(#16) Pressure
Teaching about pressure is usually a matter of locating the right rubber stopper, with the correct number of holes, to fit a flask of the proper diameter, to accommodate glass tubing cut to the desired length. No wonder experiments on pressure usually end up as teacher demonstrations! This unit eliminates all the hassle and hazard with canning jars, rings and lids: 1/4 inch diameter rubber tubes fit perfectly through 1/4 inch lid holes backed by 1/4 inch washers. Your students will construct all manner of airtight and watertight systems that measure pressure, expand balloons, pump, siphon and more, simply by interconnecting and reconnecting tubes and jars.
(#16) PRESSURE is part of our Self-Directing Task Card Series. It is an 80 page soft-bound book organized into three main parts:
