This week the heroes have been working on their marble run. The task was for the marble to go from the top of the poster board to the bottom and be able to knock dominoes down.
On Monday the heroes drew their ideas, and their design.
The rest of the week the heroes built their marble runs and tested the dominoes. They checked their design and made changes or added parts.
Thursday and Friday the heroes also started adding information about the different parts of machines; inclined plane, pulley, lever and fulcrum, wheel and axle and gears.
The heroes are so excited to share their marble runs for exhibition.
