What are we often doing in chemistry experiments which helps us keep track of variables?

• Trying to correlate trends or patterns in data.

• Making observations.

• Recording data in a chart and/or graph.

• Reflecting and writing to what extent our results are supporting our hypothesis.

After you have posed a research problem question to investigate and researched background information on the chemical being tested in a system, what do you form, which acts as a critical part or "core" of your experiment?

• research problem question

• hypothesis

• conclusion

• procedure

Which of the following orders of doing scientific research is the least informative?

• Stopping your report on your scientific conclusion is always the last step of scientific method

• After your scientific conclusion, you should reflect on your experiment as to whether it answered your original research problem question

• After your scientific conclusion, you should reflect & explain any errors you experienced

• After your scientific conclusion, you should pose other follow-up questions that you could test on the given subject
