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


 Please answer questions on page 34. (UP)

“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
 Intro paragraph
 Body
 Conclusion
 Bibliography

• 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

Pgs. 1-2

• 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

Homework

• Start oil spill research
• Read textbook Ch. 18 and do notes (in Moodle)
• Finish Lab #1
• Termite Lab report due 9/10
