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 discover that water molecules are polar, and that the polarity makes water a liquid under normal conditions (room temperature and average atmospheric pressure). In the previous activity, students built their model of a simplified cell with solutions on both sides of a membrane. In this activity students "turn up the magnification" to look at water molecules and their interrelations in a network of other water molecules, thus expanding their understanding of the properties of water and aquatic solutions.
Students will be able to:
Water molecules are small and highly polarized. Their polar nature gives water its unique, macroscopic properties. On a microscopic level, water is a network of these polarized molecules linked together by hydrogen bonds.
