The initial teacher Demonstrate/Replicate is to provide students an opportunity to observe the process and results. When replicating the teacher demonstration, students are developing the skills required to become proficient with the experiment and building personal knowledge about scientific concepts.

As students look at changing variables, the PEOE comes into play. Students are able to Predict what will happen (not just guessing) as they have had experience with the process and concepts. At this point, students are drawing from prior experience to make an educated prediction.

Predict - Use the 'If....then...' statement
Explain - Why do you think this? (prior experiences, topics covered in class, theories studied)
Observe - Both qualitative and quantitative
*as a teacher, I would provide my students with intentional instruction here - a video, shared reading, newspaper article that confirms and continues to develop the personal knowledge students have built for themselves.
Explain - Student understanding of experiment. Linked with prediction, initial explain, observations and directed teacher lesson.
Each section of the PEOE corresponds to the typical four sections of a lab report. A basic organizer is included in the document as a starting point for early transitions to lab report writing.
Introduction - explaining the problem, stating a hypothesis, providing background knowledge.
Methods - image of setup, steps to replicate the experiment precisely, explain the variables
Results - provide a data table or graph of numerical data, explain qualitative observations (pictures / images)
Discussion - Make conclusions (hypothesis is supported or not supported), sources of error, connection to prior knowledge and understanding.
