Scribe - Bridget S.
Agenda for Today
• Finished Lab 1- Microscope
• Talked about “Ecology of an Oil Spill” writing assignment- DUE 9/22/10
• Started ecology notes Ch. 18
The Microscope Lab Summary
• This lab was to help you get used to using a microscope.
• First, we put a small letter “e” clipped from a newspaper onto a slide, dropped a drop of water onto it, and placed the cover slip on top. (this is called a wet mount.)
• Then, we looked at the “e” from the microscope, adjusting the coarse focus knob until it came into focus. (your field of view.)
• We examined what happened when the slide was moved to the left and when it was moved to the right.
• We also examined the “e” under different powers and recorded what it looked like.
• Then, we prepared a wet mount with 2 pieces of crossing hair and examined them under different powers.
**Why did we do this lab? - to understand 1. field of view, 2. depth and resolving power, 3. how to increase magnification without losing your object, 4. familiarize yourself with how to use the microscope

“Ecology of an Oil Spill” Assignment- DUE 9/22/10
• Please read pgs. 5-7. (UP)
o You have been hired by BP to write a paper suggesting 3 ideas (and their approximate cost for each) for solving the oil spill problem and to help save the lives of marine organisms. (plants and animals)
o You need to research the effects an oil spill has on plants and animals first.
o Your paper should include the following;
A cover sheet
• Here are some additional things we went over in class:
“Wikipedia “ is NOT a source
Use in-text citations (Author, pg. #) after every sentence that is not yours
Do not use contractions
Be sure to write in 3rd person, no “I”
If you use the websites on pg. 6, still cite them correctly
Use the MLA FORMAT TO CITE
You may use the article on pg. 8A to get you started
Ch. 18 Notes so far
• Population is increasing rapidly, so we have to be careful to not lose all of the resources that we have.
• We learned new terms about ecology like;
Ecology- interactions between organisms and their environment
Abiotic factors- non- living chemical and physical factors
Biotic factors- living factors
Population- group of individuals of the same species living in a particular area
Community- all the organisms inhabiting a particular area
Ecosystem – the community and abiotic factors
Biosphere- sum of earth’s ecosystems
Environmentalism – started in the 1960s when people realized that unsafe technology was being practiced in the 1950s
• Start oil spill research
• Read textbook Ch. 18 and do notes (in Moodle)
• Finish Lab #1
• Termite Lab report due 9/10
