We will test our bridges before the Christmas break.  The groups of Grade 5 students have to design and construct a bridge that allows a wind-up car drive across and then we test how strong they are.

Everyone tries to build strong bridges.  Here’s are some pics of our fun from previous years.

 

Some were stronger than others!

The Grade 4’s will enjoy building with pulleys and gears.  We will be testing the effeciency of our designs using Newton scales while cooperatively working with a partner.
