Lab Procedures and Activities

General Lab Procedures

  • It is important to remove the solvent front from the setup before it runs off the page. This is essential for accurate measurements and observations.

    • Timing is Crucial: Take it out relatively soon to allow it to start drying. This helps in taking measurements clearly.

    • Drying Equipment: Place the removed piece on paper towels on the side to allow drying.

Lab Activities and Measurements

  • Students are encouraged to look at their previous simulations while working on current tasks.

  • Post-measurement activities include:

    • Revisiting the simulation lab to collect data or complete simulations.

Clarifications and Visual Aids

  • There was a discussion regarding using the term "Crayola" and its correspondence with measurements, potentially confusing light and small items with labeling and categorizing elements.

    • Crayola Reference: The Crayola may refer to a visual marker that helps distinguish between the sizes or types of items.

  • The concept of "greater than" and "less than" parallels the use of an alligator eating the larger or significant number,

    • Specifically, if one number was taller than another, the alligator (which represents the greater number) would eat the taller (greater) item.

Clean-Up Procedures

  • After measurements are taken, it is vital to maintain cleanliness in the lab:

    • Ensure tables are cleaned up, and all papers are appropriately placed.

    • Liquid waste should be disposed of down the drain as per lab safety protocols.
