Samantha wanted to find out which soil types would best suit her herb garden. She set up 3 containers. Container 1 had loam soil, container 2 had black clay soil, and container 3 had a sandy soil. She added 5 parsley seeds, 5 basil seeds, and 5 thyme seeds to each container. She added 20 mL of water to each container every day and regulated the light to 12 hours light and 12 hours darkness. At the end of a 30 day period she analyzed her results.

Gloria set up three experiments to test which factor has the greatest effect on plant growth. In the first experiment she took 3 pots, filled them with a similar soil type and planted 5 carrot seeds in each pot. When the seeds germinated and grew to a height of 3 cm, she placed each plant pot into a light of varying duration. Group A had 12 h of sunlight, group B had 16 h of sunlight, and group C had 24 h of sunlight. At the end of 1 week she recorded the plant growth.
In the second experiment Gloria took 3 new pots and added different types of soil. In the first pot she added a loam soil, in the second she added a clay soil, and to the third she added a sandy soil. She planted 5 carrot seeds into each pot. Once the plants reached a height of 3 cm she observed the plants for an additional week and recorded plant growth.
In the third experiment Gloria used 3 more pots and placed 5 seeds into the soil of each pot. The soil was the same in each pot. When the plants reached a height of 3 cm she altered the amount of water each pot received. Group A received 10 mL of water every day, group B received 20 mL of water every day, and group C received 30 mL of water every day. She observed and recorded plant growth at the end of 1 week.
