Primary 4 – Science: Chemical Reactions in Jelly Cooking Process
In Science, P4 students delved into the concept of chemical change by exploring how substances interact and react to form new substances. They began by learning that a substance is made of one type of matter and that when substances are mixed, they may undergo a chemical reaction to create something entirely new. Building on this foundational knowledge, students applied their understanding through a hands-on activity: observing the Jelly Cooking process.
During the experiment, students identified the ingredients involved—jelly powder, sugar, and water—and observed how they were mixed together. As the mixture was heated on a stove, they noted how the heat caused a reaction, resulting in the formation of jelly pudding. This process allowed students to connect the abstract concept of chemical change to a familiar and observable activity.
The jelly cooking activity reinforced the idea that a chemical reaction occurs when a substance undergoes a transformation and creates a new form, such as the transition from liquid ingredients to a solid jelly. The students also related this experiment to other examples of chemical reactions they had previously studied, such as the burning of a candle.
By engaging in this experiment, P4 students developed a deeper understanding of chemical changes and recognized that such reactions are a part of their everyday lives. This hands-on learning experience encouraged them to observe, analyze, and connect scientific concepts, making the topic of chemical change both relatable and meaningful. ***
