| Objective |
To determine the density of an object in
the shortest time possible while traveling through an obstacle course. |
| Purpose |
To investigate the concept of density. |
| Participants: |
Teams of three or four. |
| Materials |
- Each team travels through an obstacle course with three relay
points where a team member is to measure one of the physical quantities
required.
- All required measuring devices are available at each relay
point.
- An example is to measure the density of a ping-pong ball.
|
| Rules |
- 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.
|
| Judging |
Points are awarded on the basis of time
taken and the accuracy of the final density value. |
