After the long process of making and editing our questions we have finally moved on to our hypotheses! We had to make changes to the questions three times before writing our hypotheses. The questions and hypothesis are written below.
Question1: What do non-woody plants do in the winter? Do they die and turn brown or stay alive and stay green?
Hypothesis1: We think that many plants will be dead and brown, because non-woody plants don’t have as long as a life span as woody plants and don’t live as long in freezing temperatures.
Question 2: What soil contains more nutrients? Disturbed soil or non disturbed soil?
Hypothesis 2: We think that disturbed soil has less nutrients than non-disturbed soil when it gets moved. We think that some disturbed soil has more nutrients than non-disturbed soil, because things are added to it like compost, seaweed and miracle grow.
Question3: Are there different nutrient amounts in the soil in conifer-dominated, marshes, meadows, and deciduous thicket plant communities?
Hypothesis3: Yes, we do think that there are different nutrient amounts in conifer-dominated, marshes, meadows, and deciduous thickets, because of the diverse plants. The different plants that are in the distinct plant communities probably need different nutrient amounts concluding that there are different nutrient amounts in the various plant communities.

Hello 3rd to 5th graders!
ReplyDeleteThe hardest part is asking the right questions and creating testable hypotheses.
I am wondering if you are going to measure soil nutrients, and if so, how are you going to do that?
Keep up the good work!

We already are measuring the soil nutrients. We have a test kit that we use to test the nutrients. We test for PH, Nitrogen, Potassium, and Phosphorous. We have to add different ingredients for the different nutrients. Thanks for the comment, we love answering them.
