Background For Teachers:
Simple machines have few or no moving parts. These machines use energy to work. Combining two or more simple machines results in a compound machine.
This unit on forces and motion can be more focused using and enduring understanding and essential questions. They are as follows:
Enduring Understanding: Forces cause changes in the speed or direction of the motion of an object. The greater the force, the greater the change in speed or direction.
What is a force?
Intended Learning Outcomes:
Show several kitchen tools, such as melon baller, spatula, pancake turner, pizza cutter, potato peeler, can opener, wooden spoon, jar with lid, etc.
What do these objects have in common? How are they different? Today we are going to learn about simple machines and how they can make work easier.
Six Simple Machines:
There are six different simple machines. We are going to learn what they are and how they can make work easier.
Show pictures/examples of the six different kinds of simple machines. Pass out the Simple Machines and Work recording sheet for students to complete while learning about the six types of simple machines.
Show the simple machines and the activity for each. After the introduction, students will do the experiments and determine whether each uses a push or a pull and how they are all used to help make work easier.
