Students in Ms. Czerwinski's
11th grade Physics classes recently worked on a fun and challenging
project to learn some of the most important concepts in energy
and motion. The project involved the design and construction of
a rollercoaster using foam pipe insulation, wood dowels, wood bases
and a marble for testing. The goal is to construct a rollercoaster
with a minimum of two loops or the combination of one loop and
one corkscrew. The
marble needs to travel as fast as possible down the coaster but
also to significantly slow down at the end.
The slow-down
is checked by holding a raw egg at the end of the coaster track
and allowing the marble to hit it without causing any cracks in
the egg. Measurement and calculation of potential and kinetic
energy is also part of the project. This requires the students
to use various measurement devices such as metersticks, stop watches,
digital balances, digital calipers, CBL’s with graphing calculators
and photogate timing devices. |
