In-text referencing

2.

3 points

Aim

Independent variable stated

Dependent variable stated

Main controlled variables stated

3.

2 points

Hypothesis

Hypothesis stated

This is because... (scientific reasoning)

4.

6 points

Variables

Independent variable identified and ALL trials stated

Dependent variable identified

Explain how the dependent variable is measured (how data is collected)

Controlled variables identified

How each variable is controlled

Why each variable is controlled

5.

4 points

All qualitative data presented in a table

Appropriate and detailed title

Correct rows and column labels

Units present

8.

1 point

Observations of each trial are presented in a table

9.

6 points

Results: Graph

Appropriate and detailed title on graph

X axis labelled correctly with units

Y axis labelled correctly with units

10.

5 points

Discussion

Trend in results described

Results interpreted and explained using scientific reasoning

In-text referencing

Anomalies/outliers identified and explained using scientific reasoning

Reliability, validity, accuracy AND precision explained

11.

2 points

Reliability

Reliability is shown by the consistency of data

Reliability can be improved by repeating the experiment at least 5 times

12.

2 points

Accuracy

Accuracy is the degree to which results are similar to theoretical values

Accuracy can be improved by using more precise equipment

13.

2 points

Precision

Precision is the degree to which a measurement is exact

Using scales with more decimal places. For example, 1.021 g is more precise than 1.02 g

14.

2 points

Validity

Did the method actually test the hypothesis that I aimed to investigate?

Validity can be improved by controlling variables

15.

5 points

Evaluation: Limitations and Improvements

Limitations identified

Relate to controlled variables (validity)

Improvements to the identified limitations are explained

Use scientific research to explain limitations and improvements

In-text referencing

16.

2 points

Evaluation: Extensions

Extensions to the experiment are suggested

Use scientific research to explain extensions

17.

3 points

Conclusion

Was the hypothesis supported by results?

Explain the results in relation to the hypothesis

Validity of the experiment is stated in reference to the aim
