The Teacher’s Guide employs several different fluid pressure
demonstrations, activities, graphic illustrations, transparency
templates (for overhead and/or digital camera projection),
evaluations, reference materials, chart-graph worksheets, and
extension activities. Extension activities include scientific
method, control variables, independent variables, dependent
variables, and developing hypothesizes.
Lessons address pressure concepts in science: Why does a balloon
expand as it rises? What helps a fish hover effortlessly at a
particular depth? How does a pump work? How does a barometer predict
weather? How can a hose siphon water? Why is household faucet water
under such great pressure? Why are ships are more buoyant in the
ocean than in fresh water? How are ballast tank pressure principles
related to submarines, scuba divers, and fish? How is air pressure
related to the function of our lungs and ear drum? How does a jack
or dozer blade use hydraulic fluid pressure to function?
Kit includes: Submarine, ballast tank, air line with
connectors, “T” cap, grommets, air pump syringe (2), and
