WATER INTO UPSIDE DOWN GLASS: Darren fills a kitchen syringe with water from an aquarium. The syringe has a bent tube at the end. Mr. Wizard challenges him to use it to fill an inverted drinking glass that has some water in it. OSCILLOSCOPE - RADIO WAVES: Mr. Wizard shows Leila an oscilloscope. She defines oscillate: to move back and forth and scope: to see. They are going to use the oscilloscope to find out how radio works. She knows only that she moves a dial to tune into a station. Mr. Wizard explains. CUBES - OPEN UP QUIZ: Mr. Wizard shows Laurie several forms that she has to determine if they will fold up into cubes. COOKIES: The physical and chemical changes that occur when cookies are heated are discussed. DOWEL THROUGH BLOCK: Mr. Wizard and Christian discuss the role of inertia with the ways to put a new head on a hammer. BLACK BEARS OF MAINE: This black bear cub was found abandoned and was reported to the Inland Fisheries Wildlife Department of the State of Maine. After an examination, such orphans would usually be turned over to a zoo but not this cub. He'll be placed with a new mother bear as part of an unusual program for bear research. METAL DETECTOR: Mr. Wizard explains to Darren that the battery in a metal detector can be adjusted to balance two coils in the apparatus. When the coil that sends a wave into the ground encounters a bit of metal, it goes out of balance and a signal is generated.
