2nd Grade Simple Machines

Miss Dewald’s second grade class recently learned about the six simple machines that help us work easier, faster, or better. They are the inclined plane, wedge, wheel and axel (including gears), leaver, pulley, and screw. After learning about all six simple machines, the students were challenged to invent a complex machine composed of at least two simple machines at home. They also wrote a report describing what simple machines their invention was composed of and how it made work easier, faster or better. During their complex machine presentation, the students demonstrated and presented their complex machines to their parents and other classes who came to see the inventions.
