1. Environmental Science Do Now 9-29-17
Do Now: Take your Do Now sheet out and complete.
Explain how an organism becomes resistant.
Name any three pieces of evidence that supports the theory of evolution by natural selection.
Explain how humans have used artificial selection in beneficial ways.
Explain how a human hand, a bat’s wing and a whale’s fin are homologous structures.

2. Environmental Science Do Now 9-29-17 KEY
There is variation within the population of organisms. Most of the organisms are susceptible to the pesticide and die; however, not all of the organisms die. Some have a mutated gene that allows them to survive exposure to the pesticide. These resistant organisms survive and can pass their resistant gene to their offspring.
Three pieces of evidence that support the theory of evolution by natural selection are: fossils records, anatomical records, and molecular records.
Humans have used artificial selection in beneficial ways, such as, breeding desired livestock and pets, and growing crops to feed their families (agriculture).
A human hand, a bat’s wing and a whale’s fin are homologous structures because they all have the same bone structures (wrist bones, upper and lower arm bones, etc.). However, they do not have the same function(s).

3. Reminders of Important Dates
1st Quarter Progress report grades close on Wednesday, October 4, 2017.
If you are failing a class, you have 5 more days to improve your grade before progress report grades are finalized!
When the school’s shipment of copier toner arrives, I can print a hard copy of your grade report for you.

4. Homework Species Interaction P.O.G.I.L., if unfinished.
Take the data you should have collected throughout the week to write up your seed germination lab report. Due on Monday, October 2, 2017!!!
Check out my page to get the details about the sections your lab report must have.

5. Objective
Students will know the types of species interactions within an ecosystem by taking notes, completing a worksheet on species interactions (P.O.G.I.L.), reading an article and answering exit ticket questions.
Mastery: 70% or better on the species interactions worksheet (P.O.G.I.L.)
70 pts. or better on close read

6. Engage - What type of interaction does this image display between the lionesses and the wildebeest?

7. Explore – Species Interaction Close Read
Students will read the article on Relationships between Organisms and will annotate the article. Each symbol is worth 2.5 points and each noteworthy comment is worth 5 points.
The goal is for each student to have 70 points worth of annotations and comments from the article.

10. The Niche What is a niche?
A niche is the range of physical and biological conditions in which a species lives and the way the species obtains what it needs to survive and reproduce.

11. Organism’s Ecological Niche
In ecology, a niche is a term describing the relational position of a species or population in its ecosystem to each other

12. Species Interactions Symbiosis Predation (Predator-Prey) Competition
Commensalism
Parasitism
Mutualism

13. Symbiotic Relationships

14. Symbiosis
The term symbiosis (from the Greek: syn "with"; and biosis "living") commonly describes close and often long-term interactions between different biological species.
The symbiotic relationship may be categorized as being mutualistic, parasitic, or commensal in nature.[

15. Predator-Prey Relationships
An interaction in which one animal (the predator) captures and feeds on another animal (the prey) is called predation.
Predators can affect the size of prey populations in a community and determine the places prey can live and feed.
Birds of prey, for example, can play an important role in regulating the population sizes of mice, voles, and other small mammals.

16. Predation
In ecology, predation describes a biological interaction where a predator (an organism that is hunting) feeds on its prey, the organism that is attacked

17. Competition
In a forest, for example, plant roots compete for resources such as water and nutrients in the soil.
Animals compete for resources such as food, mates, and places to live and raise their young.
Competition can occur both between members of the same species (known as intraspecific competition) and between members of different species (known as interspecific competition).

18. Commensalism
In ecology, commensalism is a class of relationship between two organisms where one benefits and the other is not significantly harmed or benefited.

19. Parasitism
Parasitism is a type of symbiotic relationship between two different organisms where one organism, the parasite, takes from the host, sometimes for a prolonged time.

20. Tsetse Fly: Spreads Sleeping Sickness

21. Man with Sleeping Sickness

22. Trypanosomes in the Blood

23. Mutualism
Mutualism is a biological interaction between two organisms, where each individual derives a fitness benefit, for example increased survivorship.

24. Extend – species interaction p.o.g.i.l.

25. Evaluate – exit ticket question compare and contrast the five types of species interaction we discussed today.
