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.

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.
