Due Date: March 21st, 2014 Schlansky 2013-2014 Title: Bottle Ecosystems I. Introduction Write one paragraph that answers the following questions: What did we do? (briefly explain, don’t list all procedures) What is a bottle biosphere? What is a closed ecological system? WHY did we do this lab? (What did we want to learn about ecosystems?) II. Hypothesis List your two hypotheses – do not say if they were correct here! 1. What will your ecosystem be like after 3 weeks? 2. Will you be successful at maintaining a closed ecological system? Why or why not? III. Materials List all materials used in this lab. IV. Procedures Use bullet points/a list to explain exactly what we did (write it in the past tense) Include diagrams/pictures of steps V. Data/Results Observation Chart Include your observation chart. Include any additions notes VI. Analysis Discussion Questions Use the following questions to guide your response. Which organisms were successful? Which organisms were not successful? Why? What abiotic factors contributed to the survival of the biotic factors? What abiotic factors contributed to the death of the biotic factors? Why did we need at least one plant in the ecosystem? What ecological role do the worms play? Why is this process important? Why did we not need to add water after the bottle was closed? Explain how carbon was cycled in your ecosystem. Explain how energy was transferred in your ecosystem. Hypothesize what might happen if we left the bottles closed for another two weeks. If you were to do this experiment again, what would you change about the design of your bottle? Why? Diagrams Use diagrams to highlight points of your analysis and discussion questions Chart of Biotic/Abiotic Factors Food Web of Organisms Cycle Diagram of the Water Cycle VII. Conclusion Included Brief summary describing the investigation (what was done and why) How is the Earth a closed ecological system like our soda bottles? Summarize your results – GIVE DETAILS Were your hypotheses correct? Why or why not? Discuss any error that may have affected the results (there is always error) Meaning Do you think you were successful? Why or why not? What ecological cycles were necessary for your biosphere to survive? What did you learn about real ecosystems? Next Steps If you were to do this again, how would you change your bottle design? How do humans impact ecological cycles? What recommendations do you have for further research? FOR YOUR FINAL DRAFT: Make sure you have corrected all spelling and grammar errors – have someone proofread it for you. Make sure you have used all science vocabulary correctly. TYPE your lab report in Arial or Times New Roman, 12 point font. Double Space. ***When you turn in your lab report, staple your RUBRIC face up, on the right hand side, ON TOP of your lab report. This covers your name up while I grade and it SAVES PAPER!!!
