Assignments, unit 6.

Today you should have a completed assignment ready to hand in. Make sure that you've checked all sections are included in your experiment write-ups, and that you have it in a plastic pocket with your name somewhere obvious. Once you've done that, complete the following questions on the maths section (unit 6) that we're about to start:

1. What is maths used for in Science?
2. What is the difference between accuracy and precision?
3. What is reliability in relation to data?
4. Why are data loggers often better for collecting data?
5. Do you think boys or girls in the class are taller on average? How would you calculate this?
6. What are the independent, dependent and control variables in an experiment?
7. What factors might affect the accuracy of measurement when finding someone's height?
8. Extension - Take a piece of scrap paper and draw a target on it. Try dropping a pen into the middle of the paper 5 times. Are your results accurate? Are they precise? How could you calculate this?
