For this assessment you will conduct a kitchen science experiment in which you study the movement of materials into and out of cells. Individual cells are generally too small to see; however, a chicken egg is actually a single cell. Please note that on the whole this lab will take you 3 days to complete. However, there is less than 1 hour of ‘hands-on’ work on the first and last days.
Use the Membrane Lab procedure for your experimental set up.
When complete, write a lab report in MLA format that includes the following sections.
Use this example to give you an idea of how your experiment may look in progress, and to help with completing your lab report.
Basic Requirements (the assignment will not be accepted or assessed unless the follow criteria have been met):
embrane Hands-on Laboratory: Part of Competency 5 Performance Assessment
4 Eggs, uncooked
10% salt solution
Soda, sports drink, or ‘fitness water’ of your choice
Containers for eggs (clear plastic cups work well)
Ruler and/or measuring tape (a fabric/clothing one will work best)
A note about this procedure:
It is possible your egg(s) will float in step 7. That is okay; just be sure there is plenty of liquid to cover them if they should sink.
