# data[].attributes.body
- decimal places of data must match the decimal places of the uncertainty values

Calculation
Show one sample calculation, the rest should be in the appendix table. Then the processed data should be tabulated.

# data[].attributes.body
- use scientific convention (include state symbols)

# data[].attributes.body
- Missing the word "molar enthalpy" in research question
- Explain the significance (application)
- Explain why combustion reactions are exothermic
- Calculate the theoretical value (show process)
- Equipment and chemical table should be separate
-

Methodology is not detailed enough

Photograph of equipment  is much better than diagrams from the internet

Risk Assessment
- Must keep information relevant

# data[].attributes.body
-Clear presentation with appropriate significant figures as well as good data tables

# data[].attributes.body
- link back and how it answers your RQ
- always justify a statement that you make e.g why? How?
- don’t forget to talk about further extensions of your investigation!

# data[].attributes.body
- Evaluated points relate to background and should answer your research question in a clear manner. Relevant chemistry highlighted in your data should back this up
- State the limitations of your experiment and realistically propose improvements that can be carried out in the lab.
- Consideration of sources of errors and how they affect data.
-Comparing secondary data to your primary data.
-Relevant and realistic extensions proposed.

# data[].attributes.body
- show qualitative observations as well
- only provide sample calculations (the rest goes in appendix)
- significant figures and decimal places
-

# data[].attributes.body
- Make sure to use conventional units e.g. cm3 not mL
- Label your figures
- Use proper mathematical notation

# data[].attributes.body
-Good mixture of qualitative and quantitative data. Qualitative should supplement the quantitative data
-Relevant data processing that will express information more explicitly, for use within the conclusion.
-All relevant uncertainty calculations for use within evaluation.

# data[].attributes.body
- use tables to better organise

# data[].attributes.body
Presentation of the data, evaluation should be in a table format, huge blocks of text makes communication less clear

# data[].attributes.body
- CONCISE and RELEVANT
- focused RQ and variables e.g concentrations etc.
- in your RQ should be able to identify important variables
- citation and sources
- IV, DV, CV need to be explained and justified
- need to show safety, ethical, or environmental considerations (relevant to your IA)

# data[].attributes.body
- Don't copy paste diagrams from the internet

# data[].attributes.body
Only mentions one evaluation point. Does not include any improvements

# data[].attributes.body
- Relevant chemical mechanisms and theories need to be mentioned
-Variables need to be addressed in an explicit manner with reasoning.
-emergency procedures need to be mentioned for all chemicals in the experiment.
-Concise methodology

# data[].attributes.body
- need to show more initiative and engagement e.g in method
- don’t say “I’ve always been interested in...”
- show more in the presentation and layout

# data[].attributes.body
Personal engagement should be expressed in a way that shows personal interest within the topic question and a certain level of curiosity and proactive engagement.
