Keywords

  • Float
  • Sink
  • Objects
  • Water
  • Light
  • Heavy

Set Induction

  • Show a bowl of water and two objects (e.g., a stone and a plastic bottle).
  • Ask pupils to guess what will happen when each object is placed in water.

Entry Behavior

Pupils may have observed objects floating or sinking in water during daily activities like bathing or playing.


Learning Resources and Materials

  • A large bowl of water
  • Light objects (e.g., plastic bottle, rubber ball, sponge)
  • Heavy objects (e.g., stone, key, coin)
  • Flashcards with drawings of floating and sinking objects

Building Background/Connection to Prior Knowledge

Pupils may have observed some objects staying on top of water and others sinking when placed in water. This lesson will help them identify why this happens.


Embedded Core Skills

  • Observation
  • Critical thinking
  • Listening
  • Speaking
  • Sorting and classification

Learning Materials

  • Bowl of water
  • A variety of objects (light and heavy) for demonstration
  • Flashcards showing floating objects

Reference Books

  • Lagos State Scheme of Work for Nursery 1
  • Basic Science Textbook for Early Learners

Instructional Materials

  • A clear bowl of water
  • Real objects like plastic bottles, rubber balls, coins, stones, and sponges

Content

  1. What are Floating and Sinking Objects?
    • Objects that stay on top of the water are called floating objects (e.g., plastic bottle).
    • Objects that go to the bottom of the water are called sinking objects (e.g., stone).
  2. Why Do Objects Float or Sink?
    • Light objects (e.g., rubber balls) float because they are less heavy than water.
    • Heavy objects (e.g., keys) sink because they are heavier than water.
  3. Examples of Floating Objects
    • Rubber ball
    • Plastic bottle
    • Sponge
    • Wooden stick
  4. Activity: Sorting Floating Objects
    • Pupils will place objects into the bowl of water and observe which ones float and which ones sink.

Presentation

Step 1: Revision of the previous lesson.

  • Review air and land transportation, asking how aeroplanes stay in the air, then introduce floating and sinking in water.

Step 2: Introduction of the new topic.

  • Place a light object (plastic bottle) and a heavy object (stone) into the bowl of water. Ask pupils to observe what happens.

Step 3: Activity Time.

  • Provide pupils with a pile of objects. Allow them to test each object in the water and sort the floating objects from the sinking ones.

Teacher’s Activities

  • Explain the concepts of floating and sinking with demonstrations.
  • Show examples of floating objects.
  • Guide pupils in testing the objects and sorting them into floating and sinking categories.

Learner’s Activities

  • Listen to the teacher’s explanation and observe the demonstrations.
  • Participate in testing objects in the water.
  • Identify floating objects and sort them correctly.

Assessment

  • Ask pupils to name one object that floats.
  • Observe how they perform the sorting activity.
  • Test their understanding by asking questions about why some objects float and others sink.

Evaluation Questions

  1. What is a floating object?
  2. What is a sinking object?
  3. Name one object that floats.
  4. Name one object that sinks.
  5. Why do light objects float?
  6. Why do heavy objects sink?
  7. Does a sponge float or sink?
  8. What happens when a stone is placed in water?
  9. Can you name one thing that floats in your home?
  10. Which is heavier: a stone or a rubber ball?

Conclusion

  • Review the concepts of floating and sinking objects.
  • Encourage pupils to observe objects around them to see which ones float or sink.
  • Praise them for their participation in the activity.
