Research & Report Findings
Carry out research and report findings of how to best carry out a practical measuring production of a gas. You will need to bring your report and practical method to your Core Practical 1 Laboratory session so that you can follow it.
1. Carry out & report suitable research into the techniques you could use. Include neat pencil drawn diagrams.
2. Write a comparison of the techniques including an evaluation of accuracy of results expected from each technique.
Things to consider CPAC 5a
Things to consider CPAC 5a
CPAC 5a - Uses appropriate software and/or tools to process data, carry out research and report findings.
Carry out suitable research to support your planning into how to measure the rate of gas production
Write up a method in your own words specifying how to achieve accurate results by collecting quantitative data
Use research to support choices of equipment and planning by citing in the text
3. Updated the provided practical method by making improvements based on your research - so that the technique described will provide the best quantitative analysis & achieve accurate results.
Things to consider CPAC 2d
Things to consider CPAC 2d
CPAC 2d - Selects appropriate equipment and measurement strategies in order to ensure suitably accurate results.
Carry out research & write up a plan / practical to accurately measure gas volume
Plan and write up a detailed method in your own words to collect quantitative data (before the practical) that describes how you will obtain accurate results.
Ensure your plan describes how the dependent variables will be measured accurately
