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.
