Raindrops (MathDL: JOMA)
raindropsThis is a module for beginning calculus students to study differential equations that model falling objects subject to air resistance -- for example, raindrops -- and to develop Euler's Method, a tool for approximating solutions of initial value problems.. read full text...

A Craftsman Divides a Rectangle (Demos with Positive Impact)
To demonstrate how a craftsman such as a carpenter, cabinet maker, or sheet metal worker can divide a rectangular piece of material into a number of regions of equal size using a pencil and straight edge. The technique illustrated in this demo avoids cumbersome and sometimes inconvenient direct measurements. (This demo uses elementary geometry). read full text...
