Reflection: Developing a Conceptual Understanding Ewww . . . Worms - The Scientific Method In Action (Part 1 of 6) - Section 5: Close - Sharing Data and Concluding Worm Beat


To graph or not to graph that is the question.  The students are pretty effective at following a step-by-step lab procedure and are usually capable of collecting the necessary data, but my experience has been that the students struggle with displaying the data and creating a logical conclusion.  This video clip, Worm Beat Data and Graph, will provide insight to the troubles my students have expressed and a few hints on how to avoid the confusion that we have experienced.  In my opinion, the Worm Beat Lab is a great introductory lab and although students get confused on how to set up their data graph, it is well worth the experience!  Here is the sample Worm Beat Graph.
