The site curates information from more than 55 databases, 2,100 websites, and 200 million individual pages.
The Science.gov homepage also features a news bulletin, video clips, and other science-oriented resources.
Eformulae.com: This site is a collection of scientific and mathematical formulas used in fields like engineering, physics, chemistry, and statistics. The layout is fairly rudimentary, but the materials are easy to access and the information is reviewed and edited by experts in these respective fields.
For each formula, all variables and operations are clearly defined. See the ‘Engineering Formulas‘ page as an example.
For fields with differing schools of thought, different formulas are housed in their own sections (as is the case with ‘Applied Mechanics‘, and others).
Biology Online: Registration is free on this site, which hosts digital books, article links, tutorials, and a dictionary of biology-related terminology.
The site's forum lets users post questions and take part in biology-oriented discussions.
Another popular feature of the site is a monthly blog that covers topics like allergy season, botany, and obesity.
Published authors are invited to share their work on the site and receive feedback from other registered users.
Biology Reference: Simple and easy-to-use, this alphabetized directory of biology topics features detailed encyclopedic entries written by on-site authors.
All articles feature a bibliography of sources and comment field for readers to provide feedback.
A significant amount of interlinking between entries allows users to browse similar topics with relative ease.
Ptable: This illustrated guide to the Periodic Table of Elements features definitions of all elements, as well as information related to orbitals, isotopes, compounds, and other fundamentals of chemistry.
All element definitions are linked to their corresponding Wikipedia pages.
The interactive diagrams allow users to toggle boiling/melting point, electronegativity, density, and other comparative aspects of different elements.
ChemnetBase: This database of reference materials includes guides to specific scientific topics, such as the ‘Combined Chemical Dictionary‘ and the ‘Dictionary of Drugs.' Subscriptions to the site are not free, but all new members receive a free thirty-day trial.
The site also includes a section dedicated to ‘Librarian Resources.'
‘Subject Collections‘ of e-books pertaining to 43 different professional fields are housed on individual pages.
A digital copy of the ‘CRC Handbook of Chemistry and Physics' is viewable in the read-only format, while hard copies are available for purchase on the site.
Thomas Adewumi UniversityChemtutor: Recognized by the National Science Foundation and SchoolZone, Chemtutor provides study guides related to 16 generalized chemistry subjects, including elements, kinetics, gases, and acids/bases.
All lesson plans are illustrated, and feature practice problem sets for new learners to complete.
The site features a search tool that allows visitors to browse different lesson plans for specific topics.
The site's link directory is powered by PSIGate, a search engine that exclusively yields pages related to the physical sciences.
PhysLink: This collection of learning tools related to physics and astronomy includes a directory of articles sorted by general topic, resources for educators, a job board for aspiring physicians and astronomers, and an online store.
The Physics and Astronomy Directory contains lists of university departments, student and professional associations, academic journals, and other resources pertaining to these two subjects.
Visitors can pose questions and receive feedback from experienced professionals, thanks to the ‘Ask the Experts‘ tool.

The ‘Fun‘ section features puzzles, cartoons, humorous articles, and other recreational materials.
Physics Help: Dr. Konstantin E. Nikitin maintains this compilation of study guides for different physics-related topics. Although the site is incomplete, Dr. Nikitin urges visitors to send him questions related to fields that do not have study guides at this time.
Each guide contains diagrams, tables, formulas, images, and other media to bolster the text.
Three appendices are available: Physics Constants, SI Units and Symbols Used, and Vectors.
MinutePhysics: Created and run by Henry Reich, this Youtube channel presents short videos geared towards educating viewers–students and non-students alike–on the wide range of physics topics.
They are presented in a style and language that simplifies complex topics without dumbing them down.
Review the following examples of test questions from a sociology class. The first question only requires that you recall a definition, which you can do well through rote memorization techniques, such as flash cards. The remaining questions require you to make connections or conclusions that may not have been directly presented by your professor or your text book.
To correctly answer test questions like those in the example, you must create study guides that will help you:
Condense course material into smaller amounts of information that are easier to remember.
