Nature of Science 3rd

What is the first step a scientist should take when studying something new?

• Write down the results

• Ask questions about what they observe

• Tell others what they found

• Build a laboratory

If two groups measure the temperature of water using the same thermometer and get different results, what could be a reason?

• The thermometer changed between measurements

• The groups measured at different times

• One group didn't wait long enough for the reading

• The water changed temperature by itself

After completing a science investigation, what should scientist do?

• Stop asking questions

• Keep the results a secret

• Explain their results based on their data

• Change the results to match their prediction
