1 Putting It In Motion

2 Complete Student Log Book: Pages 2 and 3

3 What is Motion? What do you want to know about motion? List 5 things that can move or be moved that can be found around your house.


5 Linear Motion A movement in a straight line between two points Examples?

6 Rotational Movement A movement along a curved path or in a circle Examples?

7 Reciprocating Motion Movement that goes up and down in a straight line Examples?

8 Oscillating Motion A movement that goes backwards and forwards in a straight line Examples?

9 Homework Activity Please bring in some toys for next day.

24 Wedge Inclined Plane Screw Wheel and Axle Lever Pulley

25 Simple machines are useful because they can make a physical job easier by changing the magnitude or the direction of the force exerted to do work.

26 Have you ever tried to unscrew a nut, bolt, or screw from something with your bare hands and discovered that it was just too tight to loosen even if you had a good grip?


28 You got the proper tool, such as a screw driver or wrench, and unscrewed it!

29 Why is it that it's so easy to unscrew with a tool when you can't with your bare hands?

30 The wrench and screw driver are examples of a wheel and axle, where the screw or bolt is the axle and the handle is the wheel. The tool makes the job easier by changing the amount of the force you exert. Axle Wheel

31 All of the simple machines can be used for thousands of jobs from lifting a 500-pound weight to making a boat go. The reason why these machines are so special is because they make difficult tasks much easier.

43 Homework Assignment Complete Student Logbook Pages 18 and 19

44 Levers There are three classes of levers:

45 Levers First Class : It has the fulcrum between the effort and the load. Fulcrum: the place where the lever turns

46 Levers Second Class: the load is located between the effort and the fulcrum.

47 Levers Third Class: The effort is between the load and the fulcrum.

48 Exploration: Investigate the Lever – Page 34 Complete Student Logbook Pages 20 and 21
