Larger groups will be divided and the demo will be conducted twice. This one is a really cool demonstration. Experiments include how liquid nitrogen would affect the gas in a human lung versus that in an alien lung as well as effects on materials used in spacecraft design. Students experience a rainbow of colors as they learn about the electromagnetic spectrum. Diffraction gratings are used to view both continuous and bright-line spectra.
Laser light is compared and contrasted with ordinary white light.
The basic principles of operation of a laser as well as safety issues and laser research applications are discussed. The cerebrum, the temporal, parietal and occipital lobes, and the cranial nerves are identified using an actual human brain as well as a model. Techniques used to map functioning areas of the brain are discussed. Larger groups will be divided and the demo will be conducted twice. This demonstration provides an uplifting moment.
