using the scientific method designing a controlled experiment

based on the hypothesis below answer the following questions please.

Hypothesis: Water will diffuse from a region of high water potential to a region of low water potential when both solutions exhibit a water potential gradient and are separated by a semi-permeable membrane because water movement occurs along the water potential gradient.

  1. What is your independent variable? (what you are manipulating or testing)
  2. What is your experimental group?
  3. What is your control group?
  4. Is your independent variable continuous data (e.g. time, distance, length, etc.) or discontinuous data (e.g. categorical data like color, binned data like small, medium, large categories, etc.)
  5. What will be similar about how you will treat your experimental and control groups? (i.e. what are your controlled variables)
  6. What will be different about how you treat your experimental and control groups? (i.e. what is your experimental variable)
  7. What is your dependent variable and how will you measure it? (the outcome you are measuring; the duration, interval of sampling, unit of measure, etc.)
  8. What do you predict will be the relationship between your independent and dependent variables? (i.e. what do you think will happen if your hypothesis is supported, not supported?)
  9. Sketch or describe a graph of your expected results if your hypothesis is supported. Remember that independent variables are plotted on the x-axis and dependent variables are plotted on the y-axis.
