Marble Run

The marble run was a big success!

The challenge was to try and build a marble run and make it go all the way down.

The first thing we had to do was draw a plan.  

Next we got the materials.  We had nails, cardboard and wood.

Then we screwed on the cardboard and then we put the marble down.

It did not work right away because we had to move one of the cardboard pieces so that the marble wouldn't fall.

If I were to do this again the thing that I would do differently is I would make it bigger.  I think we did a good job.
