Important! If you cannot launch anything from this database, please follow the step-by-step instructions on the software page.
Please Note: Many models are linked to directly from within the database. When an activity employs our scripting language, Pedagogica, as do some of the "guided" activities, the initial download may take several minutes. Subsequent activities will not take a long time. See this page for further instructions.
Students learn that opposite charged particles attract to each other and particles with the same sign of charge repel each other. In addition they discover out that Coulomb's Law can be calculated by looking at the distance and the charge of each particle. They end the activity looking at the screening effect in systems such as the watery environment of cells.
Students will be able to:
• Explain how a neutral atom can become a charged particle, an ion.
• Define Coulomb forces as a result of like charges repelling each other and unlike charges attracting.
• Determine that the force generated between atoms is dependent on the amount of charge they carry and the distance between them.
• Explore the mathematical relationship described in Coulomb equations.
• Explain polarization in terms of charge redistribution.
• Give an example of how screening is at work in a biological system, such as a cell.
