Ecology Mr. Willis

Question / Purpose  (Question that interests you or one that you are getting paid to answer)  How does ________________ affect the rate of seed germination?  (what will you use to fill in the blank? Soaking in coke, HCl acid, alcohol; sanding, cracking, etc)

Hypothesis  (General statement about what you have observed along with a prediction of what will happen next time)  (Use Occam’s Razor as a guide)  If I ____________________, the seed will germinate faster than if it were soaked in water

Materials: (what you will need) -6 Corn seeds -2 Paper Towels -2 ziplock bags - ? - ?

Procedures: (how you will test the hypothesis. Should have at least 2 groups and list as steps) Control Group: 1. Soak 3 seeds in water for 1 hour 2. Place seeds on a damp paper towel 3. Place paper towel & seeds in a ziplock bag and seal it shut 4. Check on seeds each day 5. If towel dries out, re-wet it 6. Record each day a seed germinates Experimental Group: 1. ? 2. Place seeds on a damp paper towel 3. Place paper towel & seeds in a ziplock bag and seal it shut 4. Check on seeds each day 5. If towel dries out, re-wet it 6. Record each day a seed germinates

After you develop your experiment, ask yourself the following question: Does my experiment really test my hypothesis?

Data  (Place to record all measurable data)  Data: Control Group Experimental Group Day 1 soaked in water 1 hour ? Day 2 no change ? Day 3

Results  (what happened?)  The seeds that were _______________ germinated _______ day(s) faster than the seeds that were _________________

Conclusions  (Was your hypothesis supported by the data? Opinions about why you got the results you did. What did you learn?)  My hypothesis (was/was not) supported by the data. The seeds that were ______________ germinated faster than the ______________ group. I think this happened because ________________

Sources of Error  (What could have affected the outcome of the experiment?)  Possible sources of error may have been:  ___________________

From this experiment, list the following:  Independent(Manipulated) Variable:  Dependent(Responding) Variable:  Control:  Constants:
