Diffusion Assessment
The goal of the Molecular Logic project is to improve the ability of all students to understand fundamental biological phenomena in terms of the interactions of atoms and molecules. The Molecular Logic project aims to do this by enhancing biology courses with guided explorations of powerful atomic and molecular computational models. These models are embedded in an easily implemented database linked to both typical textbooks and standards.
This is a performance assessment for an initial understanding of molecular dynamics models and should follow an activity or lab exercise on diffusion. Students are asked to predict what will happen to perfume molecules when a bottle of perfume is spilled in a room. After the prediction, the students click on a simulation, which shows the perfume molecules diffusing. The students can adjust room temperature and observe the changes. They are given the opportunity to capture a snapshot of the simulation at any given point and type in their observations. Questions are answered and captured in a student report that can be saved to the website or printed.
