physical fieldwork

• Title/subject/topic


  Investigating downstream change on Glenderaterra Beck
• How this links with the GCSE specification


  There are rivers represented on the specification
• Fieldwork location
• Why the location was suitable

  It was close to our centre and we were able to get there in the time allowed for our fieldwork
• Justification for hypothesis in relation to geographical theory
• Risks associated with fieldwork and how they were minimised

  • Tripping
  • Falling in
  • Wear appropriate footwear
  • Weather
  • Hypothermia
  • Sun screen
  • Heat stroke
  • Layers
  • Drowning
  • death
  • Have people around
• Methods used to collect data

  1. Impeller method

  2. Floating method

  3. Measure width

  4. Measure depth at intervals
• Why the methods were appropriate

  They allowed us to investigate the hypothesis and provide accurate results
• Sampling strategies


  • Stratified sampling
  • Systematic sampling
• Distinction between primary and secondary data
• Data presentation techniques


  • Line graph
  • Bar graph
  • Cross sectional profile
• Why the data presentation techniques were appropriate

  Line graph gave overall perspective and allowed predictions

  Bar graph showed unexpected data and provided better scale

  Cross sectional profile showed how depth and width increased downstream
• Key findings from the data
• Were you able to answer your hypothesis?
• Conclusions drawn
• How this fits with geographical theory
• Evaluation of methods


  Impeller method was reliable, floating method was less reliable due to issues with currents and obstructions

  To improve, could have taken measurements in upper, middle and lower course to see full downstream change
