  1. Week 3 Warm Up 9/5/13 Pg. 14/15 A student is going to experiment on the following question: Will the amount of salt in water help a toy boat float higher in the water? 1. What is the manipulated(independent) variable? 2. What is the responding(dependent) variable? 3. What are some of the controls (parameters) for this experiment? (what do we have to control to make the experiment fair)? 4. What would be an appropriate hypothesis for this experiment?

  2. Week 3 Warm Up 9/6/13 Pg. 14-15 part 1 Identify the manipulated and responding variable in each question: 1. Will using sharper scissors help you cut straighter? 2. Will the weight of a rocket effect how high it flies? 3. On which axis of the graph do you put the manipulated variable? 4. What type of graph should you make if you have collected the following data?

  3. Week 3 Warm Up 9/6/13 Pg. 14-15 part 2 What is the control group in an experiment? Think about what a control is. 2. What are all the parameters (variables and controls) in the following experiment: Does sugar water help a plant grow faster? 3. Which of the following would NOT be a parameter? The amount of sugar, the height of the plant, the amount of water, the color of the leaf 4. Where does the dependent (responding) variable go on a graph?
