1 Trashket/Whiteboard Test Review 1.Which ecosystem has the most biodiversity? 2.Which ecosystem has the most sustainability? 3.What is the average number of organisms found in all three ecosystems together? We will review for our exam on how different environments support different variety of organisms and how biodiversity helps the sustainability of an ecosystem by using trashket. S Ecosystem B, it has the most plant and animal life. Ecosystem B, it has the most biodiversity. If you add all plant and animal species and divide by the number of ecosystems (3) you get an average of 57 organisms.

2 P - Things I need to Know 1.Different environments support different variety of organisms 2.Biodiversity helps the sustainability of an ecosystem 3.Effects of human activities on watersheds 4.Characteristics of objects in our solar system that allow life to exist 5.Microgravity 6.Calculate and contrast situations of work and no work 7.Illustrate geotropism 8.Diagram flow of energy (food chain, food web, and energy pyramid)

3 A/C - Trashket Rules: 1.One person shoots at a time from each group. 2.Must have the correct answer and make the basket first 3.When the music stops you must be seated and quiet to listen to an explanation.

4 A/C - Whiteboards Rules: 1.Use your whiteboard to answer 2.Music: Discuss answer with your group 3.When the music stops you show your answer (Voice 0) 4.Teams with correct answer get a point.

5 What is the formula to calculate work? W = F X D

6 How much work did Aaron do if he used 45 N of force to move a box 8 meters up a ramp? 45 N 8 meters W = 45 N x 8 m W = 360 J

7 Work or no work? NO WORK

9 What plant growth response is demonstrated by the picture below? GEOTROPISM

10 Draw how the roots will grow? What force causes the roots to grow that way? GRAVITY

11 (True or False): NASA can use this model to estimate distance between planets. TRUE

12 (True or False) The model below show the correct number of planets in our solar system. TRUE

13 List 3 characteristics of Earth that allow for life to exist? Presence of Water Proximity to the Sun Composition of Atmosphere

14 What are these astronauts experiencing? Microgravity

15 The following diagram shows pH level numbers of liquids, Which pH level number range is safe to for plants to absorb? A B C D

16 Which watershed has unsafe levels of pH, if normal water pH is 7? Watershed 1 Watershed 2

17 Which region has the most freshwater ecosystems based on the graph below? Salinity Temperature Region 1 Region 2 Region 3 Region 4 Salinity (ppt) & Temperature ( 0 F Average salinity & Temperature by region

18 Which region has the highest temperature? Salinity Temperature Region 1 Region 2 Region 3 Region 4 Salinity (ppt) & Temperature ( 0 F Average salinity & Temperature by region

19 Which body of water has the most under water plants based on oxygen levels? Oxygen Levels mg/L Ashville Elridge Canal Lake Tecumseh Lago Mar Blackgut Ashville Elridge Canal, more oxygen means more plants releasing oxygen.

20 A lake with an average temperature of -2 0 C and 100 cm annual precipitation is most likely part of which biome, based on the graph? TAIGA

21 A scientist is studying this watershed. Which of the following are abiotic factors he could study? Fish in the lake Aquatic plants Stream Flow Precipitation

22 What do the arrows represent in this food web? FLOW OF ENERGY

23 Identify the producer in this food web. PHYTOPLANKTON

24 Which organism has the least amount of available energy in the food web below? F. Polar Bear

25 According to the illustration and what you know about food webs, which organisms is the most crucial for the survival of this ecosystem? A. ICE ALGAE

26 The following food web is part of which biome? TUNDRA

27 How many trophic levels would an energy pyramid of this food web have? 5 Trophic Levels

28 Which organisms would be the least affected by the decrease in number of mice? SNAKE GRASSHOPPER OWL MOUSE MOLE RABBIT GRASSHOPPER RABBIT

29 Calculate work for both situations? Who is doing more work? Situation A Situation B F=65 N D=4 m F=130 N D=2 m Work is the same. Both do 260 J of work

30 Which Texas ecoregion would be most affected by a hurricane storm surge? Gulf Coast Prairies and Marshes

31 Name that biome Western hemlock

32 Name that biome Kangaroo Rat

33 Name that biome White-tailed deer

34 Name that biome Prairie dog

35 Name that biome Banana tree

36 Name that biome Lichen

37 E – Exit Ticket Things I know Things I need to know How I will prepare.

38 E – Exit Ticket Things I know Things I need to know How I will prepare. This could be you… if you don’t take the time to study tonight! Trashket is posted on the web site… please review!

39 All you need on your desk is something to write with! Let’s review! 1.Different environments support different variety of organisms 2.Biodiversity helps the sustainability of an ecosystem 3.Effects of human activities on watersheds 4.Characteristics of objects in our solar system that allow life to exist 5.Microgravity 6.Calculate and contrast situations of work and no work 7.Illustrate geotropism 8.Diagram flow of energy (food chain, food web, and energy pyramid)

40 TEST – Good luck! Stay calm, remember what we’ve learned … You’ll do great!

41 S- Match the description with the picture. 12/11/13 Succession Vocab Obj: Describe the role of ecological succession in a microhabitat. 1._______ The pond fills with vegetation; there are few areas of open water. The pond becomes a shallow marsh 2._____ over time, dead plant debris and sediments from the surrounding land slowly fill the pond as more vegetation grows 3. _____ a limited variety of plants and animals inhabit the newly created pond. 4. ______ a more diverse population of plants and animals inhabit the pond. A. B. C. D.

42 P- Read the paragraph below on the steps of ecological succession of a pond. The pond continues to fill with sediments and eventually forms a swamp. Over time, the swamp may dry and, through ecological succession, could become a forest or grassland depending on the biome. It may take several hundreds to thousands of years for the pond to be transformed into a forest or grassland. If Ecological succession is a gradual change to an ecosystem over time. How will it affect a microhabitat like a garden?

43 A: Copy the succession vocabulary from edusmart in your journals. C: Using your vocabulary describe how an ecosystem can change over time. E: Word wall. Write the vocabulary word and draw a picture on the front of your paper. Put the definition on the back.

44 Ecological Succession EDU S- record the name of the organism and the biome it would be found in. Western hemlock Prairie dog Kangaroo Rat Banana tree White-tailed deer Lichen

45 P- Read the TEK and define the vocabulary 10) Organisms and environments. The student knows that there is a relationship between organisms and the environment. The student is expected to: (C) observe, record, and describe the role of ecological succession such as in a microhabitat of a garden with weeds.

46 A- Complete the graphic organizer Ecological Succession- gradual change in an ecosystem Primary succession Starts with a ________________ Examples of Pioneer species are: _____________ Time frame: _________________ Ends with: __________ Secondary succession Can be influenced by : ________________ ________________ Starts with ________________ Time frame: ___________ Ends with: __________

47 C- Interactivity- record the steps in your journal E- Quiz- Number your paper 1- 10

48 Succession Reading S - Nelson collected worms from two different soils and then measured their mass instead of counting them. Which soil had the most worms according mass? We will describe the role of ecological succession by completing book work and a writing prompt. SOIL 1 SOIL 2 Soil 2 had the most worms because the mass was g and soil 1 had a mass of g.

49 P: Read pages Describe how ecosystems change? 2.Do they change in predictable patterns? 3.Do they change quickly? 4.Do they increase in stability over time? 5.How do ecosystems reach equilibrium? A C: Draw and label the process of primary succession AND Secondary Succession

50 E: Writing to learn Write a one page paper explaining how primary and secondary succession work? Make sure to give examples of each type of succession. USE pages for help.
