Inquiry | Screw

LI.to Screw and how it can move objects uphill.
This week we had being working on another tool which is a screw. To learn how a screw works was we did an experiment on carrying the water up hill through a little tube around a think stick, and we had to tape it so it won't fall, also we had to tuen the stick around and around so the water can come out of the other side.
