Lab conclusion

5. Review Define ECOLOGY: An organisms interaction with its environment
Define ECOSYSTEM:
The living and the non living interacting with one another
Living= biotic
Plants, humans, bacteria, animals, trees, flowers
Non living= abiotic
Rocks, soil, water, sun, oxygen, nitrogen, CO2, dirt, mud

6. Review The 4 properties of populations: 1. Size 2. Density
The number in the population
2. Density
How many in an area
3. Dispersion
How populations space themselves in an area
4. Age diagrams
How many are a certain age

7. Dispersion

8. Growth models Exponential Logistical Nickname: J-Curve
Unregulated growth and unlimited resources
Sustainable?
Nickname:
S-Curve
Effected by limited resources
Population Stabilize

9. Age Diagrams
The different colored bars will represent different age groups and the length of the bars represent the amount of people in that age groups.

10. Review Do all organisms have an equal chance of surviving? NO!
Survivorship curves!

11. Survivorship Curves Type I: Type II: Type III:
High survival rate in young
Effective parenting
Overall low death rates
Type II:
Constant death rate
Limited parenting
Type III:
High death rate in young
No parenting
A lot of offspring because so many die
Once survive till a certain age, high survival rate

12. Match the curves to the populations
Type I
Type 2
Type 3

13. Carrying Capacity Limiting factors affect the carrying capacity
1. Water
2. Food
3. Shelter/space
4. Competition
Food, water, space, competition

14. A more realistic image
If I only showed you the exposed graph, most of you would say this is exponential growth. So far, you are correct. In the beginning, we see early rapid growth. Click box. Eventually the population growth will start to slow down as resources become limited. The population growth will stabilize. Now this looks like a logistical curve.

15. Graph’s predict birth and death rates
When the population is below its carrying capacity, there is room to grow so this is point B. When the population is above its CC, the population will decrease, point D. The population wants to be at its carrying capacity.

16. Lab What are we doing today??
Students will be able to collect and graph data, recognize models and their limits, and design their own model for an original experiment.
Objective: The student is able to make models and make scientific claims and or predictions about the effects of variation within populations on survival and fitness.

17. Title: Oh Deer Lab
Materials:
People
Pen/pencil
Data table
Graph paper

18. Procedure: Every student will play a deer or a resource.
The resources will be food, water, and shelter. They will act out the hand signals during the game.
The deer will also have a particular resource they are looking for. They will run from one side of the field to the resources BEFORE other deer reach their resource.
If you do not reach your resource, you are dead

19. Data Collection
Mrs. Ireland will collect the data in a data table then she will share the data with you following the lab.
We will then make a line graph of this information!

20. Data Collection # or rounds Deer at the beginning Deer at the end 1 23 4 5 6 7 8

21. Data Analysis 1. What trends do you notice in your graph?
Answer the following questions on page 31 in your notebook.
1. What trends do you notice in your graph?
2. It’s important to keep in mind that this is a model and models have limits. With respect to the natural world, what is this model really good at representing? What does this model fail to take into account?
3. What is one way you could alter this model to better represent a specific condition or event?
4. What in the game represented carrying capacity?
