Science Supplies Needed

For our upcoming unit is Science we will be studying force and motion as well as simple machines. I would like to plan an inventions activity for the students but will need a few specific items.  If anyone has (or has the ability to make) any of the items below and would let us borrow/have them it would be much appreciated!

Thanks!!
