Alright the class has been given an assessment task handout. Its a prac.
These outcomes to be asessed are things I personally think you could preprepare (study) for.

The test could be anything from determining cell size to determining the optimal pH for enzyme activity, so its fairly vague.

What I need help with is gathering information that could/would be usefull for the following outcomes.

1.Justifies the appropriateness of a particular investigation plan: ?

2. Evaluates ways in which accuracy and reliability could be improved in investigations: ? Uhh better equipment and repetition, anything else?

3. Asesses the validity of conclusions from gathered data and information:?

4. Explains why an inestigation is best undertaken individually or by a team: ?
individually-can trust yourself/not rely on others in case of misinterpretations or accidents?
Team - Possbly better organisation due to division of jobs?

It would be appreciated if you could add some points that could help in the prac outcomes above.

Here's some info to get it started;

Areas of accuracy:
-accurate measurement of variables
-appropriate use of equipment e.g. Measuring equipment i.e. measuring cylinder
-averaging of results
-controlled variables

Areas of reliability:
-control
-range of values for independent variable
-repetition or replication
