Year 4 - Simple Machine Prototypes

This week in Year Four, the children had the opportunity to create a prototype of a compound machine, incorporating two simple machines: a pulley and an inclined plane. They experimented with various materials and techniques to determine how best to construct a freestanding inclined plane.

Through observation and discussion, Year Four came to the conclusion that thin cardboard was not a suitable material for this purpose. As a result, in our next lesson—when we will be constructing another simple machine—we plan to use thicker cardboard to improve the stability and effectiveness of the design.
