Go To Activity

Follow the link above to start or download this activity.

This Activity Requires:

Java 1.5+ - Java 1.5+ is available for Windows, Linux, and Mac OS X 10.4 and greater. If you are using Mac OS X 10.3, you can download MW Version 1.3 and explore within it instead.

Test your system to see if it meets the requirements

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.

	Overview and Learning Objectives This is an advanced multi-model unit that introduces chemical reactions and transitional states. It ends with the making of water in the 2H2+O2=2H2O reaction. return to top



	Central Concepts Key Concept: Chemical reactions follow pathways of minimum energy. Additional Related Concepts Physics/Chemistry Atom Bonds Breaking bonds Catalyst return to top



	Benchmarks and Standards AAAS THE PHYSICAL SETTING: THE STRUCTURE OF MATTER - The rate of reactions among atoms and molecules depends on how often they encounter one another, which is affected by the concentration, pressure, and temperature of the reacting materials (Full Text of Standard) NSES Physical-Science: Chemical Reactions - 2 Chemical reactions may release or consume energy (Full Text of Standard) Physical-Science: Chemical Reactions - 3 A large number of important reactions involve the transfer of either electrons (oxidation/reduction reactions) or hydrogen ions (acid/base reactions) (Full Text of Standard) Physical-Science: Chemical Reactions - Catalysts, such as metal surfaces, accelerate chemical reactions (Full Text of Standard) return to top
