- 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
- Factors which we control
- Only one measure was taken for each temperature, meaning there could be anomalies in the results, can't determin the reliabilty of the results
