Step Four: Raw Data Table, Experiment, and Uncertainties
By the end of this step you will have:
✔︎ Created your raw data table with correct headings
✔︎ Carried out your experiment
✔︎ Collected your data and displayed it in your raw data table
✔︎ Written a short paragraph justifying your raw data table uncertainties
Creating your raw data table
Carrying out your experiment and collecting your raw data
Explaining and justifying your raw data uncertainties
Actions
➜ Create your raw data table
➜ Carry out your experiment and collect your raw data
➜ Explain and justify your raw data uncertainties
Checklist
✔︎ I created my raw data table
✔︎ My raw data table headings include the name of and letter symbol for my variables
✔︎ The letter symbols for my variables are in italics
✔︎ My raw data table headings include units
✔︎ My raw data table headings include uncertainties
✔︎ My independent variable uncertainty is given to the same number of decimal places as my independent variable values
✔︎ My raw data table has space for at least three trials
✔︎ I carried out my experiment and filmed all my trials (if applicable)
✔︎ I recorded my data in my raw data table
✔︎ I saved my completed raw data table online
✔︎ My dependent variable uncertainty is given to the same number of decimal places as my dependent variable values
✔︎ I explained and justified my raw data table uncertainties, referring to my data collection method
✔︎ In my explanation above, I mentioned one or more of the conventions used when determining uncertainties
Questions to ask your teacher
✤ Are the raw data table uncertainties clearly explained and justified?
✤ Are the raw data table headings fully correct?
✤ Are the independent and dependent variable values given to the correct number of decimal places? (Considering the number of decimal places in the uncertainty values)
