Pbs Teachers: Scientific American: Future Car: Fuel Cells

With rising oil prices and increasing concerns over global warming, the pressure is on for engineers to develop alternative sources of energy. Among the new technologies being developed are hydrogen fuel cells, which young scientists...

A fuel cell is where the jailer keeps gas guzzlers. Scholars review chemical reactions, chemical bonds, and chemical structure in order to apply these concepts. Participants construct fuel cell kits, using electrolysis to run the car and...

Explore the fields of engineering and automobile design. Construct from a variety of materials a model of a vehicle that travels the greatest distance on balloon power.

Investigate the scientific principles of biospheres, and observe the effects of biological processes on closed systems.

Explore efforts to return parts of the American prairie using controlled cultivation and grazing. Compare and contrast the effects of various levels of ground shade on new seedlings.

Explore the scientific breakthroughs in understanding the genes that control the way we age. Collect your own samples of active nematodes by assembling and using a device called a Baermann Funnel, then observe the behavior of these worms.

Explore scientific research saying that continued brain activity may delay or slow the loss of memory function. Investigate and practice different techniques to increase recall.

Explore the relationship between pressure and vessel diameter and create a model that represents how elevated blood pressure may affect weakened vessels. Design and critique a repair device.

Explore the vocabulary and vocalizations in chimpanzee communications and connect them to emotions. Develop and participate in a field study of animal behavior based on observations and interactions with dogs

Explore the concept of the calorie. Determine the calories/gram of the burned food by measuring its mass, and make conclusions about the experimental design.
