WALT carry out a fair test
In our science lessons we have looked at different materials and their properties. Today we would like you to carry out a fair test using paper as the material. You will be answering...
Did you know that the same sized piece of paper can hold different amounts of weight based on how it is shaped?
To find the answer to this question you will need to make 3 different structures out of paper: one with a square cross-section, one with a triangular cross-section and one with a circular cross-section. You will then test them to see how strong they are by placing books on each one. How many books can it hold before it collapses?
Before you start your challenge have a think about these questions:
During your experiment, record your results using a table. Can you draw your own table? It might look something like this...
|Paper shape||Prediction of how many books||How many books?|
After your experiment, think about your results. Were your predictions correct? What do you think your results show? (That’s your conclusion!) Which was the strongest? Which was the weakest? Can you try to explain why?
