Snack: Cut a long rib of celery and
roll green or purple seedless grapes down it. But don't let the grapes fall on
the floor - eat them! And when you're done, eat the celery, too! Wash it down
with some chocolate milk.
Toilet paper cardboard tubes
Duct tape, preferably one roll per
Marbles or other small balls - same
size for each team
Best to do this in a carpeted room
that the marbles can roll on,
but not too quickly
Measuring tape | Posterboard and
marker or chalkboard and chalk
is fun to do in teams. Your assignment is to collect and then divide up as many
toilet paper tubes as you can - another good reason to recycle them! - so that
each team has the same quantity.
Try to get enough for each
team to have 30 or more. If you ask around your neighborhood, church and
school, people will help you collect them!
Each team is also given
some duct tape to connect the tubes. It's easy to tear off, so you don't need
scissors. But wait to hear what you're going to do before you start building.
here's the challenge: build a structure with your toilet paper tubes that will
roll a marble the farthest. You will be compared with the other teams, so make
sure to plan out a great design . . . so that you can win the Toilet Bowl!
this on a carpeted surface so that the marbles don't roll TOO far. You can try
small rubber balls or other balls that will fit inside the tubes, but marbles
seem to be the easiest to use.
you'd like, use a measuring tape to chart the distances and announce the winner
really fun to allow each team some time between rounds to alter their design to
try to get their marble to roll farther.
good teamwork, and think hard about how best to use your materials to design
and build the best possible marble-roller.
luck, and have fun!
