Ecological Footprint: Overshoot
In this two-minute sound segment, the director of the Sustainability Program for the public policy group Redefining Progress discusses the concept of your ecological footprint. This is the amount of nature it takes to support your lifestyle. He says that if we use more than can be replaced by nature we are in a condition called overshoot. He suggests that this can continue for a while but eventually someone will have to pay with a lower standard of living. This site is from an archive of a daily

Seed Dispersal 101
This two-minute radio program introduces listeners to the variety of agents that disperse seeds. The program's guest, a plant biologist, cites examples of nonliving and living dispersal agents that include the wind, water, and such animals as birds and bats. He also explains that a plant's fruits or seeds often offer clues about how they are dispersed. The program, which is available here in audio and text, is the first in a series about seed dispersal.

Art of the Tetrahedron
Any four points in space that are not all on the same plane mark the corners of four triangles. The triangles in turn are the faces of a tetrahedron. It's the simplest of all polyhedra--solids bounded by polygons... To sculptor Arthur Silverman of New Orleans, however, tetrahedra are very special. He has been investigating variations of tetrahedral forms for more than 20 years in sculptures displayed in public spaces in New Orleans and other cities from Florida to California.

Examine evidence of Earth turning about an axis
Using an animation of the classic pendulum experiment, this resource supplies middle and high school students with evidence of the Earth's rotation on its axis. The introduction explains that although pendulums are known to swing in a fixed path, on Earth their path appears to shift over time. As the animation reveals, it is not the pendulum's swing that changes--it is the Earth beneath the pendulum that moves. The animation contains three screens: two with different views of a pendulum swinging

Musical Images
Students are introduced to the concept of the image of music. After listening to a song, they draw images of a it by deciding where different musical instruments were placed during recording. They further investigate audio engineering by modeling the position of microphones over a drum set to create a desired musical image.

What Floats Your Boat?
Students use modeling clay, a material that is denser than water and thus ordinarily sinks in water, to discover the principle of buoyancy. They begin by designing and building boats out of clay that will float in water, and then refine their designs so that their boats will carry as great a load (metal washers) as possible. Building a clay boat to hold as much weight as possible is an engineering design problem. Next, they compare amount of water displaced by a lump of clay that sinks to the am

All Caught Up: Bycatching and Design
Bycatch, the unintended capture of animals in commercial fishing gear, is one of the hottest topics in marine conservation today. About 25% of the entire global catch is bycatch. This surprisingly high level of bycatch is responsible for the decline of hundreds of thousands of dolphins, whales, porpoises, seabirds and sea turtles each year. Through this curricular unit, students will analyze the significance of bycatch in the global ecosystem and propose solutions to help reduce bycatch. Student

Do Plants Eat?
Through a teacher-led discussion, students realize that the food energy plants obtain comes from sunlight via the plant process of photosynthesis. They learn what photosynthesis is, at an age-appropriate level of detail and vocabulary, and then begin to question how we know that photosynthesis occurs, if we can’t see it happening. Elodea is a common water plant that students can use to directly observe evidence of photosynthesis. When Elodea is placed in a glass beaker near a good light source

Cellular Respiration and Population Growth
Two lessons and their associated activities explore cellular respiration and population growth in yeasts. Yeast cells are readily obtained and behave predictably, so they are very appropriate to use in middle school classrooms. In the first lesson, students are introduced to yeast respiration through its role in the production of bread and alcoholic beverages. A discussion of the effects of alcohol on the human body is used both as an attention-getting device, and as a means to convey important

The Growling Stomach
In this lesson, the students will investigate what types of plants and insects they could eat to survive in the Amazon. They will research various plants and/or insects and identify characteristics that make them edible or useful for the trip. The students will create posters and present their findings to the class.

D-Day Invasion of Europe (2:01)
On June 6, 1944, Allied troops storm the beaches of Normandy in the largest amphibious assault in history. This is a good video that explains what happens on this day and has excellent graphics and clear explanations. A map of the area would be of benefit.
