In this notes on the screw instructional activity, 5th graders read 3 paragraphs about the screw, its history and uses, then write the main points of each paragraph in the right hand column.

This open-ended boat building exercise is meant to be part of a three-lesson series on ships. Links to the other two lessons are included. This particular part is mostly a group lab activity in which they build a boat, find its load line...

Pique interest in water pressure, demonstrate buoyancy, and explore water displacement concepts with a homemade Cartesian diver. You may want to change the name of the toy, however, as is is not documented the Rene Descartes...

Students examine why some objects float or sink. In this physics activity, students engage in several mini-experiments which challenge them to draw their own conclusions regarding why certain objects sink or float. An example of one...

Students illustrate Archimedes' Principle of Buoyant Force. In this graphing lesson, students will observe that the buoyant force on an object is equal to the weight of the fluid it displaces. Students will then create a graph showing...

Students explore the concept of density. In this density lesson plan, students determine the density of various objects. Students use the density of the various objects to predict the density of various unknown solutions.

Amaze your friends and family by moving water with just a few turns of your wrist, this is known as an Archimedes screw. In this science project, you will build a very simple Archimedes screw, to transfer water from a low-lying location...

This site, maintained by Dr. Chris Rorres of Drexel University, demonstrates how the design of Archimedes screw has made lasting impressions upon modern society. These historic engravings demonstrate the practical uses of the screw in...

Explains what a screw is, its history, the formula for calculating its mechanical advantage, the many types of screws in use, and some applications of screws today.

A short piece on Leonardo da Vinci from the Science Learning Network. Placed here because a) there's a decent drawing of an Archimedes' screw, and b) there's a link to an adequate definition thereof.
