What should an experimenter do after analyzing data?

• carry out the experiment
• draw conclusion
• observe and infer
• identify the problem

Example: a scientist and his/her occupation... 
Why do archaeologists create maps for their dig sites?

• to photograph artifacts
• to calculate the exact age of artifacts
• to record where the artifacts were found
• to discover artifacts

What is a conclusion that is based on an observation?
