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....

Future chemists practice laboratory techniques by creating a monochloramine solution. The objectives are to use of dilution, 9concentration, and measurement skills and to prepare a solution that will be used in a water treatment...

Students are introduced to how the differences in solubility of materials are used in the manufacture of fibers and films. They are also introduced to the various processes used to make films and fibers. Pupils prepare fibers using wet...

Students are introduced to the analysis of health risks in the laboratory, particularly from vapors from organic solvents. They consider quantitative measure of risk such as threshold limit values (TLVs), the amount of the compound that...

Ecology aces examine sea surface temperature maps and relate temperatures to concentration in fish and zooplankton populations. Take your class to a computer lab and provide experience with actual remote sensing data. Some of the links...

Students demonstrate how to alphabetize animal names. In this word study lesson, students identify animals that live on the farm and conduct a favorite farm animal survey. Students order animal pictures in alphabetical order.

Junior chemists manufacture biodiesel in the lab. In this exercise, they check the purity of the biodiesel using thin layer chromatography. They also calculate its density and heat of combustion. They are sure to rise to the...

Get your head in the clouds before teaching cloud types to your mini-meteorologists. The lesson opens with a beautiful PowerPoint presentation of clouds portrayed in different artists' paintings. After viewing artistic renditions,...

A beautiful tapestry map of North America is examined by geology masters. The map incorporates the topography and geology of different regions. You can purchase printed copies or a large poster of the map, or if you have a computer lab...
