Title:

Investigate the Strength of Straw.

Purpose / Aim:

To Investigate the Relationship between the Number of Straw Used and the Strength of Straw when Weigh is Constant.

Abstract:

The purpose of this experiment is to investigate the relationship between the number of straw used and the strength of straw when weigh is constant. First and foremost, experiment was started by using one straw. The initial reading from the pointer was taken before the masses were suspended. Then, the slotted mass carrier together with constant masses in detail, 1000g, was suspended at the straw. As the result, the pointer will give the new reading. That reading was taken as the final reading. Step 2-5 was repeated for vary number of straws.

Based to the theory, when we stretched it, we are trying to overcome the intermolecular bonds between the molecules. At the same time we are also trying to change the position of molecules that are held together by the intermolecular bonds. With vary number of straws; its strength also will increase.

What we realized after conducting this experiment is once the number of straw increases as the result the
