By the end of this lesson, students will be able to:
Identify different objects that stay on top of water (float) or go down into water (sink).
Show using real objects how some things float on water and how other things sink in water.
Connection to
Lesson summary
This lesson focuses on exploring one of the fundamental properties of water: its ability to interact with objects, causing some to float and others to sink. Understanding floating and sinking is crucial for Primary 2 learners as it builds foundational scientific observation skills and connects directly to their everyday experiences in Nigeria, such as observing objects in rivers, ponds, or even while fetching or washing. This concept is fundamental to understanding how boats, canoes, and other watercraft operate, which are common sights in many Nigerian communities.
Teacher activity
Guides pupils to identify Objects that:- Float in water- Sink in water
Demonstrates to pupils some ways of making objects:- Float in water e.g. stone placed on in flated balloon, human being swimming with the aid of a life jacket or calabash,- Sinking in water (e.g. tying a stone to a feather, cork, etc
In itiates and guides class discussion on other ways of making things float or sink in water
Evaluation guide
The evaluation will be based on the provided performance objectives and evaluation guide.
Formative Assessment Strategies:
Observation during Activities: The teacher will observe students during the group experimentation.
Criterion 1:* Can students correctly identify objects that float or sink during the activity?
Criterion 2:* Do students actively participate in placing objects and observing, demonstrating the concepts?
