You will be investigating how different environmental conditions affect the germination of a seed. With only the materials provided on the list, for each question develop a hypothesis and an experimental design to test your hypothesis. You will then set up your experiments and take data over a week long period.
bean seeds (soaked overnight), paper towels , water,
baggies (for storage of seeds, window with sunlight,
drawer (dark), ziploc baggies, weak acid solution, refrigerator
Questons: (Choose 2 of the questions to investigate)
How Does Acid Affect the Germination of a
How is the Germination of a Seed Affected by Air?
How is the Germination of a Seed Affected by Sunlight?
How is the Germination of a Seed affected by Flooding?
How is the Germination of a Seed affected by Temperature?
On a separate page, write your report that answers the questions. Your report should include:
1. The Question
2. The Hypothesis
3. The Experimental design (how you set it up)
5. Data table(s)
|Lab Report Rubric||Excellent 3 pts||Good - 2 pts||Needs Work - 1 pt|
|Question/Hypothesis||written as a complete sentence, question is restated as a prediction that can be tested||Unclear phrasing, does include at least one question and answer||question is not answered, hypothesis not stated in a way that can be tested|
|Design||the procedure will accurately test the hypothesis, can be followed easily, materials listed or described||procedure does test the hypothesis, parts are unclear or may not fully test, some materials are listed||procedure likely will not test the hypothesis as stated, procedure unclear, materials not listed|
|Data||Clearly shows the all results of the experiment and includes a time frame, descriptors and any quantitative data taken, well organized,||Shows some results with some time frame and descriptors, organization lacking or hard to follow||results missing, hard to follow, only addresses part of the experiment, lack of organization|
|Conclusions||Summarizes the essential data used to draw conclusions; conclusions follow data (not wild guesses or leaps of logic), the experimental question is answered||Summarizes data, answers some of the experimental questions, includes a reference to the data||Does not answer question or summarize data|
