Chemistry: Molecular Models
The following web sites have instructions on how to download and use the Chime plug-in for working with three-dimensional molecular models. Find out how wireframe, stick, ball and stick, and space filling models vary from each other and what the advantages and disadvantages are. Learn about Valence Shell Electron Repulsion Pair (VSERP) theory and view VSERP molecular models. Includes images, 3D interactive models, animations, movies, quizzes, and lesson plans.
Here is a web site with interactive models of DNA and RNA, lesson plans for teachers, and questions for students. Find out what browser to use for viewing 3D Chime models. Click on the "Chime Installer" link for step-by-step instructions how to register, download, install, and use Chime. The registration and download are free and takes about five minutes to complete. NOTE: The free Chime plug-in is required. NOTE: The site leads to websites with a message board.
This page has a link to a 3D model of a complex macromolecule. Scroll down the page and select the "Preview DRuMS (no Chime)" link to lunch another page. The page has also a link to "Biochemistry in 3D" with more molecular models which require Netscape Communicator 4.
This online tutorial can help students realize why 3D models are important for displaying molecular structures and how to view them online properly. Learn differences among wireframe, stick, ball and stick, and space filled models. The three parts of the site include demonstrations of using models, questions for kids, and an activity sheet. NOTE: The free Chime plug-in is required.
Learn how to assemble molecular models. Click on the "Content" button or link to advance to a page with links to pages with interactive models, instructions, assembling demonstrations, and examples. Students also can use a forward or rewind buttons for navigation on the site. NOTE: The free Chime plug-in is required.
Find structures of small molecules such as water, carbonate, and carbon dioxide. Scroll down the page and click on the icons with more complex molecules to view them. NOTE: The free Chime plug-in is required.
This site includes interactive and still images of molecular models. Select green buttons in the middle or links on the left to view images of molecular structures. NOTE: The site leads to websites with ads.
This site is a searchable database of chemical structures and property predictions. Results produce the empirical formula, molecular weight, and masses of chemicals. Articles and links to articles can be read for further information. NOTE: This site includes ads.
