In this body fat measurement worksheet, students will conduct an experiment to determine how the "under-water weighing" technique of measuring body fat works. Once the experiment is complete, students will complete 1 short answer question.

Students work in small groups and use a hand-held vacuum pump with a balloon under the dome with some air. Another deflated balloon is attached to the end where the air goes out. As the air is drawn out of the dome the first balloon with...

Students explore practical problems that are related to scuba diving.  In this oxygen lesson students complete a lab activity. 

Students conduct a series of activity that demonstrates Charles' and Boyle's Law. In this chemistry lesson, students determine the relationship among pressure, volume and temperature. They solve problems using mathematical equation.

Students use funnels to put the five solid materials into clear bottles with caps. They observe how the particulate materials look, sound, and move when they shake and roll the bottle. Finally, students write "sound and touch" poetry.

Young scholars assess the environmental impact of their transportation choices. They keep a transportation journal and use a website to calculate vehicle emissions for themselves and their class. They evaluate their transportation choices.

Students investigate the different type of architectural designs for fireplaces. They participate in a discussion that starts with several key questions. The lesson progresses and students complete the worksheet accompanying the lesson.

Students identify the advantages and disadvantages of wind farms and turbines. They examine how weather conditions can affect their effectiveness and how engineers are trying to solve the problem. They discover how engineers use this...

In this English worksheet, students read "International Car Free Day," and then respond to 47 fill in the blank, 7 short answer, 20 matching, and 8 true or false questions about the selection.

High schoolers explore corals and polyps.  In this coral reef lesson students divide into groups and prepare a written report. 

Explore the thermal behavior of gases, in particular, examine the characteristics of atoms and molecules that compose gases. Learn about the ideal law of gases in terms of molecules and moles. Multiple formulas and examples are provided.

The behavior of gases near room temperature and 1 atm pressure can be described using four main properties: amount, pressure, volume, and temperature. In this simulation the mass, pressure and temperature can be varied.

The ideal gas law is an empirical law; it's a relationship between the pressure in a system of gases to the volume, the temperature, and the number of gas atoms/molecules in the system. This "law" is valid if the gas atoms/molecules are...

The ideal gas law is presented and explained. The derivation of other gas laws is performed. Gas behavior is explained in terms of gas laws. Excellent graphics.

This lesson introduces students to the important concept of density. The focus is on the more easily understood densities of solids, but students can also explore the densities of liquids and gases. Students devise methods to determine...

Through this curricular unit, students are introduced to the important concept of density. The focus is on the more easily understood densities of solids, but students may also explore the densities of liquids and gases. Students devise...

This interactive brainteaser from the NOVA: "Voyage of Doom" Web site challenges you to explain the behavior of a helium-filled balloon in a moving car.
