Rubber Band Code

Sat, Dec 6, 198625 mins

IRON CLAD MAGNET: Ashley uses an electromagnet Mr. Wizard has made to explain how he (Ashley) has made one at home. They connect a battery and Ashley picks up a pile of paper clips with the electromagnet. Why do all except a few paperclips fall off?? WHAT'S THIS? From this angle you can see only half of this familiar seed. Each half is called a cotyledon. Food is stored in them to be used by the new plant until it can begin to produce food on its own. CATENARY ARCH: Maria places blocks together on a board to form an arch on its side. They carefully put the keystone in place. She slowly raises the board until it is vertical. SCIENTIFIC NOISE: Mr. Wizard briefly explains to Nicola that an oscilloscope is a device to make waves visible. He produces a sound that appears as a pure wave on the oscilloscope screen. Nicola turns on the radio tuned between stations. They hear so called white noise because it is made up of many frequencies. On the scope it appears as many jagged lines and compare to that on a radio. They discuss signal to sound ratio. RUBBER BAND CODE: Bibi examines a rubber band with black marks on it that are a secret message. Mr. Wizard stretches it to expand the marks into letters. She reads a secret message on the rubber band. MONO LAKE: A big, blue lake in the dry desert of eastern California. A welcome sight to a thirsty traveler but a disappointment. The water is saltier than the ocean. Despite its high salt content, Mono Lake has supported abundant wildlife for thousands of years. Tens of thousands of California gulls nest here and more than 60 other birds species stop at the lake on their migrations back and forth between Canada and South America. The outcome is discussed. TORSION BALANCE: Mr. Wizard and Leila look at a metal strip suspended horizontally with two C-clamps attached to the end. When pushed, it goes back and forth like a vertical pendulum would. STEAM ENGINE RUNS WITH C02: Mr. Wizard shows Ashley the various parts of a steam engine
