MARCH 22 - Write Up LD-50 Lab
DUE MONDAY MARCH 26
LC-50 Lab Grading Rubric (80 pts total)
THIS LAB MUST BE TYPED!
____1. Introduction (5 pts) — Objectives, why the experiment was conducted
____2. Hypothesis (5 pts) — What do you expect will happen? (Is there a threshold?)
____3. Materials (5 pts) — List all the supplies you used.
____4. Procedure (5 pts) — Describe the procedure you used with enough detail that someone could duplicate your work. (You don’t need to include the finer details of your dilution procedure.)
____5. Data Table (10 pts) — include all items listed on reverse side under General Procedure.
____6. Observations (10 pts) — Anything you notice that might be helpful to you in writing your results and discussion section. (Such as uniform dampness, clumps of roots, color, etc.)
____7. Graph (20 pts) — prepared in Excel. It needs to include 2 y-axes to illustrate the percent NOT germinated (on the 1st y) and the average radicle length (on the 2nd y) versus the salt solution strength. Remember that the independent variable — what you control — always goes on the x-axis. Also the graph will need a title, axis labels, and clearly labeled data sets. You will need to ADD the LC-50 point onto your graph manually (draw it on by hand) AND the threshold of toxicity (see below). NOTE: You MUST include the average class data set if your data doesn’t have greater than 50% mortality!
____8. Results/Discussion (10 pts) — Discuss, analyze your results. Were they what you expected? Any sources of error? If you used the class average data, you’ll need to discuss why.
____9. Conclusions/Analysis (10 pts) — What are the implications of your results (for instance for farmers, for winter de-icing crews…)? What are some possible areas for further study? Also please include answers to the following questions.
What is meant by the term threshold of toxicity? (On your graph of percent germination vs. solution strength, label the threshold of toxicity. Show this just above zero, if there isn’t one.)
- Different species have varying tolerances for different pollutants. If you were to study ecosystem health, what characteristics would you need to have in a good indicator species?

Presentation
You need to determine:
What happened and when?
What caused the event? Responsibility?
What were the important contaminants/people involved in the event?
What were the health/environmental consequences of the event?
What were the general consequences of the event, in terms of the reaction to it — media, legislation, outrage, company policy, etc.
You need 2-3 different sources for your info.
You may choose to format your information as a Google doc, PowerPoint, YouTube link, or document with photos/images.
Save your formatted project on a flash drive or email to cnoon@mcleanschool.org before class on Friday February 10.
