Title: to investigate how the river in cardingmill valley changes as it goes downstream
Hypothesis: the river will get deeper and wider as it goes downstream and the stones will get smaller and more rounded.
Reasons for location: easily accessible because it was national trust land, could investigate different parts of the river and see how it changed.
Risks: falling into river and hitting head on rock- wearing sensible shoes and avoiding walking over slippery rocks. accident in water- drowning - we did not go into fast moving or deep water. we only went into areas considered safe by our group leader.
Primary data technique:
1. selected 10 stones using a quadrat. we then measured them and described their shape using a scale from angular to rounded. - quadrat means we were not biased choosing the stones.
- we measured the width of the river in 3 different locations using a measuring tape. - so we can see if the river gets wider as our hypothesis states.
secondary data technique:
- we used photographs from the internet that showed the flood management techniques.- we were able to see a wider range of flood management techniques in different parts of the river as well as the parts we could access.
data presentation techniques:
1. we drew a cross section to show how deep and wide the river was in the 3 different sites. - we chose this because it showed both the river depth and river width in one graph.
2. we drew a rose diagram to show the shapes of the stones at the three different sites- very clear visual representation of the number of stones of different shapes. we could also overlay them which made the comparison between the three sites easier.
conclusion:
we found the river got wider as it went downstream. this was clearly shown as the upper course was 1 metre wide, in the middle course it was 1.5 metres wide and further downstream it was 2.5 metres wide. the stones also got smaller and more rounded as ww moved away from the upper course. the mean length was 10.5cm in the upper cause, and 6cm further downstream.
accuracy:
it was difficult to accurately measure the width of the river because it was difficult to use the tape measure and pull it tight enough. we could improve this by 2 people carrying out each reading to make sure the result is correct.
reliability: when we measured the depth of the water it was not as we expected because it had been very dry in the days before our visit so the channel had less water than usual. we could improve this by going back on a 2nd day to compare our results,
human enquiry
title: to investigate the impact of the redevelopment of brindley place in birmingham.
hypothesis: the land use will have changed from old industrial factories to a range of entertainment and offices. the redevelopment will have improved the environment of the area and made it more popular with visitors.
reasons for location: easily accessible because close to school, very good example of a redevelopment project where there had been lots of investment and changes to be studied.
risks:
1. getting run over: we chose a pedestrianised place to visit and when we stopped to carry out surveys we made sure we were on a very wide pavement
2. stranger danger: we stayed in groups of 3-4 at all times and always had a sight of where the teacher was and how to contact them if needed.
primary data technique :
1. carried out a pedestrian count in 10 different sites by counting all the people who walked past in 3 minutes- timed carefully to make sure it was 3 minutes so as accurate as possible.
2. we asked 10 people a questionnaire about their opinion of brindley place and how it had changed: we wanted to get the opinion of people who used brindley place ghe most and tried to get as big of a sample as possinle to make it more reliable
secondary data technique: we used google maps to vheck what fhe bhildings were being used for- we were able to take our time to plot the different land use and. ompare it to what we had found when we visited to make sure there wasnt any mistakes.
data presentation techniques:
1. we drew located bar charts to show the results of our pedestrian count: shows both the number of men and women and located them onto a map because this then showed us very clearly where the busiest parts of brindley place were.
2. we drew pie charts to show the questionnaire responses showing peoples opinion of brindley place: we chose a pie chart because it is very clear spand shows different proportions very well.
conclusion: we found that the landuse had changed a lot and there wasnt any now a large proportion of new offices such as HSBC and entertainment venues such as the sealife centre and zizis resturant. our pedestrian count and questionnaire showed us the area was getting more popular and busy, especially around the main square with the cafes and restaurants and people think it has been much improved. 72 percent rated the facilities as excelent.
accuracy: at times it was difficult to correctly plot the land use because we were not sure what the building was being hsed for wnd it was hard to find the buildings on the maps we were using we improved this by using google maps when we got nack to school.
reliability: we went on a cold day so not many people were there when we carried out our pedestrian counts. we may have got very different results on a different day, we could improve this by going on a more busier day such as a sunny weekend to compare results
