilize the design process and undergo review by their peers to select an optimal gear ratio and components for their car. As a culminating activity, students compete in a Solar Sprint race modeled after the National Renewable Energy Laboratory's Junior Solar Sprint competition.
In this video segment adapted from ZOOM, cast members assemble a solar still and make fresh water from saltwater, demonstrating two steps of the water cycle, evaporation and condensation.
