In an investigation called "Shape It!" learners craft tiny boats out of clay, set them afloat on water and then add weight loads to them, in order to explore: how objects stay afloat in water; what the relationship is among surface tension, buoyancy, density and displacement; and how shape, size, and type of material affect an object's ability to remain buoyant. The introductory text discusses how heavy steel ships can float on bodies of water like rivers, bays and oceans.

How do strong and weak acids differ? Use lab tools on your computer to find out! Dip the paper or the probe into solution to measure the pH, or put in the electrodes to measure the conductivity. Then see how concentration and strength affect pH. Can a weak acid solution have the same pH as a strong acid solution?

Examines the urban environment as a natural phenomenon, human habitat, medium of expression, and forum for action. Subject has two related, major themes: how ideas of nature influence the way cities are perceived, designed, built, and managed; and how natural processes and urban form interact and the consequences of these for human health safety and welfare. Description from the course home page: This course explores the urban environment as a natural phenomenon, human habitat, medium of expression, and forum for action. The course has several major themes: how ideas of nature influence the way cities are perceived, designed, built, and managed; how natural processes and urban form interact and the consequences for human health and welfare; how planners and designers can shape the urban natural environment. Each student researches and presents a case, either historical or an example of contemporary theory and practice.

Highlights of this course include: Major biological, chemical and physical components of the agricultural systems The scientific basis for understanding these systems and their management How has science influenced policies related to agriculture, food safety and environment in the United States? How have the policies evolved over time in the US? What has worked and what has not; what are the reasons and what are the consequences? Beyond science, what other factors influence policies? How do we link what we learn to ecological agriculture? How do we use what we learn for policy analysis?

This Ocean Explorer lesson plan (PDF) explores the questions: What colors, if any, are visible down in the deep sea? What is bioluminescence? Students will learn about white light (visible light), the quantity and quality of light as related to ocean depth, the difference in water penetration between red light and blue light, bioluminescent organisms, the color of most bioluminescent light, and why organisms bioluminesce. The lesson plan includes background information and keywords, a list of materials, teacher preparation instructions, learning procedures, related links, evaluation and extension ideas, and correlation to the national standards.
