The student will investigate and understand simple machines and their uses. Key concepts include:
a) types of simple machines (lever, screw, pulley, wheel and axle, inclined plane, and wedge);
b) how simple machines function;
c) compound machines (scissors, wheelbarrow, and bicycle); and
d) examples of simple and compound machines found in the school, home, and work

Teacher Name: 3rd Grade Science CCTS
Grade Level: 3rd
SOL: 3.1 and 3.2
Suggested Research Materials:
After investigating simple machines, using the above research resources, students complete a scavenger hunt through the school to identify simple machines in the real world. Students will take pictures of their findings using digital cameras and/or ipads. These pictures will then be analyzed in class to see how these machines are utilized in real world situations.
Suggested Design Brief:
Engineering Design Brief from MSIC Students will design and build a compound machine that will complete a task presented on the Task Card provided.
Suggested Reflection Activity:
Students will test their compound machine in class to determine its ability to complete the task assigned. These tests will be video taped in class. They will evaluate the effectiveness of their machine and discuss what changes could be made in order to make a more efficient design. These comments will be paired with the video taken in class to create a multimedia presentation.
