object of this project is to construct a bridge designed to
transport an unbroken egg over an open span of one metre using
only the force of gravity.
box of #1 size paperclips
1 box of narrow 8 inch straws
pair of scissors
two raw eggs
Using the paperclips and straws, design a bridge that covers
a distance of one metre.
2. Only the supplied materials may be used.
3. The egg may be given an initial nudge to set it in motion,
but after that only the force of gravity can be used to help
carry the egg along the bridge.
4. Do not touch the egg once it has started to roll along the
bridge. If the egg looks like it is going to fall off the sides
of the bridge you can catch it so it doesn't land on the floor.
5. Modify your bridge and try again until you can get the egg
to cross the bridge without falling off or breaking.
When the weather is nice this is a great activity to do out
in the backyard. Lawn chairs and picnic tables make great platforms
to support the ends of your bridge. Experiment with different
designs to determine which one supports the egg the best and
allows it to move easily across without fear of falling.
