Often at the beginning of a topic, you will either observe a demonstration or watch a video or be given a description of a discrepant event. After sufficient materials have been covered, you will be challenged to explain it.
However, unlike in MYP science, your write-up won’t be graded according to any specific criteria. Some times the discrepant event write-up may count like a quiz. Some times, it may be graded and count towards your final grade. Some times, it may lead to a design investigation. What a given Discrepant Event requires will be made clear at the time it is demonstrated.
Regardless, the Discrepant Events contain guiding questions to help you.
IGCSE year 1 (Form 4) Discrepant Events are labeled F4 and year 2 (Form 5) F5.
Expectations for discrepant events that are common to both forms are different, as will be evident from the accompanying questions.
