Simple Machines

1
Simple Machines

• Students will be able to reinforce concepts about
  simple machines, learned in the classroom. They
  will be able to understand simple machines using
  webquest and interactive web sites.

2
How do Simple Machines Make Our Lives Easier?

• (Let students write in their journal for 5
  minutes and then discuss.)

3
Instructional slide

• Over the past 2 weeks, we have learned about the
  six types of simple machines.
• Now, take this time to list some differences and
  similarities between these simple machines.

Instructional slide

• http//www.sciencetech.technomuses.ca/english/scho
  olzone/Info_Simple_Machines.cfm
• You can use this site for information. In groups
  of 4, start listing the similarities and
  differences between the six simple machines.
• Write your answers on a flipchart paper.

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.

6
Share

• Students can present their findings from the
  website.

Group A
Group B
7
Share

• Blank slide for documenting students ideas.

Homework

• Compound machines are a combination of simple
  machines.
• Go to http//www.edheads.org/activities/simple-mac
  hines/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?

Standards

• 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.
