Here's a five-star lesson plan in which inquisitors conduct sophisticated experimentation with cellular respiration in plant seeds. Placing seeds in a closed system they measure the amount carbon dioxide produced and relate it to...

Students explore the concepts of mean and variance. They observe properties of materials to their basic atomic or molecular structure. Students use spreadsheet software to record, tabulate and analyze collected information.

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.

Students observe and record the changes they see when adding heat and cold to objects. In this changes lesson plan, students experiment with different objects and see if heat and cold change the makeup of the object. They then record...

Pupils count nematodes, cestodes and crustaceans on approximately one-hundred and fifty fish. They fill out autopsy reports for external and internal parasites then complete and discuss guide questions to make inferences about parasite...

Students survey and dissect as many fish as possible. They count nematodes, cestodes and crustaceans on the fish, fill out autopsy reports, and transfer data to a chalkboard data table. Students graph the results of the entire class...

Students participate in an experiment in which they gather and examine particiles in the air. They place pollution detectors at different locations and identify problem areas. They discuss how engineers can use this type of information...

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...

Pupils compare the population of insects in different microclimates. In this biology lesson, students collect data using probes to tabulate temperature and soil data. They predict how certain parameters change as an area goes...
