Activity 31 Resistance to Erosion Lab –LAB
November 1
Daily Objective:
Today we will do the background research on our erosion lab report.
Daily Question:
Where do you think each soil belonged? (Hill, Cliff, or Marsh)

4. Background Research Paragraph describing 3 things not commonly known about your topic (erosion – specifically how different materials are affected by erosion)
Topic sentence states your topic
3 facts or pieces of information about your topic
3 explanations about those pieces of information
Conclusion restates what your paragraph was about

5. Act 31: Resistance to Erosion Data Table Basin
Observations
Erosion Ranking
Water Runoff Ranking A B C

6. Hill shape is maintained. Water flows off hill. Can see rocks
Afterwards, briefly discuss how your group ranked each basin.
Act 31: Resistance to Erosion Data Table
Basin
Observations
Erosion Ranking
Water Runoff Ranking A
Cliff
Hill shape is maintained. Water flows off hill. Can see rocks 3 1 B
Hill
Hill shape is not maintained. Water mixes with earth material to create flat shape. Some water flow C
Marsh
Hill Shape is maintained more than B but less than A. Water does not flow off but is absorbed. Can see some organic matter in soil. 2
First, discuss the results from each of these basins.

7. Data Tables and Graphs Label IV Label DV IV goes here # goes here
Unit of measure
IV goes here
# goes here
Six things that all graphs should have:
Title
DV label in words on the vertical axis (unit of measure)
DV labeled in evenly numbered increments
IV label in words on the horizontal axis (unit of measure)
IV labeled in even increments
Data displayed correctly
Optional – key to graph

8. Scientific Drawing
Make a drawing of your experimental setup and label all the materials used. Include a title and labels of all objects on straight lines to the right on the paper.

Test tube
Florence flask
Vinegar

9. Double Bar Graph
Double Bar Graph: a graph using parallel bars of varying lengths to compare data.
Erosional Run off for the Hill, Cliff and Marsh in Boomtown
Amount of erosion/run off
Type of Soil

10. Data analysis write a paragraph describing the relationship between the 2 variables
Your topic sentence re-states the two variables and states the relationship between them.
Your yellow sentences state the results from the 3 tests.
Your pink sentences go into further detail describing what the data in the data tables means in words from ALL 3 tests (also include how this data supports whether we should build houses on this material or not).
You formally conclude the relationship between the two variables by stating which one was the most resistant to erosion.

11. What should your data analysis look like?
Topic Sentence: In this experiment, we investigated the relationship of (your variables)
Body: Explain the results from all three basins:
Yellow: states what you tested & the results
Pink: What does a 3,2,1 mean & what it means in terms of stability and where you should build.
Concluding Sentence: As you can see, in this experiment we investigated the relationship of (your variables) and our results show____.

12. EXAMPLE:
In this experiment I tested the relationship between the amount of erosion/run off based on the 3 types of soil.
First, I tested soil A which I ranked a 3 for erosion and a 2 for run off. This means that Soil A is not very stable and that it could flood so the data suggests that we should not build houses on the Hill that contained soil A.

13. Conclusion - Summary paragraph describing all of the steps of the experiment and what you have learned/concluded.
Your topic sentence describes what the experiment was.
The body of your paragraph states/answers the following information in complete sentences:
Restate your hypothesis (yellow)
Was your hypothesis correct? Why/why not? (pink)
Summarize what the tests were & how you performed each test. 1 set of (Yellow & pink)
What were the results for each test? (summarize data analysis). 1 set of (Yellow & pink )
What was your purpose/problem statement? (yellow)
What have you learned about your purpose? (pink)
What were possible sources of errors in this experiment? (yellow)
In the future how could you learn from those errors? (pink)
You formally conclude which material is the most resistant to erosion.
Your paragraph includes transition words.

14. Future Research describe a new related experiment that would be interesting to do next. (Something related to weathering, erosion and/or deposition)
Topic sentence states what your new experiment might be
1 fact or detail about what the new experiment is
1 explanation about that experiment
Conclusion restates what your paragraph was about

When you finish, submit your assignment to the X drive. (DUE Friday!)
