This is a quick read article on the nature of science. I especially liked how the authors remind us that science knowledge is not absolute - that the study of science is ever changing as new evidence is uncovered. This is an important point in the teaching of science - to teach the nature of science and not just the scientific concepts. I like the activity suggestion provided. However, I would not complete the activity as suggested. I would try to find another tool - something other than a hanger (maybe a metal spoon) to use instead. Great idea, but I would prefer using a different piece of equipment. Overall, a great read - highly recommended.

In the introduction to this article these authors point out five valid points about what science is and focus on the difference between observation and inferences. Students test a variable using this piece of equipment. Students learn that empirical data is observational and not made from inferences. A grade level is not stated but due to cognitive thinking this activity would be best used in upper elementary students.
