MEANING OF WORDS - Mr. Wizard asks Sarah to define a chair. She says it is something to sit on. Mr. Wizard mentions a bed, sofa, and stool all of which Sarah says are not chairs for one reason or another. Mr. Wizard explains they are going to investigate the science of the meaning of words or semantics because the study has produced some rules she should know about because she uses words all the time. MECHANICAL HEAT - Mr. Wizard drops a plastic bag of lead shot onto the table and explains to Tarek that according to scientific theory, some of the energy is changed to heat when it hits the table. They are going to see if the theory is correct by pouring lead shot into a long tube and closing one end with a cap contain­ing the probe of an electronic thermometer. Mr. Wizard continues to turn the tube upside down as Tarek reads the temperature. He notes that it continues to rise as the lead shot falls which confirms the scientific theory. MICROWAVE PLAT DRIER - Brian has dried plants before, so he knows how to mount a specimen. Mr. Wizard gives him a section of a fern to put between two sheets of paper towel and two sheets of glass. Brian puts them into the microwave oven along with a small beaker of water. The microwave acts to speed up the drying time. FOUCAULT PENDULUM - Kellie does not know what a pendulum is and Mr. Wizard uses the pendulum of a grandfather clock as an example of a weight that swings back and forth. He has a pendulum mounted over a turntable (representing the Earth) on which are the points of the compass. He starts the pendulum swinging over the east/west plane and slowly turns the turntable. Kellie sees that the pendulum continues in the same plane while the Earth moves under it. In 6 hours the pendulum is swinging over the north/south plane. In 24 hours the pendulum is back over the eastwest plane. Mr. Wizard identifies this as a Foucault pendulum named after the scientist who devised it. SONGBIRD STUDY - This voice print was made by a rather unusual voice. Listen as you hear the song of a male white crown sparrow. Mr.Wizard narrates: Dr.Myron Baker of Colorado State University is studying how song birds communicate. In one experiment, he places a fe­male white crowned sparrow into a test chamber. Watch what she does when she hears the recorded song of a male white crown sparrow. DRY ICE COLOR CHANGE - Clara puts pieces of dry ice into a tall transparent cylinder in which there is a dark blue liquid. Bubbles of carbon dioxide gas rise through the liquid. Mr.Wizard explains the liquid has a universal indicator dissolved in it. Clara has used litmus paper which turned from red to blue when exposed to ammonia. The blue liquid in the cylinder indicates that the liquid is an alkali. As the carbon dioxide is dissolves in the water, it will become less alkali and more acid. The color will gradually change when this occurs. As Clara adds more dry ice, the liquid finally becomes green and then yellow. BALLOON BLAST - Mr. Wizard explains carefully that this next experiment should only be performed with responsible Science Teachers. He is adding a flammable gas to a balloon. When finished, Shan tapes it to one side of a pulley arrangement while Mr. Wizard lights a blowtorch. Shan is to note the characteristics of the explosion as she pulls on the rope that moves the gas filled balloon over to the flame. The balloon explodes with a large yellow flame, next they perform the same experiment but with more oxygen and they note the difference oxygen makes in size and sound.

ABSOLUTE ZERO: Erin reads the temperature in the room from a wall thermometer: 23° Celsius. Mr. Wizard says she is going to use that temperature to find the lowest possible temperature in the universe. They use apparatus with a metal ball at one end and a pressure gauge at the other to find the lowest temperature. See how they do this. CAMPFIRE CHEMISTRY: With a torch Mr. Wizard is heating a flask with a side tube. The wood in the flask is turning black, the flask is filling with smoke, but there is no flame. What doe the wood need to turn into and what does it need to be combined with before it can burn?? MILK COLORS: In a tray Mr. Wizard and Dan watch swirling colors on a layer of milk. In another tray Dan pours milk. They drops of food coloring on the four sides of the tray. When liquid soap is run down the sides of the tray near the food coloring. The breaking of the surface tension by the soap swirls the color together to make a moving version of modern art. TOWER OF SALT: Mr. Wizard wants Shan to pour liquid in a flask into a small beaker. She doesn't think all the liquid will fit into the beaker. He explains that it may be because of a strange form of saturation. He shows her a saturated salt solution with the un-dissolved salt at the bottom of the container may be the reason. He explains crystallization. COPPERPLATING - Mr. Wizard shows Clara a key and a clamp which he has plated with copper. Clara has never plated anything but today she is going to copper plate an eye bolt. ELECTROCUTED PICKLE - The current is turned off the forks that are inserted into a pickle. Damon turns on the current and the pickle begins to smoke and flashes of light can be seen inside of it. The light is coming from the agitated sodium ions in the brine. A scientist in the 1800's ran electricity through water salt water and vinegar, so the reaction is known by his name: the Kolb Reaction.

They proceed to perform an experiment to see if in fact there really are iron particles in cereal. BALLOON IN BOTTLE TRICK - Mr. Wizard gives Chris a bottle & balloon, identical to his and tells him to repeat his action. They insert balloons in the mouths of the bottles and blow into them. Mr. Wizard's balloon inflates, but Chris's doesn't. Mr. Wizard then shares his trick with Chris! NUT LIGHT - Jeffrey is challenged to make an emergency light out of Brazil nuts. He is puzzled on what to do. Mr. Wizard shows him a nut supported vertically by three pins. When started with a match, it burns readily. STALACTITES - In a photo inside a cave a man shows an estimate of the size of stalactites and stalagmites. Mr.Wizard shows Vanessa homemade examples made by dissolv­ing Epson salts in two glasses of water and placing a piece of string between them. She sees the string act as a wick drawing the solution out of the glasses. The salt attaches to the string like stalactites. LIGHT IN MICROWAVE - A circular fluorescent bulb has no wires attached to it. Mr. Wizard directs Eliana to put it into the microwave oven. She is hesitant but does it and turns on the oven. The fluorescent bulb glows! When she asks why it glows, Mr. Wizard points out that there are two possible explanations. The bulb has mercury vapor inside which is agitated by the microwaves and hits the inside of the bulb which is coated with material that glows. Or the microwaves agitate the coating directly and make it glow. Mr. Wizard explains the instructions suggest having at least 50 cc of water to prevent the oven from overheating. When she turns on the oven, the broken pieces do not glow. Mr. Wizard explains very carefully that this experiment must be performed with a responsible adult at all times!! PAPER TUBE KAZOO - With simple materials, Kellie can make a musical instrument! Using the inside of a roll of paper toweling, a pencil, a sheet of wax paper, and a rubber band she follows Mr. Wizard's instructions: make a hole in the center of the tube with the pencil; place the wax paper over the end of the tube holding it in place with the rubber band. She is now instructed to hum into the other end. She hums Happy Birthday. She wants to know where the fuzzy sound comes from. Mr. Wizard explain her humming into one end vibrates the air inside the tube which in turn vibrates the tissue paper to create the sound of a kazoo. STEAM BURNS PAPER - A spout of steam and water vapor is coming from a copper tube connected to a tea kettle. Erin knows that the steam is 100° C. She holds a sheet of paper in the steam and then a kitchen match. The steam is not hot enough to effect either one. Mr. Wizard now heats the coil in the middle of the tube with a torch to produce superheated steam which is hot enough to char a hole in the paper and to light the match. This experiment must be performed with a responsible adult at all times!
