Invent a Backscratcher from Everyday Materials
Being able to recognize a problem and design a potential solution is the first step in the development of new and useful products. In this activity, students create a device to get "that pesky itch in the center of your back." Once the idea is thought through, students produce design schematics (sketches). They are given a variety of everyday materials and recyclables, from which they create back-scratching devices.

Design a Parachute
After a discussion about what a parachute is and how it works, students will create a parachute using different materials that they think will work best. The students will test their designs, which will be followed by a class discussion (and possible journal writing) to highlight which paper material worked best.

Learning math : Measurement
This college level course, developed for elementary and middle school teachers, begins with the fundamentals of measurement, then examines standard units in the metric and customary systems. Online workshop sessions cover measurement of a circle, area and volume formulas, angle measurement, and indirect measurement encountered in trigonometry. The final session explores ways to apply these concepts to K-8 classroom teaching. Each of its ten sessions contains video programming, problem-solving ac

Spaghetti Bridge
Civil engineers design and construct structures such as buildings, dams, and bridges. We can explore the field of engineering by making a bridge using spaghetti. This bridge is then tested based on the weight it can carry without breaking.

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

2.14 Summing up
This unit is concerned with macroevolution â€“ 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.

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
