We spent some time observing sawdust and wood shavings. We discovered that wood shavings are bigger than sawdust and that both of these materials are used to make particle board.
We also did a little more observing of the particle board and plywood samples because we will soon be making these manmade types of wood in our classroom!
particle board is very usefull in saving enviornment because it is made by using lot of wood wastage not as reliable as wood but lot of furniture is made using particle board
