This online interactive module of 10 pages or frames integrates textual information, 3D molecular models, interactive molecular simulations, and embedded assessment items to guide students in understanding the copying of DNA base sequences from translation to transcription into proteins within each cell. The module divides the exercises in to Day 1 and Day 2 time frames. Teachers can view student assessment responses by assigning the module within a class created within the Molecular Workbench application. This Java-based module must be downloaded to each computer.

An interactive simulation in which students use a model of charged objects to explain how charges interact and construct an understanding of Coulomb's Law. It is concerned with comparing ions and neutral atoms. The model allows the user to investigate the relationships between sign of charge, magnitude of charge, and distance between ions. The model illustrates the operation of three types of electroscopes. Next it visually explores how a static charge can bend the path of a moving electron, and then graphically and numerically explores Coulomb's Law. Lastly a model that illustrates polarization of charge illustrates why a charged balloon is attracted to a neutral wall. The system allows students to enter their multiple choice and written answers throughout the activity and generate a report of their responses at the end even if they are not logged into the system.

Population Explosion is a computer simulation which allows students to manipulate factors to see what happens over time to a population of sheep within an enclosed field. As the simulation runs, a graph shows the dynamic relationship between the sheep population size and their primary food resource, grass. Students can control factors such as initial number of sheep, grass regrowth rate, gain from food, and birthrate. Predation is represented by a “reaper” button which may also be controlled. The speed of the simulation can be set so that students can see more clearly what happens over time, or collect data more quickly, depending on how fast the simulation runs. Directions and a suggested simulation sequence are provided along with prompts so that students can pause and consider their results. A space within the simulation is provided for students to record observations and answers to the prompts. For each step in this suggested sequence, students take a snapshot of graphs they have created and store them in an album. At the end of the activity analysis questions help students connect the activity to wild populations. An optional extension exercise is also suggested.
