|Investigative Question or Issue: How do invasive plant species such as Eurasian Milfoil affect lake water quality with respect to pH, oxygen level, and N and P levels?|
While this challenge was written about Lake Luzerne, it could be modified and used with any Adirondack body of water.
With the help of your teacher, arrange yourselves into well balanced teams of three. This challenge will be organized into three parts. Each part will have at least one Product Quality Checklist (PQC).
Part I: Background Information
We have discussed the terms biodiversity and invasive species together and also applied these terms specifically to Lake Luzerne and the concern with Milfoil proliferation. Now, your group has the responsibility of becoming experts on Eurasian Milfoil. Using the resources provided, each of you will collect information to answer specific questions. Then, you will use one class period to teach each other the information. During a second class period, I will verbally test individual group members any aspect of the information studied. Each of you will receive an individual test grade on Part I (see PQC Part I.) The questions you must research are organized below:
Part II: Experimenting with Eurasian Milfoil (this part may have to be adjusted based on the ability to grow milfoil in the classroom)
Based on the information you have learned about Eurasian Milfoil, as a group, develop a hypothesis relating the presence of Milfoil to lake levels of oxygen, pH, nitrogen and phosporous. You will then be measuring these levels using scientific instrumentation in a mock lake setting created in our lab.
This data will be collected 2 times a week for three weeks. Each individual is responsible for their own lab write-up in their laboratory notebook. (This lab will count as three credits.)
Part III: Public Education is the Key! Your last piece of the challenge is to develop an educational message about Eurasian Milfoil in Lake Luzerne. Your message must include the following information:
(Ideas: video commercial, radio announcement, signage, pamphlets, other creative ideas)
Project supported in part by the New York State Museum Biodiversity Research Institute
Part I: Each student must earn a grade of 70 or above on the verbal test in orderto continue to Part II. Any student earning a grade below 70 will be retested independently at a designated time after school.
Part III: The public education piece must:
