In this egg lab experiment, students will immerse an egg in three different substances: vinegar, syrup, and water, for 2-3 days each. They will measure and record the volume of liquids added and removed, as well as the egg's mass at each stage. By analyzing the data, students will define the dependent variable, identify the solutions' tonic nature (hypotonic, hypertonic, isotonic), and calculate the change in mass. The experiment culminates in a data graph that illustrates the findings, enhancing understanding of osmosis and its effects on cells.

Egg Lab In this lab you will submerse an egg into three substances for 2-3 days each. First, you will place the egg in 100 ml of vinegar. Next, you will place the egg into 100 ml of syrup. Finally, the egg will be immersed into 100 ml of H2O. You will need to record the amount of liquid you place into the cup, as well as the amount of liquid taken out of the cup. Mass of the egg will need to be taken at each step.
Egg Lab What is the operational definition of the dependent variable in this lab? How did you conclude whether the solutions you tested were hypotonic, hypertonic, or isotonic? What were the independent and dependent variables in this experiment? Calculate the change in mass of the egg. Explain how this may relate to your findings. Using your data table – Graph your data NEATLY!
