12.09.13 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.

P - Things I need to Know 1. Different environments support different variety of

organisms2. Biodiversity helps the sustainability of an ecosystem3. Effects of human activities on watersheds4. Characteristics of objects in our solar system that allow

life to exist5. Microgravity6. Calculate and contrast situations of work and no work7. Illustrate geotropism 8. Diagram flow of energy (food chain, food web, and

energy pyramid)

A/C - Trashket Rules: 1. One person shoots at a time

from each group. 2. Must have the correct answer

and make the basket first3. When the music stops you

must be seated and quiet to listen to an explanation.

A/C - WhiteboardsRules: 1. Use your whiteboard to answer2. Music: Discuss answer with your

group3. When the music stops you show

your answer (Voice 0)4. Teams with correct answer get a

point.

What is the formula to calculate work?

W = F X D

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

Work or no work? NO WORK

What is the advantage of using a ramp? LESS FORCE

TEST – Good luck!

Stay calm, remember what we’ve learned … You’ll do great!

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 marsh2._____ over time, dead plant debris and sediments from the surrounding land slowly fill the pond as more vegetation grows3. _____ 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.

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?

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.

12.12.13 Ecological Succession EDUS- 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

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.

A- Complete the graphic organizer

12.13.13 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 334.5 g and soil 1 had a mass of 286.7 g.

P: Read pages 376-3791. 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

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 377-378 for help.
