This apparatus allows for a number of impressive demonstrations regarding vacuum and air pressure. Clearly shows the method by which a pump works. Demonstrates that air has mass and how to find the mass and density of an air sample. Shows that a sealed balloon will expand when the surrounding air is removed and how a suction cup is held on by external pressure, rather than suction. Demonstrates liquids boil at reduced temperature when under reduced pressure. Reproducible pages in instruction manual guide students through the experiments. Also includes follow-up questions, as well as teacher notes and answers. One-year warranty.
