nature breaks it down
- The matter in nature's waste is broken down by various scavengers and decomposers.
- Sequence the process of decomposition by arranging illustrations showing the progressive decomposition of organisms.
- Use data to evaluate claims about how organisms decompose after death.
- Describe what happens to the matter in dead organisms when they decompose.
- What evidence do you have that things are changing?
- What is the cause of these changes?
- What is the effect of these changes?
- What is the term for this process?
- When do organisms or organic remains decompose?
- Why do things decompose?
- Do things disappear completely when they decompose?
- What happens to the matter in organic remains when they decompose?
- Is it possible to prevent something from decomposing?
- Wht affects how quickly something decomposes?
- With your partner, follow the directions on Tree Decomposition sheet
- With your partner, follow the directions on the Bison Decomposition sheet
- Find another group that has completed the activity and compare answers with them.
- Discuss any differences in opinion and come to an agreement
- Glue the illustrations, in sequence, into the second page of the worksheet.
- Open your Ecosystem's GoogleDoc
- Scroll to the bottom on the document and his enter twice
- Type: "Lesson 8-Nature Breaks it Down"
- Hit enter twice
- Discuss the following questions with your partner and answer them in your own words.
- How did the tree change during each stage?
- What might have caused the changes to the matter in the tree?
- How did the matter in the bison change during each stage?
- What might have caused the changes to the matter in the bison?
- What claim are you making about the matter in the tree and the bison?
- What data might serve as evidence for that claim?
- What is the effect of the decomposition?
- If the matter in each organism continues to decompose, will it disappear? Why or why not?
- Where do you think the matter moved as each organism decomposed?
- How long do you think it will take the matter to decompose completely?
