Experiments uphold ramid s powers Pyramids fruit flies and rats stowed in Mr Thomas Jack son s biology room evinced the long range experiments which drew students interested in either biology chemistry or phys ics into groups involved in a single analysis Teams of two to four were created to initiate and organize each proiect under the supervision of the club sponsor Mr Jackson and his assistant Dr Otis Smith One group proposed to test the alleged powers of the pyramid by building 10 or 15 cardboard structures of different dimensions Members noticed after several weeks that a raw squid placed under one pyramid never rotted but dried like jerky and a razor blade became sharper ln an animal behavior study the intelligences of a rat and a mouse were tested by timing each one s progress through a maze to the food awaiting them at the end In a comparison of the timings the mouse was declared the most intelligent Reactmg to the theory that the long submissions of scuba div ers to underwater pressure results in a decrease of male off spring seniors George Creighton and Tony Eades began prep arations for a simulation observation to the completed in the summer In determining any change in genetical structure due to pressure three pairs of adult fruit flies are placed inside a metal chamber equipped with an air pressure valve and gauge and an air compressor inflates the chamber till it reaches the pressure equal to that exerted by 33 feet of water After a week the adult flies are removed and the larvae are left The cycle is repeated and the consecutive number of male offspring is compared to that of a group of flies bred in a normal environ- ment. In addition to the long-range rojects short experiments with infrared photography the re raction of light and laser paths were conducted. March brought competition. Senior Jon Nettles received an honorable mention at the Science Fair held in the Astrohall with his engineering project. He designed a plan of temporary class- rooms at the south campus to house the north campus stu- dents in case of an emergency. Competing by tests seniors David Severin Alan Mosley Nettles and Sheree Kemp traveled to Texas A8tM Universit for the Junior En ineering Technolog- ical Society Annual Con erence while Nett es Kemp and senior Steve King attended the UIL Science Competition at LaPorte High School. A. Before beginning an experiment dealing with light and lenses sen- ior Dennis McHenry Mr. Thomas Jackson Sheree Kemp and Jon Net- tles view slides depicting the refraction of beams. B. After etherizing the adult fruit flies senior George Creighton waits for all of the insects to fall asleep so he can separate the males from the females by observing them under the microscope. an experiment dealing with light and lenses senior Dennis McHenry Mr. Thomas Jackson Sheree Kemp and Jon Nettles view C. In a test comparing the intelli- gence of a rat to that of a mouse Tony Eades releases the rat into a maze in order to time its progress in finding the food at the end. D. Unable to perform the previously scheduled laser experiment due to malfunctions in the equipment, seniors Kyle Zollers and Tony Eades try to determine the focal lengths of several lenses and mirrors. E. Using a pulse machine belonging to the Science Department, senior Clara Ferguson checks the frequency of her heartbeats in comparison to those of members Tony Eades, Jon Nettles and Sheree Kemp. F. Having the directions explained by Dr. Smith, Dennis McHenry pre- pares to find the wave length of light. G. Testing the powers of pyra- mids, Dennis McHenry hands Sheree Kemp a raw squid to place in the frame. Left in the pyramid for several months, the squid never rotted but merely dried like jerky.
