Pre-lab Questions

1. A student is trying to determine how fast their turtle runs around a track. If they want to graph the time the turtle walks, in seconds, compared to the distance walked, in meters, which variable should be plotted on the x-axis? Briefly explain why.

3. According to your plots, how tall should Pea Plant C be at week 13? (Hint: Use your trendline equations. Consider what “y” and “x” represent in the equation based on the graph you made, and use your equation to plug in for week 13 and solve for height). Be sure to include units, and briefly explain how you found your answer.

Calculations/Work

Add a screenshot of your Excel graph below. Make sure it is correctly formatted as the instructions direct.

How to take a screenshot (use this website if you get stuck):

If you are on a Windows device, hold down (Windows key) + (shift), then press (s). Use your mouse to draw a rectangle around your graph, then (ctrl) + (v) below to paste the image.

If you are on a Mac, hold down (cmd) + (shift), then press (4). Use your mouse to draw a rectangle around your graph. The image should be saved as a file on your desktop. Click and drag it below to paste it into the document.
