E07 Forces in Fluids, Work, Power and Machines
1. The Student Will describe and calculate pressure and relate water depth and altitude to changes in pressure. (p. 390 – 393)
2. TSW describe how forces from pressure are distributed at a given level in fluid. (p. 391 – 392)
3. TSW describe how pressure is transmitted in a fluid according to Pascal’s principle and use it explain how a hydraulic system works to change a force. (p. 394 – 397)
4. TSW explain the effect of buoyancy on the apparent weight of an object and the relationship between the volume of a fluid displaced by an object and buoyant force acting on the object according to Archimedes’ principle. (p. 400 – 404)
5. TSW describe the relationship between object density and fluid density, and object weight and buoyant force and use these to determine whether an object sinks or floats in a fluid. (p. 400 – 404)
6. TSW describe the conditions that must exist for a force to do work on an object and power, and calculate work and power. (p. 412 – 415)
7. TSW describe what a machine is and relate the work input to the work output of a machine and how this makes work easier to do. (p. 417 – 420)
8. TSW compare a machine’s actual mechanical advantage to its ideal mechanical advantage, calculate advantage and efficiency, and use this information to explain why the efficiency of a machine is always less than 100%. (p. 421 – 426)
9. TSW name, describe and give an example of each of the six types of simple machines and describe how to determine ideal mechanical advantage of each type. (p. 427 – 434)
10. TSW apply the scientific method in a variety of ways with a focus on one or two areas of the process. (Appendix in Curriculum Guide)
