Beetroot experiment

  • Beetroot Practical
    • Factors which we control
      • Diameter of the beetroot cylinders
      • Surface area of the beetroot cylinders
      • Temperature of the water baths
      • Length of time the beetroot cylinders spent in the water baths
    • Limitations of the experiment
      • Random errors due to the variations in how you conduct the experiment, e.g. slightly different diameters of beetroot discs or temperature of the water bath
      • Only one measure was taken for each temperature, meaning there could be anomalies in the results, can't determin the reliabilty of the results
      • insufficent number of intervals of the independant variable, every 2 degrees?
      • samples were taken from genetically varied beetroot plants, different concentrations of betalain
    • Improving the experiment
      • repeat the experiment 3-4 times and collect averages
      • Take more samples at each temperature and have more intermediate temperatures
  • Only one measure was taken for each temperature, meaning there could be anomalies in the results, can't determin the reliabilty of the results
