Module 4: Fluids & ThermodynamicsInstructors GuideLesson 1: Bell Jar ExperimentsHave students work in groups of 2. Provide each group with the following:Bell Jar SetSilicone based lubricant (to lubricate the orings)Large and small marshmallowsCan of shaving creamHot liquid (water or coffee)Small balloonThe micro bell jar enables you to create a vacuum to learn about air pressure and its effectson temperature and the volume of objects. The syringe and one-way check valve systemconstitute the vacuum pump.PartsA – Bell Jar with top connectorB – Bottom PlateC – “O” ringD – Hose with one-way valveE – Hose with T and check valveF – SyringeG – Plastic cupH – Suction cupBasic Setup & Operation1. Assemble the Vacuum pump asshown in Figure 1.The fitting from the side-arm of theT connects to the syringe with lightfinger pressure and a partial turn.The other fitting connects to part Dwith a partial turn.2. Attach part E to the connector on thetop of the bell jar. (Figure 2)A turn of approximately one-third isall that is needed to make theconnection secure.Do not over-tighten!
