Divide your chemistry or environmental science class into two groups. Each group tests water samples from a river for the concentration of phosphorus using a different method. With chemists, you can use this activity as they learn to use...

Students list sources of phosphorus in soil. They explain how phosphorus is removed from the soil and used by plants. Students list the symptoms of insufficient or excess phosphorus. Students perform experiments to examine the effect of...

Students examine specific skills in assessing water quality from a holistic approach. They assess the health of a local watershed and identify problems in the local watershed and suggest remediation.

In this chemistry worksheet, students find the formula weight for each of the substances listed on the sheet. Then they find the percentage composition as indicated.

Observe two different water samples and write down observations. Write a paragraph which predicts the relative amounts of nutrients, nitrates, and phosphates in the water samples. Compare water samples under a microscope.

In this computer worksheet, students use ViewPoint's forward and backward arrows, and the search tool to locate information given about minerals and vitamins. They load the Vitamins datafile and use the search tool to respond to five...

Students determine how the various levels of minerals in the soil, as well as the pH of the soil, affect the growth of plants in these plant growth experiments.

Students are introduced to biomolecules and their roles in livin systems. They are introduced to the "Elements of Life." Students write down and define the "Elements of Life." They are asked why they think those elements are essential...

First graders examine body systems and demonstrate their competency in a quiz game show. Lessons cover the brain, heart, lungs, digestive system, muscles, and bones. Students , in teams, answer teacher-created questions in the game.

Students are given standard elemental nutrients, identify plant nutrient requirements based on criteria outlined in assessment instructment. They, are given standard elemental nutrients, provide all means and chemical symbols of plant...

Young scientists roll up their sleeves and get a little dirty in this three-day earth science investigation. Following the scientific method, children monitor the growth of algae in pond water samples in order to determine...

Do great gardeners really have green thumbs—or just really great soil? Environmental scholars discover what makes Earth's soil and soil quality so important through research and experimentation. Learners also develop an understanding of...

Students perform soil tests for pH, nitrogen, phosphorus, potassium, composition and water percolation rate and assess the conditions in the schoolyard.

Students are able to use a secchi disk to measure the turbidity of water by determining the depth at which the sechi disk is no longer visible and using the data in a formula to quantify the results. They are able to use Vernier probes...

Students are introduced to how nitrogen and phosphorus metabolize in feedlot cattle. Using the Internet, they discover the recommended requirements for cattle to minimize overfeeding them. They develop dietary strategies that might...

This is not they typical set of teacher instructions. It is an organized chart of the important organic compounds. For each, the involved elements, the name of the building block monomers, the names of polymers, extra information, and a...

Ninth graders practice how to format and enter data into an Excel spreadsheet, make a graph, and interpret graphed data. They recognize how the pollution in the Hudson River has changed over time, and explain the consequences of these...

Explore genetically modified foods through various experiments. In this biology lesson, students discuss the safety issues related to GMF's. They conduct a PCR analysis to identify the presence of genetic modification.

The biogeochemical cycle ... no physics? The fourth installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program introduces the biogeochemical cycle by having pupils simulate movement between Earth's...

How does water pollution affect the environment? Provide your class with the resources to answer this question as they learn about eutrophication and ecosystem changes. Over two weeks, they simulate the effects of pollution on the...

Compare and contrast macromolecules made from the same elements. Young scholars learn how the structure of a molecule has as much influence on a compound as the elements in the molecule. They experiment with molecular model kits to...

Students describe environmental interrelationships using list of criteria. They are able to explain organism interaction, based on definitions provided. Also, students can use references and worksheets, to describe effects of pollution...

In this gas law worksheet, students use the Universal Gas Law and van der Waals equation to calculate volume and molar mass of gases. This worksheet has 6 problems to solve.

The theory that adding iron to ocean water may increase phytoplankton ability to remove carbon dioxide from the atmosphere is examined. The Monterey Bay Aquarium Research Institute is monitoring conditions off the California coast to...
