WALKING IN CIRCLES - Mr. Wizard tells Lorilee that people lost in the wilderness have a tendency to walk in a circle. They are going to find out if it’s true. He blindfolds her and asks her to walk to a marked tree. He stops her near the tree and removes the blindfold. She is surprised to see how far away the tree is. They repeat the test and she again is the same distance away. STEEL WOOL TEST - On a double pan balance are two pads of steel wool. The balance has been adjusted so that both sides are equal. When the pad on one side is heated with a torch, will the pad get lighter, stay at the same weight or get heavier? Erin thinks it will get heavier. As they heat the pad, she sees bits of something falling from it, changes her mind, and assumes it will get lighter. When she places it back on the balance, it is slightly heavier than before. Heat speeded up the combining of the steel wool and oxygen in the air. Instead of just the steel wool, the pad now has a supply of iron oxide which makes it heavier. ENGINEERING EXAM – Mr.Wizard narrates: Although it looks like fun and games, this is a final exam for engineering students at the Univer­sity of Maine. When students have graduated, they’ll face problems that can’t be learned in the classroom. That’s one of the reasons the University of Maine has the amphibious human-powered com­petition. Students learn what it’s like to turn an idea into a final product. A FAN IN SLOW MOTION - A three-bladed fan illuminated in ordinary light spins much too fast to be studied. When illuminated by a light flashing 60 times a second, the speed of the fan can be controlled until it appears to be stopped. 3D MAGNET - Tarek’s hand is on top of a small box and Mr. Wizard is sprinkling iron filings on it. It looks like black moss is growing on his hand. Tarek removes his hand and picks up the box to see a very large horseshoe magnet. Mr. Wizard put a steel hammer on it and asks Tarek to remove it. He does so, but with great difficulty because of the strength of the magnet. Tarek shakes up a transparent box containing iron filings and mineral oil. When Mr. Wizard add a magnet to the center of the box, they see the magnet lines of force in three dimensions. TREE BRANCH COVER PART 1 - Mr.Wizard has tied a large plastic bag around a branch of a small tree. He explains to Alan that leaves give off moisture and they are going to collect it. SUPERMARKET BATTERIES - Mr.Wizard shows Eliana how to get a battery type current by using a can of sauerkraut, wire, & a meter. MEDICINE YOU WEAR - Mr.Wizard explains there are medicines you wear. It will deliver medicine to the heart by diffusing through a spe­cial membrane into his skin then into his bloodstream and onto his heart. So far, only a few medicines can be taken by wearing them. TREE BRANCH COVER PART 2 - Alan and Mr. Wizard approach the tree branch covered with transparent plastic to see the surprising amount of water given off by the leaves. LEECHES – Mr.Wizard narrates: This is a leech often called a blood sucker. It’s not a rare animal but it is rather unusual. It has, in effect, a series of brains. The study of leeches is instrumental in the study of humans because they have complex brains. HYDROGEN REACTION – Mr.Wizard explains that this experiment should always be performed with safety glasses and with a responsible adult! Erin and Mr. Wizard are at some distance from the counter on which is a cylinder. Suddenly, there is a loud explosion. The cylinder is shot off the counter. The cylinder was filled with hydrogen gas which was lighted at a hole in the top of the cylinder. At the bottom is another hole through which air can enter. When just the right mixture of hydrogen and oxygen occurs, they combine with an explosion to produces a very tiny drop of water: H2O.
