Simple+Machines

Lesson Plan on Simple Machines (Review)

Title: Simple Machines

Description: Students will use interactive websites on Simple Machines to reinforce concepts already learned in the classroom.

Duration: 90 minute (block of two periods)

Learning Objectives: Students will be able to reinforce concepts about simple machines, learned in the classroom. They will be able to understand simple machines using an interactive web sites.

Materials: Computers, Internet Access, Flipchart Paper

Step by Step Procedure:

1) It’s time for a review. Students will write in their journals for 5 minutes on “How do simple machines make our lives easier?” Brief classroom discussion.

2) Students will use an interactive website to help them review what they have been learning for the past two weeks.

http://www.sciencetech.technomuses.ca/english/schoolzone/Info_Simple_Machines.cfm Using the above website, students will first review the differences and similarities between the simple machines. They will work in groups of 4 and write their findings on flipchart paper. Students will share their findings in a classroom discussion.

3)Student Activity: http://www.edheads.org/activities/simple-machines/index.htm

Now, all students will go to The House. Group A will go to the Garage and Bathroom, found on the following site. Students in Group B will go to Bedroom and Kitchen, found on the above site.

TASK: Complete the activity on the website. Write down at least 3 specific places where you find simple machines.

Students can present their findings from the website.


 * Group A ||  ||
 * Group B ||  ||

Students can share their findings in a classroom discussion.

4) Homework: • Compound machines are a combination of simple machines. • Go to http://www.edheads.org/activities/simple-machines/index.htm • Enter the Tool Shed and write down at least 5 compound machines. Beside each compound machine, list all of the simple machines found • Write down at least 2 compound machines used in the classroom?

• Key Idea MST4.PS5: • Energy and matter interact through forces that result in changes in motion. • Key Idea Introduction: • Examples of objects in motion can be seen all around us. These motions result from an interaction of energy and matter. This interaction creates forces (pushes and pulls) that produce predictable patterns of change. Common forces would include gravity, magnetism, and electricity. Friction is a force that should always be considered in a discussion of motion.

• When the forces acting on an object are unbalanced, changes in that object's motion occur. The changes could include a change in speed or a change in direction. When the forces are balanced, the motion of that object will remain unchanged. Understanding the laws that govern motion allows us to predict these changes in motion. • • Performance Indicator MST4.I.PS5A: • Students describe different patterns of motion of objects.

• Major Understandings 5.2g Simple machines include a lever, a pulley, a wheel and axle, and an inclined plane. A complex machine uses a combination of interacting simple machines, e.g., a bicycle.
