Consider the graph showing the height of plants over time, based on sunshine per day. 180 Key: 1 Hour of Sunlight Height (mm) 80 100 120 140 160 888 60 40 20 01 4 5 6 7 8 9 10 11 Day plant measured 3 Hours of Sunlight 6 Hours of Sunlight 9 Hours of Sunlight a) What does the y-intercept represent? b) What are the units of slope in this graph? c) Over the first 6 days, which plant: a. Grew really fast but then growth slowed? b. Growth rate increased? c. Growth rate stayed about the same and d) If someone told you that they chased away a cat that was digging in one of the plants on one of the days, make your guess of which day and which plants. How do you know? e) If you heard that there was a particularly cold day: a. Which day would you guess? Why? b. One plant was nearest the warm house. Which one? Why? c. One plant was more impacted than the others by the cold. Which one? Why? f) What range of time (between days) has the fastest growth for a given plant? Identify the plant, the day, then calculate the rate of growth (showing all work and units): g) What range of time (between days) has the most dramatic drop in height in the above graph?

For each experiment below: think about independent vs dependent variables, then specify appropriate titles (including units for axis titles). a) A student wanted to test how the mass of a paper airplane affected the distance it would fly. Paper clips were added before each test flight. As each paper clip was added, the plane was tested to determine how far it would fly in meters. Graph Title: X-axis Title: Y-axis Title: b) A technician wanted to see if a spring could be used on his car. He added various weights to the spring and measured how much the spring compressed. He used weights from his home gym (plates in kg) and a ruler (in cm). Graph Title: X-axis Title: Y-axis Title: c) A scientist studying new winter tires wants to determine their stopping ability. She has an assistant drive a car at various speeds 20km/hr, 30km/hr, 40km/hr... etc. and measures their stopping distance in meters. Graph Title: X-axis Title: Y-axis Title: 7. Draw a good "best fit line" through each set of data (representing the data). If a there's a situation where a best fit line doesn't represent the data well, just write "no trend."
