Simple Machines Continued

Continuing with our study of simple machines, we experimented with levers.  Where is the fulcrum? Where is the load? And does the nearness of the load to the fulcrum affect the amount of force or effort needed? We know the answers to these questions in the grade 3 and 4 classroom!

Simple Machines

The Grades 3 and 4 are learning about simple machines. How is an inclined plane used to move a load up or down? Is a longer incline better or a shorter one? How does friction impact movement on the inclined plane? These are the questions the students are investigating.
