When additional information is needed by the student to complete their lab assignment, it can be presented in the following ways:

  • Directly on the webpage as part of the lab's HTML - ancillary information that is specific to the lab being completed can be placed directly on the lab webpage. Important directions / clarifications appear as text that may be enlarged, bolded and colored to "stand out" to the user. In addition, information contained in tables, images, webpages, videos, and animations can be "embedded" in the webpage.
  • Under a "More Information" link on the webpage - to save space and eliminate clutter on a webpage, the items mentioned above (tables, images, webpages, videos, and animations) can be "hidden" under a "More Information" link. Click this link below to "reveal" a spectrometer animation of Beer's Law.

    In the interactive animation, the red light (incident beam) is shining on a green solution. Click/drag the "Drag" slider to see the intensity of the attenuated light as the percent transmittance changes. To alter the incident beam and solution color, click on the various light colors (upper left). For More Information, click the color wheel (upper right).

    Click the Hide Information link below to collapse this section.
  • Under the "Reference Materials" link - located at the top of every Chem21Labs webpage, this link displays information that is commonly used to complete labs and homework assignments.
