The 'predict-observe-explain' (POE) strategy
requires students to carry out three tasks:
Task 1: A physical situation is demonstrated to
the students who are then required to predict the result of a specific change to the physical situation.
Students are also asked to explain their prediction.
Task 2: When the students conduct the experiment, the students are asked to
describe what they see.
Task 3: Students are required to reconcile any conflict between prediction and
observation
