Hi
I'm not a physicist but I'm looking for a simple way to test the hardness of different materials. I need to do a demonstration and collect results with a science class, the task sheet that accompanies the lesson says to place a cloth over the materials and hit them with a hammer. I would prefer a simple experiment that would allow me to calculate the force I apply to each material and then calculate the hardness based on the indentation left by the mass. I am aware of experiments involving small round objects and measuring very small indentations with a special microscope. Is there any way I can do a similar test on a larger scale? The results don't have to be very accurate, just as long as we can see a difference between the materials. Your ideas would be appreciated.
Thanks
Darren
