	CONTENT: This project offers a molecular simulation engine for "generating model-based activities, and for annotating and sharing them among students".
	AESTHETICS: The site is attractive and user friendly. A text only/accessible version is available (link at the bottom of the page). Necessary software can be downloaded at the site free of charge.
	ORGANIZATION: Navigation through the site is easily accomplished with the top navigation bar that includes links to the major sections of the site. Text links are also included on the main page of the site.
	REVIEW: The Molecular Workbench "facilitates student learning through the use of guided inquiry about the connections between microscopic and macroscopic properties of material." Five units (modules) are available that focus on topics in physical science, chemistry, and biology. Topics include: kinetic energy, states of matter; aquatic solutions in and around cells; monomers and polymers; and protein shaping. Each module includes a framing question or problem, and a sequence of activities such as, how hot air balloons work, how superballs are like atoms, what matter is made of and rainstorm in a bag; that lead to mastery of specific concepts. These activities give students multiple opportunities to solve problems using the computer models as well as participate in some hands-on laboratory work. Additionally, the research results on the "effectiveness of the molecular dynamics models with regard to helping students explain and reason about atomic-scale phenomena" are available.
