Question

chemistry controlled experiment and graphing worksheet
using the following data, answer the questions below and then construct a line graph in the grid.

depth in meters | number of bubbles / minute plant a | number of bubbles / minute plant b
2 | 29 | 21
5 | 36 | 27
10 | 45 | 40
16 | 32 | 50
25 | 20 | 34
30 | 10 | 20

Explanation:

To construct the line graph, we follow these steps:

Step 1: Determine the Axes

• X - axis (Independent Variable): Depth in meters. The values are 2, 5, 10, 16, 25, 30.
• Y - axis (Dependent Variable): Number of Bubbles per minute. The range of bubble counts is from 10 to 50, so we can set the scale of the Y - axis appropriately (e.g., from 0 to 60 with an interval of 5 or 10).

Step 2: Plot the Points for Plant A

• For depth = 2 meters, number of bubbles = 29. Plot the point (2, 29).
• For depth = 5 meters, number of bubbles = 36. Plot the point (5, 36).
• For depth = 10 meters, number of bubbles = 45. Plot the point (10, 45).
• For depth = 16 meters, number of bubbles = 32. Plot the point (16, 32).
• For depth = 25 meters, number of bubbles = 20. Plot the point (25, 20).
• For depth = 30 meters, number of bubbles = 10. Plot the point (30, 10).

Step 3: Plot the Points for Plant B

• For depth = 2 meters, number of bubbles = 21. Plot the point (2, 21).
• For depth = 5 meters, number of bubbles = 27. Plot the point (5, 27).
• For depth = 10 meters, number of bubbles = 40. Plot the point (10, 40).
• For depth = 16 meters, number of bubbles = 50. Plot the point (16, 50).
• For depth = 25 meters, number of bubbles = 34. Plot the point (25, 34).
• For depth = 30 meters, number of bubbles = 20. Plot the point (30, 20).

Step 4: Draw the Lines

• Connect the plotted points for Plant A with a line.
• Connect the plotted points for Plant B with a different - colored or dashed line (to distinguish between the two plants).

(Note: Since we can't draw the actual graph here, but the above steps describe how to construct the line graph using the given data. If you were to draw it on the grid, you would label the x - axis as "Depth (meters)" and the y - axis as "Number of Bubbles per minute", and then plot the points and draw the lines as described.)
