I gf ,,,.y er:n!E'i'?5- ld le Q l f,I Qi Surve or's Transit Assists Students In Trigonometry Problems I etermine the height of the new pit from the peak of the skylight to the floor YOU MAY NOT LEAVE THE MATH CORRIDOR TO SOLVE THIS PROBLEM. So reads the most difficult of the 3 problems that trigonometry teachers, Mr. George Zerfass and Mr. O.L. Mutch- more, assigned their students. The problems are practical applica- tions of the triangle properties we study in Pre-calculus 173. said Zerfass. The problems become physical to the stu- dents and therefore are easier to under- stand than a written story problem. The problems were originated by Zer- fass when he began teaching the pre- calculas course in 1971. When I found out the school had a surveyor's transit, I decided to teach the students how to use it. remarked Zerfass. The transit is used by groups of 2 or 3 on students' own time. Still, students must submit their own write-up of the problems accompanied with diagrams. The other problems include finding the length of the math corridor and the distance form the top of the bus lobby's. antenna to the math pit's landing. Seventy-five percent of the pre-calcu- las students do the problem although Zerfass feels that the number might be less if the solution didn't net his pupils 30 points extra credit.

Movie Introduces Pupil - - n April, Glenbrook South viewers got a surprise if they ' ' happened to turn to channel two to watch a made-for-TV movie, Flesh and Blood . Junior Liz Ventura had the opportunity to stroll in front of the camera as an extra in a certain episode. Some days ended up with a total of 12 work hours, patiently taking and retaking various shots for the movie. Being an extra means a lot of stand- ing, sitting and waiting, explained Liz. Also being very active in the school productions, Liz has been sound tech- nician for The Wonderful Ice Cream Suit, assistant stage manager for Matchmaker, and student director for 1968. I love participating in shows whether I'm acting or not! explained Liz. In a cast with nine other Old Or- chard Country Club actors, she did I Never Saw Another Butterfly. Liz no- ticed several differences in working on theatre outside of school. The the- atre at Old Orchard is about one fourth the size of the one here, so I found myself talking so loud I was blowing away the whole first row with my voice! Liz Ventura doesn't know if she wants to pursue an acting career, but she feels that her the- atre experience will benefit any career she chooses. ,...a...,..s,.,r-ywaaisa I r . s- ,r .V .
