We used fasteners to put them into pieces of wood blocks. I found it was easy to screw in the fastener into a hole that was already there and it was easy to unscrew the fasteners. I found it was hard to put the fasteners in without using a old hole. I saw that some of the screwdrivers tips were magnetic. I noticed that the screws were different sizes and different colors and different magnetic poles.

I noticed that they had different sizes and different widths and different lengths. I learned that the screws go in a hole that is already there and  removing them is pretty easy.
