Agenda

1. Agenda: 9/11/12Biology1. Place bags on lab tables, take out Science Scenarios( except 6thpd) and wait for instructions so that you can be seated...2. Test 1***** ( only 6th pd) 3. Complete Science Scenarios ( for homework, due tomorrow), Do Bell Ringer #5…all bell work due today!4. Interactions within a Community Worksheet( Outline: Homework ( due to be completed by Friday!)***if you did not turn in bell work, then do so for a 70…tomorrow it’s a 50…after that its not accepted!!!!*****( only 6th period excluded)

2. Agenda 9/11/12Chemistry1. Place bags on lab tables, take out Science Scenarios and wait for instructions so that you can be seated...2. Test 13. Density Worksheet ***if you did not turn in bell work, then do so for a 70…tomorrow it’s a 50…after that its not accepted!!!!*****

3. 9-12-12 ( Biology) Place bags/purses to the side….be seated and lets start notes!!!! Review from yesterday: Symbiotic relationships are relationships ( or an ecological interaction) between two organisms. There are four types of symbiosis . • Commensalism is a symbiotic relationship in which one organism benefits and the other organism neither benefits nor is harmed. Mutualism is a symbiotic relationship in which both organisms benefit. Parasitism is a symbiotic relationship in which one organism benefits and the other organism is harmed. Predationis a symbiotic relationship in which one organism preys on (and eats) another organism. • Questions over yesterdays worksheet?????

4. Notes…continued Abiotic and Biotic Factors Abiotic factors: are essentially non-living components that effect the living organisms . Ex. Sunlight, temperature, water, humidity Biotic factors: a living thing, such as an animal or a plant, that influences or effects the ecosystem. Ex. Humans, sunflowers, bees, trees, dogs, ants

5. Journal Notes- Abiotic and Biotic Factor Cards In your journals, cut out the headings : Abiotic Factors /Biotic Factors. Create two columns using these headings. Next, cut out each factor and place them in the appropriate heading.

6. Tomorrow…BYOD Day! You will work in pairs on an Ecosystem Comparison Project. Bring your laptop, iPad, or cell phone device so that you can research!!!!

7. Chemistry- Agenda 9/12/12 • Review Density Worksheet • Complete and Turn Density Lab #2 ( write this up in your lab journals!) ****your lab report write should have these headings below. I have omitted the procedure, materials list, and discussion portion of the formal write up.**** Title Purpose ( the objective) Introduction ( background information) Data Table ( your measurements and calculations) Conclusion ( answer the two questions in complete sentences) ****your lab report write should have these headings below. I have omitted the procedure, materials list, and discussion portion of the formal write up.****

8. Biology- 9/13/12 Bell Ringer 6 Directions: Classify each of the following scenarios as either mutualism, commensalism, and parasitism. Explain why you chose each symbiotic relationship 1. Barnacles create home sites by attaching themselves to whales. 2. Ticks feed on deer blood to the deer’s detriment. 3. The stork uses its saw-like bill to cut up the dead animals it eats. As a result, the dead animals carcass is accessible to some bees for food and egg laying. 4. Ostriches and gazelles feed next to each other. They both watch for predators and alert each other to danger. Since the visual abilities of the two species are different, they each can identify threats the other animal would not as readily see. 5. Yucca flowers are pollinated by yucca moths. The moths lay their eggs in the flowers where the larvae hatch and eat some of the developing seeds. Both species benefit. 6. Hermit crabs live in shells made and then abandoned by snails. 7. A cuckoo may lay its eggs in a warbler’s nest. The cuckoo’s young will displace the warbler’s young and will be raised by the warbler.

9. Biology Cont….. Chose a partner. You are now about to start your research for your Ecosystem Comparison Project. Chose the Biomes/Ecosystems( two) that you want to compare. Start your research using your device. Follow along as I go over the guidelines. **Carrying Capacity: The carrying capacity of a biological species in an environment is the maximum population size of the species that the environment can sustain indefinitely, given the food, habitat, water and other necessities available in the environment **Limiting Factors: a factor that controls a population's growth, such as organism growth or species population, size, or distribution. Limiting factors includes space, water, and food. ( you should have these on your ecosystems outline already) You will have today, very little time tomorrow ( test corrections), and then Monday, to complete your project and set up your posters.

10. Biology- 9/14/12 • Turn in Outlines ( YOUR HOMEWORK) ( 2 min)- IF IT IS NOT READY, ITS ALREADY LATE!!! • Test Corrections: ( Listen to your teacher or read below for instructions)- 3 min instructions/ 25 min for corrections * Must correct EVERY question wrong on a separate sheet of paper. With your peers, work on a noise level of one to discuss/review each test question. You must chose the question you think is best and provide an explanation as to why you chose your new answer. If you already have the correct answer mark, you must still provide an explanation. Be prepared to explain your answer choice out loud. ANY person who remains off task after being re-directed once, forfeits their right for test corrections. • Review Answers (15 min) • Use the extra time ( if there is any) to either work on: • Ecosystems comparison projects • Missing work from this week: science scenarios, symbiotic worksheet, or outlines RETEST IS ON MONDAY…STUDY THE WEEKEND AWAY!!!!
