Mr Lange's Year 11 Engineering

Elastic-band powered boats designed, engineered, built and tested by Mr Lange's Preliminary HSC Year 11 Engineering class.

Boats were limited to a length of 250mm and each boat was given one test run and one recorded run along a 3-metre long test 'pond'. After the test runs, students were permitted to make workshop adjustments to their boats.

The success of each boat was determined by its ability to stay afloat and its travel distance and rate.
