Causal Reasoning
Does excessive exposure to violent video games cause violent behavior? Does increased gun availability cause more crime or less? Causal claims permeate everyday life and are constantly the subject of "studies" reported in the newspaper. The material in Causal and Statistical Reasoning examines the nature of causal claims and the statistical sorts of evidence used to support them. The material is contained in: approximately 20 content modules, a repository of over 100 short case studies, and a "C

Private Universe Project in Mathematics: Workshop 3. Inventing Notations
We learn how to foster and appreciate students’ notations for their richness and creativity. We also look at some of the possibilities that early work in creating notation systems might open up for students as they move on toward algebra.,Kenilworth Study: Pizzas In the fourth grade, the students encounter counting problems where the solutions cannot be built using standard manipulatives. As he invents his own notation systems, one student, Matt, builds on previous work to arrive at a solution

Students come up with a surprising array of strategies and representations to build their understanding of a real-life calculus problem—before they have ever taken calculus.,In a voluntary two-week summer workshop, high school seniors from Kenilworth and New Brunswick work on a real-life problem ("The Catwalk") based on Eduard Muybridge's sequence of 24 photographs of a cat in motion. The question, “How fast is the cat moving in frame 10 and frame 20?,” deals with some of the fundamental idea

Take Off with Paper Airplanes
This lesson introduces students to the art of designing an airplane through paper airplane constructions. The goal is that students will learn important aircraft design considerations and how engineers must iterate their designs to achieve success. Students first follow several basic paper airplane models, after which they will then design their own paper airplane. They will also learn how engineers make models to test ideas and designs.

Collisions and Momentum: Bouncing Balls
As a continuation of the theme of potential and kinetic energy, this lesson introduces the concepts of momentum, elastic and inelastic collisions. Many sports and games, such as baseball and ping-pong, illustrate the ideas of momentum and collisions. Students explore these concepts by bouncing assorted balls on different surfaces and calculating the momentum for each ball.
