Evaluation

Question 1

What are problems with data collection methods in your fieldwork

Answer 1

When measuring river width in the earlier sites some pupils did not pull the tape tight enough so it was not straight so the result is not an exact measurement

Some people started measuring from bank to bank rather than the edge of water at each side

Question 2

What are the limitations of data

Answer 2

In terms of sediment size everyone may not have rounded up to the nearest cm correctly and some recorded in mm. Some may not have been measured the longest side due to lack of concentration. When using the powers index scoring system there’s an element of subjectivity

Question 3

What other data may have been useful

Answer 3

Geology refers to the certain rock type of an area and certain rock types erode more easily than others. A geological survey map could have been used as it would allow us to see the sites we visited. We could categorise our samples by rock type during primary data collection to consider the effect of erosion

Question 4

How do you evaluate a conclusion

Answer 4

A conclusion comes towards the end of a geographical enquiry but it can often lead to further questions being asked such as whether the conclusion is reliable or not

Question 5

Explain how you could extend your geographical enquiry

Answer 5

We could’ve collected data at additional sites/stops which would have given us a more detailed picture of how the variables change downstream

We could’ve compared our results to data for the Shimna River with another river in a different location eg Whitewater River in Greencastle

We could’ve compared our data to a different time of year eg Summer
