  • Know the formula for mechanical advantage (MA)
  • Know how to solve MA problems
  • Know the units for MA
  • Understand and explain the difference between the size of the load force and effort force when the MA is greater than 1, exactly 1 and less than 1
  • Identify and understand the difference between class 1, class 2 and class 3 levers
  • Know two examples of class 1, class 2 and class 3 levers
  • Explain the purpose of using levers
  • Label the fulcrum, effort force, load force, effort arm and load arm on a lever diagram

Water Systems Hands-On Task - Creating Water Filters

Image
Design Task - Creating a Water Filter to Remove Impurities from a Non-Potable Freshwater Sample             In groups, you will research about, design, and then build, two simple water filtration devices, using only materials that can be found in the wilderness. One filter will have three filtration layers and the other one, five layers. You will filter a total of two 500mL samples per device. Your goal is to create the cleanest possible water sample. Successfully filtered water will be judged by having a reasonable odour (smell), have minimal discolouration (“brownish or yellowish-ness”) and look nearly transparent (see-though, with as few floating clumps or particles as possible).

Introduction to Mechanical Advantage and Efficiency

Image
Introduction to Mechanical Advantage and Levers List five things machines do. (p 8) A machine is a _______________ made of one or more _______________ that work together to accomplish a task. (p. 8) Describe the subsystems a can opener is made of and what the role of each subsystem is. (p. 8/figure 2) Explain what a mechanism is. (p. 8) In your own words, explain what a self-correcting control is. (p. 9) Explain what a lever is. (p. 10) Give four or five real-world examples of levers. (p. 10) Explain why are levers useful. (p. 10) Levers are broken down into three types. List them. (p. 10) Give one or two real-world examples for each type of lever. (p. 10/11/figure 1/2/3) All levers require a fulcrum, load force and effort force. Explain what each of these are. (p. 10) Make a quick sketch of a Class I, Class II and Class III level. Neatly label the fulcrum, effort force and load force on each diagram you made. Also label the load arm and ...
