||To determine the density of an object in
the shortest time possible while traveling through an obstacle course.
||To investigate the concept of density.
||Teams of three or four.
- Each team travels through an obstacle course with three relay
points where a team member is to measure one of the physical quantities
- All required measuring devices are available at each relay
- An example is to measure the density of a ping-pong ball.
- First member receives the ball from the judge, proceeds to
Relay point 1 and determines the mass of the ball.
- Member number two is told verbally the mass and proceeds to
Relay point 2 where the volume of the ball is measured.
- Member number 3 is then told verbally the mass and the volume
and travels to Relay point 3 where pencil and paper is available
to calculate the density.
- When the ball and density value is placed on the judges table,
the timer will stop.
||Points are awarded on the basis of time
taken and the accuracy of the final density value.
