Growing Barley for Use in Biosynthesis Experiments
Students attempt to determine the optimum growing conditions for barley. They assess the effects of a number of substances such as ammonium chloride and urea on the plants
Curated OER
Window Gardens
Young scholars use a plastic sandwich bag containing a damp paper towel taped to a window as a model system to observe the germination and early growth of radish seeds. They are challenged to pose a question about seed germination and...
Curated OER
Every Breath You Take
Learners study acids and bases and the uses of indicators. They interpret the actions of an indicator to conclude that bromothymol blue turns yellow in the presence of a weak acid.
Curated OER
"Publication" of Scientific Papers And Posters
Students create and display a scientific poster in the same format that scientists use at a research symposium. They compile data and make conclusions about the classification of the Arizona Hedgehog Cactus as an endangered species. ...

WET Science Lesson #5: Pass the Salt Please! (How Road Salt Affects Wetlands)
As an anticipatory set, biologists listen to the story of Ruth Patrick, a scientist who used algae to detect water quality. They observe a demonstration of osmosis and diffusion. In their lab groups, they place Elodea stalks in...
Nuffield Foundation
Identifying the Conditions Needed for Photosynthesis
Budding biologists often ask how scientists know what they do about different topics. In the lab described here, they have a chance to find out first-hand about the requirements for photosynthesis. Three sequential investigations are...
