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 to answer the following question:
Which paper column is the strongest?
To find the answer to this question you will need to make 3 different columns 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 before the column 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? (Hint – you will need a table with two columns. How many rows will you need?) What headings/titles will each of the columns of your table have?
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? See if you can find some images of buildings with columns. Can you see that architects and engineers use what you have found out when designing buildings?

We would love to see what you found out. Save photos in your 'My Work' folders on Purple Mash.
