Instructions: You will write a 1-page lab report using the scientific method to answer the following questions:

• Why do you see increases and decreases in the invasive species population?
• What are the implications associated with these alterations to the ecosystem as a whole?
  

When your lab report is complete - submit it in the classroom.

Part I: Using the lab animation, fill in the data table below to help you generate your hypothesis, outcomes, and analysis.

Years	Zebra and Quagga Mussel (density/m2)	Phytoplankton (µg/ml)	Zooplankton (µg/ml)	Cladophora Biomass (g/m2)	Foraging Fish (kilotons)	Lake Trout (kilotons)

4	1,000	2.5	1	100	100	10
7	2,500	2	0.5	200	80	8
10	7,500	1.5	0.25	600	50	5

16	7,500	1.5	0.2	243	40	4
20	5,000	1.75	0.4	136	60	6

Part II: Write a 1-page lab report using the following scientific method sections:

• Purpose
  • State the purpose of the lab.
• Introduction
  • This is an investigation of what is currently known about the question being asked. Use background information from credible references to write a short summary about concepts in the lab. List and cite references in APA style.
• Hypothesis/Predicted Outcome
  • A hypothesis is an educated guess. Based on what you have learned and written about in the Introduction, state what you expect to be the results of the lab procedures.
• Methods
  • Summarize the procedures that you used in the lab. The Methods section should also state clearly how data (numbers) were collected during the lab; this will be reported in the Results/Outcome section.
• Results/Outcome
  • Provide here any results or data that were generated while doing the lab procedure.
• Discussion/Analysis
  • In this section, state clearly whether you obtained the expected results.  Also discuss the results and what you learned from this lab.
