Do Human Practices Affect Water Quality?
Students determine if human practices have any noticeable effects on the quality of stream life as measured by the presence of certain macroinvertebrates. They collect, preserve and identify macroinvertibrate samples and quantify the data.
Curated OER
Greenhouse Effect
Students identify greenhouse gases. They explain why perfluorocarbons are a bad alternative to chlorofluorcarbons. They determine both the least and most influential greenhouse gases.

Sculptural Statistics
Students conduct an experiment to determine the frequency of pulling various parts of an ancient Greek sculpture out of a hat.
Curated OER
Carpooling and the Environment
Students investigate carpooling and determine to what extent it occurs in their community for a carpool challenge. In groups, students create a survey then collect, calculate and record data to determine how much pollution could be...
Curated OER
Finding and Measuring What You Can't See
Students determine how scientists measure pollutants in food and the environment. Students discover how scientists remove one material based on its physical properties. Students figure out how much of a pollutant is present after...
Curated OER
Molar Ratio
Students conduct an experiment in which they react sodium bicarbonate with hydrochloric acid to determine the molar ration between the two reactants. Students must write correct formula and a balanced chemical equation and explain how...
Curated OER
Watershed Analysis
Students conduct a regional watershed analysis of an area of their choosing. Using on-line data and their personal knowledge of the area, they determine the annual hydrologic budget and teach the class about "their" watershed.

Fractional Parts Using an Area Model
Learners explore multiplying fractions and their relationship to parts of a whole. They draw and shade fractional parts to show parts of a whole and fractional parts of a fraction. Pupils also use an Internet site for interactive practice.
Curated OER
Dividing with Fractions
Use paper strips or models to relate division problems to division of fraction problems. Since the materials can be broken up, it helps them to show how they can complete repeated subtraction with fractions and not just whole numbers.
