Fluids Unit Test - Study Hints

*The unit test is on Thursday, April 12
*If you are absent due to illness or athletics it is your responsibility to arrange a make-up date with Mr. Mak as soon as possible
*Extra help is ALWAYS available - speak to Mr. Mak

 -What are fluids? Which two states of matter?
-Aerodynamics and real-world uses/examples
-Hydrodynamics and real-world uses/examples
-Laminar vs. turbulent flow of fluids
-Viscosity - thick vs. thin, high vs. low, how cohesion impacts viscosity, flow rate
-Explain the difference between mass and weight
-Know common units for mass, weight and volume
-Archimedes' Principle - How to find the volume of irregular objects using displacement
-What is density?
-Solve questions using the density formula (with proper units!)
-Describe the impact of temperature on density and viscosity using particle theory
-Buoyancy - positive, neutral and negative - describe the forces involved (gravity vs. buoyant force)
-What is ballast? Give real-world examples (i.e. -submarines)
-Explain what hydraulic systems are, how they  work and give real-world examples
-Explain what pneumatic systems are, how they  work and give real-world examples
-Understand that gases are compressible

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). Research Before Starting: Articles: https://www.wikihow.com/Make-a-Water-Filter http://all-about-water-filters.com/top-easiest-diy-water-filters-you-can-make-at-home/ http://pbskids.org/zoom/activiti...

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 ...
