Subject: Basic Science

Class: Primary 2

Term: Third Term

Week: 6

Topic: Air Floatation

Sub-topic: Meaning, Objects that Float in Air, and Characteristics of Floating Objects

Duration: 60 minutes

Behavioural Objectives:

• By the end of the lesson, pupils should be able to:
  • Explain the meaning of air floatation.
  • Name objects that float in air.
  • Identify characteristics of objects that float in air.

Key Words: Air floatation, balloons, kites, bubbles, light, shape

Entry Behaviour:

• Pupils know about air and may have seen balloons or kites floating in the air.

Learning Resources and Materials:

• Balloons, kites, bubbles, paper planes, pictures of birds or other flying objects.

Building Background / Connection to Prior Knowledge:

• Review the topic of air and its uses in the previous lessons. Discuss how we use air to breathe, and that it also helps some objects float.

Embedded Core Skills:

• Observation, discussion, critical thinking.

Reference Books:

• Lagos State Scheme of Work

Instructional Materials:

• Balloons, kites, bubbles, paper planes, and pictures of floating objects.

Content:

• Introduction to air floatation and the different objects that float in the air.

Air Floatation : a. Meaning b. mention objects that float in air; c. identify the characteristics of these objects that can float in air;

a. Meaning:

• Air floatation is when objects stay up in the air.
• These objects can float because of the air.

b. Objects that float in air:

• Balloons: Filled with helium, they float up. 🎈
• Kites: They fly high in the wind. 🎏
• Birds: Birds flap their wings and glide in the air. 🦅
• Paper planes: Made from paper, they glide when thrown. ✈️
• Bubbles: Bubbles can float in the air. 🫧

c. Characteristics of objects that can float in air:

• Lightweight: Objects that float in air are usually light.
• Air-filled: Balloons and bubbles have air or gas inside.
• Streamlined shape: Kites, birds, and paper planes have a shape that helps them move smoothly through the air.

These objects can float because they are light and can move easily through the air. 😊

Class Activity Discussion :

1. What is air floatation?
   • Air floatation is when objects stay up in the air.
2. What makes objects float in the air?
   • Air helps them stay up and move around.

5. What kind of gas is in floating balloons?
   • Helium gas.
6. What is another example of something that floats in air?
   • Bubbles float in the air.
7. Why can birds float or glide in the air?
   • Birds flap their wings to move and glide in the air.
8. What helps a kite float in the air?
   • Wind helps kites float in the air.
9. Why do paper planes float in the air?
   • Paper planes are lightweight and have a good shape for flying.
10. How do bubbles float in the air?
    • Bubbles are filled with air and are very light.
11. Why do floating objects need to be lightweight?
    • Lightweight objects can stay up and move easily in the air.
12. What shape helps objects float in the air?
    • Streamlined shapes like a bird’s wing or a kite’s design.
13. What can you use to make a paper plane float in the air?
    • You can use paper and fold it into the right shape.
14. Can all objects float in the air?
    • No, only light objects with the right shape can float.
15. Why is it fun to play with things that float in the air?
    • It’s fun because they can move around and you can control them.

These questions help you understand air floatation and how different objects float in the air! 😊

Presentation:

Step 1: The teacher revises the previous topic, which was on the uses of air.

• Discuss how air helps us breathe and helps plants grow.
• Meaning, Properties and Uses of Air Basic Science Primary 2 Third Term Lesson Notes Week 5

Step 2: The teacher introduces the new topic of air floatation.

• Explain that some objects float in the air.
• Introduce different objects that can float in the air, like balloons, kites, and bubbles.
• Explain how these objects float because they are light and have the right shape.

Step 3: The teacher allows the pupils to give their own contributions and corrects them when and where necessary.

• Ask pupils to share what objects they know that float in the air.
• Discuss the characteristics of these objects (e.g., lightness, shape, gas inside).
• Use the instructional materials to demonstrate how different objects float in the air.

Teacher’s Activities:
