• Research questions, was clear and researchable. IV and DV are clear and are appropriate.

• Methods, materials and ethical considerations were present

Data Analysis: 5

• Appropriate use of tables and graph, clearly labelled and detailed

• Qualitative and quantitative data was used to support the research

Conclusion: 5

• Links back to research question

• Referring back to data. explicitly using some data to support the conclusion

Evaluation: 4

• Realistic improvements were identified to help combat the weaknesses of the experiment.

• more detail could have been provided

Research design – 6

• Research question outlined within a broad context.

• The identification of control variables and choice of method of their control is showed in very detailed table, ensuring experimental validity.

• Methods are detailed and reproducible.

Suggested improvement: The reason why the shoot was chose instead of the roots was provided, but maybe a discussion about how that might affect the validation of the results wouls strengthen the method section.

Data Analysis – 5 or 6??

• Excellent communication of the recording and processing of the data.

• Appropriate Statistical analysis were applied.

• Graph interpretation is clear with good explanations about tendencies and value ranges.

  
  

 Suggested improvement: Maybe a brief discussion about if possible outliers influenced the tendency could be added.

Conclusion – 6

• The conclusion is relevant to the research and consistent with  the analysis

• Comparison with published material reinforce their findings.

  
  

Evaluation – 6

• It is successful at explaining the impact of the weaknesses of the method and the suggested improvements are realistic, such as the use of a string along the shoot instead of just place the shoot against a ruler, and proof of deep reflection on their own work.

Could it be linked to literature more (make more interesting?)

Data analysis: 5 One graph seemed to have ? where there should have been values improve this

I wasn't particularly clear why some statistical tests where chosen - perhaps an explanation why this particular test was chosen could be helpful?

Conclusion: 4

Some relevant comparison + conclusion that is relevant with question but not fully consistent with tests

Evaluation: 4

sensible improvements suggested
