Students are introduced to the concepts of stress and strain with examples that illustrate the characteristics and importance of these forces in our everyday lives. They explore the factors that affect stress, why engineers need to know about it, and the ways engineers describe the strength of materials. In an associated literacy activity, while learning about the stages of group formation, group dynamics and team member roles, students discover how collective action can alleviate personal feelings of stress and tension.

To introduce the two types of stress that materials undergo compression and tension students examine compressive and tensile forces and learn about bridges and skyscrapers. They construct their own building structure using marshmallows and spaghetti to see which structure can hold the most weight. In an associated literacy activity, students explore the psychological concepts of stress and stress management, and complete a writing activity.

Swing in Time

0.0 stars

Students examine the motion of pendulums and come to understand that the longer the string of the pendulum, the fewer the number of swings in a given time interval. They see that changing the weight on the pendulum does not have an effect on the period. They also observe that changing the angle of release of the pendulum has negligible effect upon the period.

0.0 stars

Students explore how pendulums work and why they are useful in everyday applications. In a hands-on activity, they experiment with string length, pendulum weight and angle of release. In an associated literacy activity, students explore the mechanical concept of rhythm, based on the principle of oscillation, in a broader biological and cultural context in dance and sports, poetry and other literary forms, and communication in general.

0.0 stars

To learn about the concept of center of mass, students examine how objects balance. They make symmetrical cut-outs of different "creatures" and experiment with how they balance on a tightrope of string. Students see the concept of center of mass at work as the creatures balance.

0.0 stars

Students begin to explore the idea of a force. To further their understanding of drag, gravity and weight, they conduct activities that model the behavior of parachutes and helicopters. An associated literacy activity engages the class to recreate the Wright brothers' first flight in the style of the "You Are There" television series.

Contamination in drinking water sources or watersheds can negatively affect the organisms that come in contact with it. The affects can be severe causing illness or, in some cases, even death. It is important for people to understand how they can contribute to the contaminants in drinking water and what treatment can be done to counter these harmful effects. Students will learn about the various methods developed by environmental engineers for treating drinking water in the United States.
