COUJLCX DATA Amy Dunn and Kurt Hamilton collect a sample of gas in IPS. Safety goggles were required throughout the labs conducted in the science depart- ment. Angela Valdez and Jim Silva use water displacement to collect a bottle full of air. In IPS students worked in groups of two or three in the labs. Working skillfully and efficiently. Scott Cornett works to get the proper lab data. Working alone was a rare sight because the procedure was harder to follow with only one pair of hands. 12 - Science Labs

Jim Silva and Trent Lynn shape a project using the ban saw in the Metals room. Metals attracts more and more students every year because it is so interesting and allows for creativity. Bending scrolls is part of the pro- cess of making a bowl as Brad Hammack illustrates. Metals was a challenging and fun class. i Mike Leach cuts sheet metal for his metals project. Cutting sheet metal was not exactly fun. but it was necessary for many projects. Using an exacto kit, Becky Mall works on her woods project. Becky was outstanding in woods. Taking every precaution. Bill Reinhard planes a piece of wood for his project. Safety was often stressed by Ed Holcomb. Working in metals, Pat Reynolds uses the grinder. The grinder was used in many projects.

John Couey tries to release air bubbles from a test tube. To acquire pure hydro- gen, all air has to be removed. A great way to see how chemi- cals react or how a star fish's char- acteristics are important to its sur- vival is by participating in a lab. IPS and Biology are examples of classes that can get you started in higher chemistry or in human anatomy. IPS and Biology are great calsses to prepare our stu- dents for their future academic ca- reers'' commented Larry Wagner, the Mazama IPS teacher. Students always seem to enjoy lab days. Spirits were raised when they were doing labs maybe because there was no written work or maybe be- cause the students could get their hands dirty. Most labs required calculations and mathematical formulas to determine the weight or density of a chemical. Lab days in Biology included the dissection of worms, frogs, and crayfish. The dissection of certain creatures went along with the chapters in the textbook that the students were learning. The students would get a better idea in the characteris- tics of a mammal by doing a dis- section. gas during an experiment. IPS students Mara Bailey heats up a mixture to release conducted many experiments throughout hydrogen gas. The students collected sev- the school year, eral bottles of hydrogen to test for differ- ent reactions. Science Labs - 13
