| Explore | Our summers consist of working in the fields, working with different types of plants. Recently we took a field trip to a greenhouse nursery and to a testing soil facility, in which we learned that each plant consists of characteristics that enable a plant to survive. We have learned that certain plants are grown in different weather/seasons, soils can contain different nutrients, plants get their color through chlorophyll, and plants go through a process called photosynthesis. To answer your question on as to why maybe some plants are able to survive in such harsh temperatures we believe that each plant has some sort of system within them that prevents them from dying. Living in the central valley where all of our weather consists of skyrocketing warm temperatures we know that each plant has characteristics that allow them to survive in such hot temperatures, so with that said we would infer that plants living in such areas would have an anti-freeze system that will allow them to survive under those conditions. |

| Research Question | Which type of worm will give the most nutrients to the MHS ground soil to grow radishes? |
| Predictions | We hypothesize that the earthworm will help produce the most nutrients and show better results, therefore earthworms will be the most effective to areas with low soil nutrients. |
| Experimental Design | Our plan as a group is to create an experiment that will give us the most knowledge to help agronomy feed the world. Our procedure is the following: Gather 8- 1 gallon containers Make sure each container is well cleaned and dried Grab 1 gallon container and label each container with the type of worm Repeat procedure 3 until each container is labeled Fill 1 gallon container sized pot with MHS ground soil about ¾ of the container Repeat procedure 5 until each container is filled with ground soil Place 3 worms of each type to their corresponding container Repeat procedure 7 until each container has worms Create 3 holes 8 cm deep each 4 cm apart forming a triangle Repeat procedure 9 for each container Gather 25 raphanus sativus (brassicaceae) rashish seeds and put one seed in each hole Repeat procedure 11 for each 1 gallon container until each container has 3 radish seeds in each hole We will water every Monday & Friday We will measure every Friday Variable Testing: The variable that we will be testing will be the type of worm. Measuring Variable: How much nutrients each worm will give to grow radishes. Constant Variable: Same ground soil. Record Data: We will keep a journal and everyday record our observations and take pictures throughout the process. |
