The fascinating physics inside a magazine or a newspaper

This low-cost material demonstration is an example of a discrepant event that is a situation contrary to what the students expect. What the students observe is counterintuitive, creating a moment of conflict in their thinking (Wilson, Lynn, & Nam-Hwa, 2001). In this case, there is a discrepancy between what students observe and what students think should occur. The students are always fascinated with these kinds of unexpected and unpredictable events in science. Discrepant events in science always challenge students to think and analyze the situation and come up with some explanations. Then they will develop eager to learn more about the event and enhance their understanding of science concepts.

The way in which a demonstration in science is presented is a critical and crucial factor in promoting interest in science lessons. This attracts their attention and curiosity to the science lessons. It is also important to provide an opportunity to teacher candidates to create their own demonstrations as part of their professional development (Subramaniam & Hoh, 2008).
