General Chemistry at Purdue

• Purdue University offers an online environment to discover general chemistry. Students have the option to ascertain information on molecular structure, states of matter, atomic orbital, elements, compounds and mixtures. Most lessons offer an interactive microscopic view to illustrate the topics. For instance, by selecting the "States of Matter" link, students can view gas, liquid and a solid under a microscope. Then, students learn how gas, liquid and solid particles differ. In addition, students may review a table that summarizes the properties.
  
  

Creative Chemistry

• High school students may test their chemistry knowledge at Creative Chemistry. Students find puzzles, crosswords, quizzes and molecular models to review. For an example, select one of the interactive chemistry crosswords, such as "organic chemistry," "acids, alkalis and salts," "rates of reaction" or "chemical families." Expect clues, such as "O (6)." Type the word "oxygen" in the box. In addition, students can review a molecular model for the following four different substances: sodium, chloride, diamond, graphite and iodine.
