What is the first step of the scientific method?

• Analysis

• Question or problem

• Measuring

• Communicating results

Difference between observation and inference.

• Observation is an interpretation of your sorroundings.

• Inference involve senses.

• When you infer you interpret what you observed with your senses.

• This are not skills used by scientists.

What is the last step of the scientific method?

• Measuring

• Analyzing

• Communicating results.

• Drawing conclusions

The summary at the end of an experiment that explains the results. 

• conclusion

• procedures

• materials

• responding variable

Testing a hypothesis often involves a(n):

• answer

• experiment

• problem

• safety check
