Plant four seeds in each pot. Plant each seed the same distance under the soil. Place all pots in an area so they can get approximately the same amount of light. Give the pots the following amount of water each day for 30 days. After 30 days, find the average height of the plants in each pot.
Plants grow higher if they are given more water .
The plants that were given most water grew tallest. However, if we had used more pots and given some plants more water, plant height may not have been higher. It may have been too much water for the plants. They may have died due to over watering. We can see that the line is leveling off in pots that had more than 16 ml of water.
