Science Skills / Investigations

aim

short statement explaining the purpose of the experiment: To determine.... To investigate...

reliability

consistent results/the repeatability of an experiment : If all the results are close together on a map

Validity

Measures what it should, lines up with the aim : If the results are on target (think archery)

what is included in a scientific conclusion

restating the aim

stating whether the hypothesis was supported or rejected

mention specific data, measurements, trends, averages

Explain why the results happened (reasoning)

Explain errors + suggest follow up improvements

What does it mean to identify errors in a scientific discussion?

You say what the errors are, if they are human say what type it is, for example reading equipment wrong, or having poor reaction time

What is accuracy

How close a measured or experimental value is to the true, or accepted reference value

EXAMPLE:How precise the equipment used is, if it could be more precise, eg: using a 10cm ruler to measure 2cm, not using a 1m ruler

What is reliability

The consistent repeatability of an experiment, if the results are in the same area (think archery)

What is validity

Whether an experiment measures what its meant to

EXAMPLE: INVALID would be using a scale to measure people's height
