Great group activity that allows students to work together to identify independent and dependent variables. There are 9 stations - students read the scenario and fill in work sheet provided. I have them rotate every 2-3 minutes. Answer key provided. SMARTboard presentation included that has the scenarios and a PDF for you to print cards. I print each scenario on ans 8.5 x 11 card stock paper for durability as they get used. Two scenarios are deleted so that is why you see 2 numbers missing.
