build an apparatus that forces a ping-pong ball to remain off
the ground for at least 15 seconds, but no more than 60 seconds.
materials listed above should be the ONLY materials used in
the construction of your device. The challenge of this activity
is to create a force strong enough to propel the ping-pong ball
into the air and keep it there for more than 15 seconds, but
no longer than 60 seconds using only the materials listed above.
finished apparatus should be no larger than 1 metre wide by
1 metre high by 1 metre deep. You may apply force directly to
the apparatus using only your hands or feet to set the experiment
in motion. The ping-pong ball may NOT be touched by your hands
or feet at anytime while in the air or during landing.
the apparatus has been set in motion, record the total time
the ping-pong ball remains in the air from initial launch to
touch down. Remember, the ping-pong ball should be in the air
no less than 15 seconds, but no longer than 60 seconds.
is best to perform this activity in an area of ample space.
the experiment a couple of times. Determine if there is a way
to modify the apparatus' construction so that you can keep the
ping-pong ball in the air a longer period of time with each
attempt. The test is yours to take.
