triggering scientific thinking : high rise

willl it collapse?

The goal is to build a free-standing framework which will support weight one metre above the ground. The framework which can support the most weight is the winner.

proud with their works.....
materials:
straws, pins, tape, papaer clips, elastic bands, sciccors, metre ruler, set of object of varying weight.

waiting for he judgement....
Doing it.:
1. the framework is built using straws. Straws can be joined together in many different ways. You can make a long straw by squeezing one endof a straw and placing it in another. You can pins or tape to hold straws together. You can bind straws where they intersect with elastic bands.Straws can also be put together with paper clips.



final touch......

which structures can support the lowest weight object one metre above ground?


which structures can hold the most weight?


judgement time....


keep adding weight untill all but one structures copllapse..


is this the winner?....
