We have had to learn about some key scientific ideas relating to gravity, friction and momentum. All groups know that we need to reduce as much friction as possible, as too much will slow the carriage down. Now that we have built a makeshift testing ramp, groups have been testing and modifying their carriages, playing around with weights, different wheels, spoilers and axle placements, to name a few.
There is a lot of buzz around this project, evident through the number of students who found many of their materials at home (mostly in their yellow recycling bins). We are really looking forward to the competition.
