Daisyworld Interactive Activity
Students use a JAVA interface design to explore the Daisy World model. The model is intended to illustrate a mechanism by which biota might optimize their abiotic environment by means of negative feedback. The model does not attempt to describe all of the possible mechanisms and feedbacks which might influence the ways in which the plants and climate develop. Instead, it is an heuristic model, that seeks to describe the ways in which this mechanism might work. The original model was developed by

Mendel's experiments
In this web lab, Gregor Mendel directs students through interactive virtual experiments. Students experiment with pea plants to discover how the seven pairs of traits that Mendel studied are inherited. The lab can be completed linearly, or students can move to a particular segment using the Sections menu. After they observe pea plants and infer the number of traits present, students perform five plant crosses. Mendel instructs students to search for patterns in the transmission of traits. Next,

What Is Service Learning?
Learning in the context of real-world problems through activities that not only promote student learning but also serve the public. Environmental and analytical chemistry courses provide a background for using scientific skills to work with the community and gain an understanding of a scientist's role in society. A group of faculty was convened to examine how service learning can best fit into chemistry instructional programs.
