Discussion Questions: Setting up a Fair Experiment with Balls and Ramps

You may find it useful to watch this video with a group of your colleagues and then discuss it together.

• How does Fessenden help her students understand the reasons for making a fair test and controlling variables?
• How does she help these students identify and target variables to control and change?
• Fessenden runs through the experimental procedure with her students first. Another approach might be to let these students construct the experiment for themselves. What do you think are the advantages and disadvantages of each approach?
