Anne has been given samples of aluminium, copper and an alloy of the two metals. She has rods, wires and blocks of the 3 metals.
design a series of tests so that anne can find which of the 3 metals is:
I. the hardest
ii.is the most difficult to snap(has the greatest tensile strength)
iii. resists corrosion best.
say how you mad each one a fair test and how you would collect reliable data.
