We observed the worms response to touch, their behavior in water versus on moist filter paper, and we even got to see the blood traveling through the worms body under the microscope!
The purpose of the lab was to understand how to gather facts and make clear observations and then make inferences based on those facts. Often times, we make inferences and describe behaviors based on the "Human Point of View." For example, if we observed that the worms were tangled together and squirming, we may fall into the trap of describing this behavior as "wrestling or fighthing" because that is how humans may behave.
Observations are facts that are made using one or more of the five senses. Scientific observations must be specific!
Inferences are explanations or interpretations based on the observed facts.
