Simple Machines Third Grade

The third graders have been very busy since the Thanksgiving holiday learning about Simple Machines. They found out that a machine is "anything that helps us do work", and that work is "done when something moves after a force is applied". Testing of the six simple machines is happening right now in the lab. After experimenting with all the simple machines, the students will then take a look at "Leonardo's Mysterious Machinery", and see how this great 15th century inventor, scientist, and artist, envisoned machines we see today. To conclude the Simple Machines unit, the students will design, build, and test their own compound machine using several of the simple machines.
