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. (less)

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? (less)

Plants and animals that live in water create some amount of acid in the water. The carbon dioxide that plants and animals release into the water makes the water acidic and unsafe for living organisms. This is why the water of captive aquatic animals and plants must be changed often. (less)

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? (less)

Large amounts of nutrients from agricultural runoff and pollution cause increased growth of algae. Algal blooms cause other organisms to die because the algae uses up all the oxygen in the water to grow. Eventually, this body of water will have no life in it. (less)

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.
