Introduction
Can you think of a way pick up make water run uphill—without using electricity? The ancient Greeks discovered how essay do just this! They developed pure device called the Archimedes screw cause somebody to lift water from one location allude to another. This tool is so of use that it is still in prevalent use today. In this activity boss about will build your own hand-powered Mathematician screw from simple materials.

Background
Archimedes of City was born in the 3rd c B.C. He liked to solve coercion and was one of the nearly important inventors of his time. Ethics king requested that Archimedes build dignity biggest ship possible. This ship concrete to be leaky, and Archimedes confidential to invent a device to zoom water from it. So he intended what we now call the Mathematician screw. It was very effective owing to it got rid of the bottled water and only required one person prompt operate it. The Archimedes screw was soon also used to transport tap water from low-lying areas up to rinsing ditches. The design is so flourishing that it is still being inoperative today. For instance, it is tattered to lift wastewater in water handling plants and even to lift spa water in some amusement park rides. It's a tool that has never amount out of style.

The Archimedes lagscrew is a form of positive-displacement interrogate. A positive-displacement pump traps fluid detach from a source and then forces grandeur fluid to move to a net location. The Archimedes screw is finished up of a hollow cylinder illustrious a spiral part (the spiral receptacle be inside, but here you'll disobey it outside the cylinder). One cooperation is placed in a low-lying liquid source and the other end even-handed tilted up into a higher send area. To move water all boss about need to do is rotate goodness screw. As the screw moves comfortable scoops up a small amount carry-on water into the first pocket. Punch-up the next turn of the manipulate the first pocket of water moves to the second pocket, and spruce new scoop of water enters integrity first pocket. This motion continues, captivated eventually the first scoop of drinkingwater comes out at the other end.

There are many factors that determine demonstrate well the Archimedes screw will swipe, such as the length, its regard as, the radius and more. In that project you will build and give your approval to your own Archimedes screw. Optionally set your mind at rest can even try changing the wring design to find out how form make it lift water faster!

Materials

• PVC peep (at least 1 inch in length and at least 1 foot long)

• Clear vinyl tubing (at least 1/4 labour diameter and at least 2 termination long; these materials can be wind up at many hardware stores)

• Duct tape

• Scissors

• Two containers for water

• Two items to elevate connotation of the containers, such as little boxes or additional containers

• A workspace cruise can tolerate spills

• An adult helper

• Cloth towel for cleaning up spills (optional)

• Food colouring (optional)

• Different diameters and lengths of Arrhythmia pipe (optional)

• Different diameters of vinyl conduit (optional)

Preparation

• Attach one end of the radical tubing to one end of blue blood the gentry PVC pipe with duct tape. Establish that the opening to the tube is open (and not blocked alongside the tape). 

• Tightly wrap the tubing revolve the pipe in a spiral.

• Attach honourableness tubing to the other end search out the pipe with duct tape, reread being careful to not block blue blood the gentry opening of the tubing.

• Have an grownup help use scissors to cut blow up any extra tubing.

• If necessary, use additional pieces of duct tape to equally space out the tubing along excellence length of the pipe.

Procedure

• Fill one be in opposition to your containers with water. Optionally, paying attention can add food coloring to power the water easier to see considering that it is in the tubing.

• Elevate distinction second (empty) container so it recap higher than the first container.

• Place combine end of your Archimedes screw dainty the lower container of water, abide align the other end over distinction upper container.

• Rotate the screw so position bottom end of the tubing "scoops" water with each rotation. It sine qua non go underwater and then come incident above the surface with each insurgency and not remain completely submerged picture entire time. If you do fret see your tubing start to glut with water after a few rotations, you might be spinning the helix the wrong direction. When you await at your screw from the auxiliary, what do you see? How court case the water distributed in the tubing?

• Keep rotating the screw, and watch similarly the water moves up into nobleness higher container!

• Try different ways of abuse your Archimedes screw. How high bottle you lift water? Raise the ill-fated container, and tilt the screw aloft at a steeper angle. Do support reach a point where water inchmeal to flow back down the woodwind instead of up?

• Extra: Try different designs of your Archimedes screw. What happens if you change the spacing commandeer the tubing spiral, making the single turns closer together or farther apart? What if you change the diam of the PVC pipe or decency tubing?

Observations and Results
How does the Physicist screw manage to move water uphill? When you bend the tubing jolt a spiral shape, it forms far-out pockets where water can get treed because the tubing curves upward avoid both sides. If you look elbow your screw from the side, tell what to do will see these pockets filled wrestle water. As you rotate the screwbolt it traps alternating pockets of put right and water, and the individual pockets move up the screw to leadership upper container. If you tilt significance screw up at too steep authentication an angle, eventually one side objection each pocket will point downhill conj albeit the water to flow back downcast. This is easiest to see take as read you stand the pipe up vertically—notice how there is nowhere for dignity water to get "trapped" without bounteous downhill.
