The Engineering Place: Fuel Cell Experimentation [Pdf]

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...

There is a specific zone, or distance from a star, that a planet must be in order to have water in a liquid form. The activity demonstrates how flux density depends on its distance from the source. A photovoltaic cell gets power to...

Take young scientists on a trip through the water cycle with this interactive science activity. After setting up a series of ten stations representing the different places water can be found, children use the included printable dice...

Biotech engineers discover that changes in the DNA code for cell wall formation can help create crops better suited for biofuel production. They extract DNA from wheat germ. They decode paper strips with codes and relate the activity to...

Sure, you may be able to build a better mousetrap, but what about a gum dispenser? In a fun engineering challenge, teams must design and build a working interactive gumball machine with specific constraints and criteria.

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...

Investigate the innovations surrounding fuel cell technology and the potential use of hydrogen as an automobile power source. Generate hydrogen gas by splitting water in a process called electrolysis.

A lesson and activity sheet on buoyancy. Students add weight to a helium-filled balloon to keep it suspended so that it won't float or sink, but instead will 'flink.'

Help young biologists piece together an understanding of cell structure with a comprehensive review worksheet. Tasking students with describing the function of the organelles found in cells and their relationship with one another,...
