What is the difference between the two? How could they be improved?

I suggest that you take a look at my notes, in particular pages 5-6, 12 (accuracy is on pages 2-3).

In addition I suggest that you read the following articles which were published in Curriculum Support for teaching in Science 7-12. Which is a publication aimed at teachers, distributed to all DET teachers, by Curriculum Services Unit DET. They often have good articles that teachers never seem to pass on to the students.

If after reading these you still need clarification, just post again.
