Strong as the Weakest Link
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.

Building-Stone Geology
This laboratory activity gives an example of the creativity required when teaching non-native rock types. In order to study igneous and metamorphic rocks in central Florida (a huge area consisting solely of sedimentary rock), geology students examined building stones in downtown St. Petersburg. Each student picked a particular rock type used in a particular way (structure, decorative facade, etc.), performed geologic tests on it, read up on its properties, history, and uses, and prepared a paper

Science In Focus: Energy
Interview with Stephen Connors about limited sources of energy and the importance of using renewable sources.,The interviewee responds to the question, "Why does the U.S. use more energy per capita than other countries in the world?" He talks a bit about how energy is taxed less in the U.S. so it's cheaper, but he also goes on to contrast patterns of energy use in America and Europe. He explains how cities planning was pro-founding affected by the availability (or lack of availability) of the

Uniform convergence and pointwise convergence
The aim of this material is to introduce the student to two notions of convergence for sequences of real-valued functions. The notion of pointwise convergence is relatively straightforward, but the notion of uniform convergence is more subtle. Uniform convergence is explained in terms of closed function balls and the new notion of sets absorbing sequences. The differences between the two types of convergence are illustrated with several examples. Some standard facts are also discussed: a uniform
