Primary 1 – Science: Look! Floating and Sinking Objects
Primary 1 students continued learning about the movement of objects. They discovered that things that have never been alive cannot move by themselves, but they can move when a force such as a push or pull is applied. Building on their understanding of forces, students were introduced to a new concept of sinking and floating. They learned that an object floats when it stays on the surface of the water, and sinks when it moves below the surface.
To deepen their understanding, students began to predict whether certain objects would sink or float when it is placed in water. They observed that size alone does not determine whether an object sinks or floats. Somehow some large objects floated, while some small ones sank. Through this process, the students practiced making predictions, observing outcomes, and classifying objects based on their behavior in water.
Students then conducted a hands-on experiment to test their predictions. Working carefully and following classroom rules, they placed different objects in water to observe which ones floated and which ones sank. During the activity, they discussed why certain objects behaved differently and reflected on the properties of materials that might affect floating and sinking. This stage encouraged them to think critically and reason scientifically, connecting what they saw to what they had learned about forces.
After the experiment, students cleaned up their materials responsibly and reflected on what they discovered. They realized that the world around them is full of examples of floating and sinking, from boats on water to pebbles sinking in a pond. By connecting classroom learning to real-life situations, students began to understand how science helps explain everyday phenomena. They also learned the importance of safety, cooperation, and responsibility during experiments.
It was an exciting and meaningful science session for the young learners! Through this activity, P1 students demonstrated curiosity, teamwork, and careful observation. They learned not only about forces and water movement, but also practiced thinking like real scientists; asking questions, testing ideas, and drawing conclusions.
