University of Iowa : burn oat hulls for economic, environmental benefit
What is an alternative energy source that is available today? This article, part of a series about the future of energy, introduces students to a pilot project of burning oat hulls at the University of Iowa power plant. Students read that the burning of oak hulls instead of coal provides for cleaner air and additional space in landfills. Copyright 2005 Eisenhower National Clearinghouse

Observe a visual model of Earth's spheres
This Earth science resource enables students to view Earth's four spheres--the geosphere, hydrosphere, biosphere, and atmosphere. The visualization is introduced by a paragraph that defines the four spheres. Below the paragraph, there is an image of a globe that a viewer can animate by clicking on it. The globe separates into four globes, each of which shows one sphere and is labeled with the appropriate sphere name. The animation contains a legend to explain the color coding used. Controls allo

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

2.14 Summing up
This unit is concerned with macroevolution – the patterns and processes of evolution above the species level. A crucial consideration in macroevolutionary studies is that of the evolutionary relationships (phylogeny) of the organisms in question. The unit begins with an introduction to the scope of macroevolutionary studies and illustrates methods of reconstructing phylogeny, from both morphological and molecular data.

The Squeeze is On
Students will learn about the force of compression and how it acts on structural components through a hands-on group project. Using everyday products such as paper, toothpicks, and tape they will construct a structure that will support the weight of a cinder block for 30 sec.

Lights Out!
This lesson introduces the concept of electricity by asking students to imagine what their life would be like without electricity. Two main forms of electricity, static and current, are introduced. Students learn that electrons can move between atoms, leaving atoms in a charged state.

Learn to Build a Rocket in 5 Days or Your Money Back
In this lesson, students discover the entire process that goes into designing a rocket for any customer. In prior lessons, students learned how rockets work, but now they learn what real-world decisions engineers have to make when designing and building a rocket. They learn about important factors such as supplies, ethics, deadlines and budgets. Also, students learn about the Engineering process, and recognize that the first design is almost never the final design. Re-Engineering is a critical s

A New Angle on PV Efficiency
Students examine how the orientation of a photovoltaic (PV) panel relative to the sun affects the efficiency of the panel. Using sunshine (or a lamp) and a small PV panel connected to a digital multimeter, students vary the angle of the solar panel, record the resulting current output on a worksheet, and plot their experimental results.

Rube Goldberg and the Meaning of Machines
Simple and compound machines are designed to make work easier. When we encounter a machine that does not fit this understanding, the so-called machine seems absurd. In this lesson, the cartoons of Rube Goldberg are introduced and engage the students in critical thinking about the way his inventions make a simple task even harder to complete. As the final lesson in the simple machines unit, the study of Rube Goldberg machines can help students evaluate the importance and usefulness of the many ma

Sliding and Stuttering
Students use a spring scale to drag an object such as a ceramic coffee cup along a table top or the floor. The spring scale allows them to measure the frictional force that exists between the moving cup and the surface it slides on. By modifying the bottom surface of the cup, students can find out what kinds of surfaces generate more or less friction.

Balsa Glider Competition
The purpose of this activity is to bring together the students’ knowledge of engineering and airplanes and the creation of a glider model to determine how each modification affects the flight. The students will use a design procedure whereby one variable is changed and all the others are kept constant.
