This document provides a lesson on volume including defining volume as the amount of space an object takes up. It gives conversions between units of volume like liters and gallons. Students are asked to complete statements with volume conversions and calculations using formulas. They are also asked questions about finding the volume of regular and irregular objects using tools like graduated cylinders.

Read the following experiment and then answer the questions below:
John wanted to see if the amount of salt water added to the soil affected the growth of the pea plants. He set up 4 pea plants each containing the same amount of potting soil in the same type of pot and placed them all in front of a large window. The 1st pot received no salt water, the 2nd pot received 10 mL of salter water, the 3rd pot received 20 mL of salt water, and the 4th pot got 30 mL of salt water. John measured the growth of each plant in centimeters every 2 days for the entire month of September. At the end of the month, John found the following averages of growth: 1st pot-16 cm, 2nd pot-13 cm, 3rd pot-9 cm, and the 4th pot-4 cm.
