Y9 Science Exam Review

Aim: the purpose of the investigation .

Hypothisis: How you think the experiment will go and why you think this.

Method: A simple, workable plan of what you will do – and can be repeated by another person. Usually written as a numbered list.

Results: a table of the measurements you have taken with any processed data.

Conclusion: what your results tell you linked back to the aim and hypothesis and state whether your hypothesis was proved or disproved.

Dissusion: Reflect on the experement and figure out what you did wrong and what you could do better next time

Independent Variable: The variable you can manipulate and change.

Dependent Variable: The variable that you measure throughout the experiment.

Controlled Variable: Is the variable that you keep the same throughout the experiment

Fair Test: A fair test is a test that controls all but one variable when attempting to answer a scientific question.

Reliability: Doing more than one test to make sure your information is reliable.

Accuracy: Techniques used to increase accuracy. This can include reducing parallax error, reducing ‘zero’ error, suitable units of measurement

Three Things I Could Improve On:

1. Making the paper helicopter better

2. Making sure my graph is done correctly

3. Putting a bit more effort into the CL5 questions
