Mathews, Tribune News Service photo by ceili cornelius Steven Peterzen worked with students on their project to launch a weather balloon over Sisters Country. Sisters students launch weather balloon By Jim Cornelius News Editor to “recognize the nature of sci- ence and design,” as Givot put it. Sometimes things fail and you have to go back and tweak the design — sometimes more than once. The overall mission was a success. Students were able to use GPS to locate the balloon’s landing site off Century Drive in the Mt. Bachelor area, and they hiked out to retrieve it. Givot hopes to repeat the project next year, citing the educational benefits not only of the fundamental scientific processes involved, but also the hands-on team-building that went into the project. “I will do it again in a sec- ond if it works out,” she said. The science process classes at Sisters High School capped their spring trimester studies with the launch of a weather balloon on Friday, June 5. The students assembled a payload of experiments designed by multiple sepa- rate teams, advised by sci- ence teacher Rima Givot, stu- dent teacher Heidi Gillespie and balloon expert Steven Peterzen. As president of ISTAR Group, Peterzen has international experience in sending up balloons, some- times with massive payloads. (See www.theistargroup.com.) Accordign to Givot, student experiments included weather monitoring and trajec- tory tracking; a test of atmospheric pressure change on algae pho- tosynthesis; effects of intense high-altitude light on inks; a test of earthworm survival at altitude; and an investigation of cel- lular change in flower petals. Givot said that there was an immediately obvious result to the last experiment. “There definitely was a change in the cells,” she said. Not all the experi- ments panned out. The weather monitor- ing equipment either failed or was not set up correctly; it returned no data. And the bal- loon — a 600-gram latex unit with a burst altitude of 100,000 feet — did not fly as high as anticipated. It topped out somewhere around 85,000 feet before bursting, due to a heavier payload. That’s all part of photo by ceili cornelius the deal though, and a valuable part of the up, up and away! the Sisters weather educational experi- balloon soared to over 80,000 feet and ence, allowing students landed near Century drive outside Bend. — Last Week’s Puzzle Solved — This Week’s Crossword Sponsors 25% LACTIC ACID GREEN TEA PEEL VITAMIN C MASQUE June Special - Only $65 Essentials Skincare Evens out pigment, increases hydration, refi nes texture and uncovers brightness.
