A Discrepant Event (DE) is one that causes an unexpected contradiction in students’ prior knowledge and experience of a scientific event in support of conceptual understanding (Wetzel, 2008). Students use problem-solving and critical-thinking skills in order to explain the phenomenon. Inquiry-based instruction that uses such strategies as discrepant events has the potential for developing scientifically literate students (Beerer & Bodzin, 2004). Similarly, this discrepant event will be the root of each module in order to develop a conceptual understanding of science literacy.
