Moyer, Richard; Everett, Susan – Science Scope, 2011
The United Nations has proclaimed 2011 as the International Year of Chemistry and, as part of that designation, has invited teachers worldwide to participate with their students in the Global Water Experiment (IYC 2010). Students have the opportunity to take part in four different water-related investigations to assess water quality and then share…

The pitcher throws the ball and the batter takes a mighty swing. Crack! The ball is hit on the sweet spot and soars to the outfield. Or, you hear a thud! This time, the ball dribbles along the infield ground and the batter's hands sting. Everyone who has played baseball or softball has probably experienced both of these outcomes. This may not seem…

Moyer, Richard; Everett, Susan – Science Scope, 2010
This article describes a lesson where students explore the absorbency of several towels with different weaves and weights. The lesson follows the 5E learning-cycle model and incorporates engineering in the sense of product testing with a focus on the relationship between the weave of a towel and its absorbency. The National Science Education…

The flashlight is a simple device that is composed of a lightbulb, usually two cells connected in series, a housing, a switch, and a reflector for the light. All flashlights essentially use these parts to complete a circuit that converts the stored chemical energy in the cells to light energy. In this lesson, students will take apart an…

Manufacturers often claim that their particular toothbrush design is better than the competitors, but is it? As a result, engineers must consider the economic issues involved with selling the products they create, as well as their functionality: to produce the best possible toothbrush regardless of cost, or the toothbrush that will sell the most,…

Every morning, many Americans start their day with a bowl of cereal. Some spend time while they eat breakfast reading the back of the cereal box, but few consider its size, shape, and construction, or realize that it was designed by an engineer. This article describes a lesson in which students design, build, and critique cereal boxes. The lesson…

Moyer, Richard; Everett, Susan – Science Scope, 2009
Meat thermometers can be awkward to use in terms of placement and avoidance of bones. Because of these problems, each year 30 million Thanksgiving turkeys have a built-in thermometer that pops up when the turkey is properly cooked. Turkey timers are an example of how engineering solved a common, everyday problem. The following 5E learning cycle…
