Scenario A:
During an experiment at a high school biology classroom, a group of students decide to perform an investigation. For their investigation, they fill up four different dialysis bags with 0.2 M solution and place them in four different beakers containing different concentration solution as you can see below. The students want to find out which dialysis bag will result in no mass change.
A. Write a question that could be the basis of their investigation.
B. What is they hypothesis for this investigation?
C. Identify the independent, dependent, and constant variable.
Independent Variable:
Dependent Variable:
Constant Variable:
D. Describe three essential steps in the procedure needed to conduct your new valid investigation about osmosis and movement of water. The procedure must be written so that students in another science class could clearly follow your instructions and successfully complete the experiment.
1.
2.
3.
E. Construct a data table in the space below that other students could use to record and analyze the data collected during the new experiment related to osmosis and movement of water. Be sure to label rows and columns appropriately and to include units if necessary.
F. Use all data from the data table to construct a multi-line graph on the grid below. Be sure to provide an appropriate title, labeled axes with appropriate units, appropriate number scales, and correctly plotted data with a key.
