Activity idea
In this
activity, students design and build a balloon-powered car to better understand
the science ideas related to rocket propulsion. They use ideas of mass and
force to work out ways to improve the distance travelled by their car.
By the
end of this activity, students should be able to:
·
design and build a
balloon-powered car
·
describe how their car is
designed to go as far as possible
·
use ideas of mass and forces
(such as thrust, air resistance and wheel friction) to describe what might help
their car travel further
·
explain what causes the balloon
car to start moving, using ideas of action and reaction forces
·
explain that momentum keeps
their balloon car moving once the balloon is no longer applying a force and
that it will slow down because of the force of friction.
We trialed many times and failed, but with the attitude in Room 9 of 'don't give up!', we persevered and achieved some amazing results.
Our cars wreaked of creativity, which just goes to show 'old fashioned fun' and a lot of human air can still be had in the 21st century classroom.
Here are some pics of our cars along the way and a short movie for you to see how it all came together on 'RACE DAY'.
