Lesson Duration: 45 minutes
Grade: K1
Preparation Time: 15 minutes
Learning Objectives:
- Children will be able to identify objects as heavy or light.

Lesson Procedure
3 mins - Welcome Time
• Sing the "Hello Song" (
• Introduce today's topic: "Today we're going to be Weight Explorers!"
5 mins - Discovery Chat
• Show two objects - one heavy (e.g., a book) and one light (e.g., a feather)
• Demonstrate lifting each object, exaggerating the difference
• Introduce the words "heavy" and "light"
• Ask children to repeat: "The book is heavy, the feather is light"
10 mins - Hands-On Challenge 1: Heavy or Light Game
• Prepare a box with various objects (e.g., toy car, balloon, small stuffed animal, plastic cup)
• Children take turns picking an object from the box
• Ask them to guess if it's heavy or light before lifting it
• After lifting, they say: "The [object] is [heavy/light]"
• Place objects in two groups: heavy and light
10 mins - Hands-On Challenge 2: Balancing Act
• Introduce a simple balance scale
• Demonstrate how it works with obviously different weights
• Children take turns placing objects from the previous activity on each side
• Encourage predictions: "Which side do you think will go down?"
• After each attempt, discuss what happened and why
10 mins - Hands-On Challenge 3: Fruity Weight Surprises
• Prepare a variety of fruits and vegetables of different sizes and weights (e.g., a large lettuce, a small apple, a big watermelon slice, a handful of grapes, a small potato)
• Introduce the activity: "Let's play a guessing game with our fruit and veg friends!"
• Show children two items at a time, asking: "Which do you think is heavier?"
• Encourage children to make predictions based on size
• Use the balance scale to compare the weights
• Highlight surprising results, e.g., "Look! The small potato is heavier than the big lettuce!"
• Repeat with different combinations
• Conclude by saying: "Sometimes big things can be light, and small things can be heavy. Isn't that surprising?"
2 mins - Wrap-Up
• Recap: "Today we learned about heavy and light. Some things are easy to lift, and some are harder!"
• Sing the "Goodbye Song"
