Project Information
Many students think of the scientific method as a step-by-step process that all scientists follow in order. But real research is rarely so neat and tidy…it is really more of a research cycle or spiral because things you learn in one step can change your ideas about what you’ve already done or about next steps.
It is OK to change your thinking! We encourage you to go back and edit things you write in this section at any time as your ideas change. Just remember to explain your changes in your updates feed.

Research Question | How does water percentage effect growth of soybeans? |
Predictions | If the water conditions are ideal(75%-80%), the soybean growth will proceed at optimal rate. If exposed to standing water (100%+), then growth rate will be stunted. If enduring less then 25% water, growth rate will decrease. |
Experimental Design | Our group germinated three separate trials of three seeds in groupings of three pots each and only two trials ended up germinating. Once germinated, we proceeded to expand the time between watering to one of the groups to 25 mL every seven days. Another group we kept as control group, which we watered every other day 50-75 mL. Our last group we exposed to flooding conditions by watering excessively so standing water was present. Once we implemented these environments, we take measurements in centimeters everyday to quanitatively collect data. |
Conclusion | In the end our flood trial had the biggest and boldest leaves as well as grew to be the tallest and had the best overall growth rate. Our drought trial slowly stopped absorbing water and towards the end started dying from the top down showing that water was no longer being transported throughout the entire plant and lack of nutrients in the area with lack of water died off. |
