- Abstract: Experiment with conductivity in metals, plastics and photoconductors. See why metals conduct and plastics don't, and why some materials conduct only when you shine a flashlight on them

- Abstract: Students gain an understanding of the difference between electrical conductors and insulators, and experience recognizing a conductor by its material properties. In a hands-on activity, students build a conductivity tester to determine whether different objects are conductors or insulators. In another activity, students use their understanding of electrical properties to choose appropriate materials to design and build their own basic circuit switch.

- Abstract: Detailed study of soil properties with emphasis on interpretation of field and laboratory test data and their use in soft-ground construction engineering. Includes: consolidation and secondary compression; basic strength principles; stress-strain strength behavior of clays, emphasizing effects of sample disturbance, anisotropy, and strain rate; strength and compression of granular soils; and engineering properties of compacted soils. Some knowledge of field and laboratory testing assumed.

- Abstract: WOW lessons are designed for infusion into the existing science curriculums for college freshmen and advanced high school students. The lessons use the aquatic environment and real lake data to explore basic science concepts through two different approaches: a directed study “Studying” and an inquiry “Investigating” approach. The directed studies allow students to apply and learn concepts through direct, guided experience. The inquiry lessons provide a more open-ended opportunity for students to discover the same concepts.
Each teacher's lesson plan provides general direction for guiding students to understand the topic through the directed study and the inquiry approach. Student lessons are organized into a thinking framework of six sequential components that are critical for improving scientific and technological literacy: knowledge base, experimental design, data collection, data management and analysis, interpretation of results, and reporting results. The teacher lesson plans follow the same format.
Lesson titles are simple and descriptive so that you may easily find useful materials. We recommend you begin by reviewing the student lessons that may be appropriate for your class. When you've found a student lesson to use, return to the menu below to review the associated teacher's lesson plan. There are tutorials to help you and your students get familiar with the site, they may be accessed from the menu below, or at the top of any 'teacher' page.
