MICROSCOPIC SAFARI PART 1: Shan is going on a safari in a fresh water pond and Mr. Wizard shows her a supply of tools she is going to use to gather and inspect her catches. He also gives her a small transparent tank, a microscope, and books with descriptions of what she might find. GAS PRESSURE AND TEMPERATURE: Mr. Wizard rubs alcohol on Giselle’s hand. She notes that it feel cool. The faster moving molecules absorb heat from her hand as they evaporate. Mr. Wizard explains what serves the same purpose to keep her cool. He also explains heat absorption. WHITE TAIL DEER: If you have ever seen a wild deer, chances are it was a white tailed or Virginia deer, the most common wild animal in North America. Mr. Wizard explains where the name from. CANTILEVERED BOOKS: Tyler is going to support a book in what looks like a position beyond its support. Mr. Wizard shows him how to move the top book so that it is about to fall and then move it back slightly. He does the same with the second book. Tyler takes over and by the time he has positioned the fifth book, the top book is definitely beyond the edge of the sixth and seventh book on the desk. COLLAPSE SODA BOTTLE: A famous demonstration in which a gallon metal can filled with steam collapses when it is cooled is described by Mr. Wizard. They are going to do a similar stunt with a plastic bottle using only hot water. MICROSCOPIC SAFARI: Shan has returned with the small aquarium in which there is a supply of pond life. She has included several small fish, a caddis fly larva, water beetles, and water plants. LONGER THAN TALL: Erin is doubtful that she is longer than she is tall in spite of the fact that Mr. Wizard claims she is. Mr Wizard explains the scientific reason for this and does a demonstration. NORTHERN LIGHTS: One of nature’s most spectacular displays is the Aurora Borealis. The sky over the poles glows red, white and green when particles spewed out by the Sun are captured by the Earth’s magnetic field and collide with the gases in the upper atmosphere. COORDINATED SYSTEMS: With an instant camera, Mr. Wizard takes a picture of Damon. He then challenges Damon to find an example of the fourth dimension on the desk on which are a ruler, piece of string, notebook, map, box of sugar cubes, measuring glass, toy refrigerator, and a record turntable. Mr. Wizard explains.
