What are Alternative Fuels? -- Gas Laws in Action/Propane Investigation

Using helium as an example of propane, physical science middle schoolers experiment with and graph the relationship between temperature and volume in gases. In a whole-class demonstration, they show how molecules behave under different...

More than a week's worth of investigation is provided in this source. Physical science stars experiment to describe specific heat, conduction, convection, and radiation. They also discover the relationship between mechanical and thermal...

Teams of Texas tourists gather into groups to analyze what they can do with $50 worth of an alternative fuel. They write checks, keep a balance sheet, and map out their sight-seeing route taking into consideration the location of...

Physical science learners conduct a simple experiment using the heat of their hands to affect the fluid pressure. They place a balloon atop a freezing cold bottle and observe what occurs as it warms up. Both activities demonstrate how...

Brief, but beneficial, this little gem displays the workings of a hydrogen fuel cell. A simple black-line diagram has question marks at the input and the output, as well as in the middle of the cell. Click on each question mark to reveal...

All types of energy are presented here, with neat pictures and labels to illustrate the technology typically used. Ways of harnessing the energy most efficiently are discussed, and good examples provide starters for further research....

This PowerPoint is a gem! Seventy-eight slides present an entire introduction to matter in bullet-point fashion. Viewers learn about everything from mass and inertia to phase changes and gas laws! The only glitch is that the links to...

Although the title is States of Matter, this presentation is a collection of 4 slides just dealing with gas particle behavior, pressure and the Laws of Boyles and Charles and Gay-Lussac.

Wow! Colorful and simple, these 160 slides introduce the various forms of energy, along with a relevant image. Some of the images are animations, which help beginning physical scientists to visualize the flow of electrons or energy! This...

Slide books with a little assistance from Newton. Using books, groups create a demonstration of Newton's Second Law of motion. Pupils compare the distance traveled by one and two books when they apply a force to them.
