Year 7 technology

dragsters

By the end of the unit the students needed to create a race car made out of Balsa wood, drill holes to include wheels and sand, decorate and paint it in time for race day. In class they were asked to think of ways to ensure that their car would be faster then anyone else's and had to research different design features.

The design features would play a large role considering all students were given the same piece of timber. The cars were attached to the track using a fishing line, students had a trigger that they needed to push to release the car from the starting line, cars then made it down to the end of the track in under 2 seconds using the CO2 cartridge in the back of the car.

It was great seeing the enthusiasm of the students, and their support for one another on race day. We had a few senior students offer to assist and without their help the day wouldn't have been such a big success.
