Engineering entails more than knowing the way things work. What do economics and ecology, aesthetics, and ethics have to do with the shape of a paper clip, the tab of a beverage can, or the cabin design of a turbojet? How do the idiosyncrasies of individual engineers, companies, and communities leave their mark on projects from Velcro to fax machines to waterworks? Invention by Design offers an insider’s look at these political and cultural dimensions of design, development, construction, and production.

Students discover for themselves the key principles of the physical world around us: force and motion, friction and gravity, action and reaction, and work and power. They test a variety of surfaces for friction resistance, correlate weight to friction resistance, and investigate a variety of ways to reduce friction using wheels and rollers. With the materials included, students will explore variable inertia and use the mini-dynamics carts included to study the basics of elastic versus inelastic collisions.

From the concert hall to your classroom, laser lights are a captivating sight. Pitsco’s Laser Show – The Kit is a great way to take advantage of students’ interest in lasers to teach them soldering skills, circuitry, and how reflections and geometry are used to direct the laser’s path. The laser can project 40 to 50 feet.

This second-generation design offers a more streamlined look and construction, a simplified power source, and a laser. Varying the laser pattern is as simple as altering the speed and direction of two motorized mirrors.
