Lesson Plan: Light, Sound, and Energy

 

Theme: How We See and Hear

Duration: 5 Days (35–40 mins each)

⭐ Day 1 – Introduction to Light

Learning Objectives

  • Students understand what light is and why we need it.
  • Students identify natural and artificial sources of light.

Concepts

  • We need light to see things.
  • Natural light sources: Sun, fire, stars
  • Artificial light sources: Bulb, torch, lamp, candle

Activities

  • Light Source Sorting: Show pictures; students sort into natural and artificial.
  • Torch Activity: Turn off classroom lights briefly and use a torch to show how light helps us see.

Materials

  • Pictures of sun, bulb, lamp, stars, fire
  • Torch

Assessment

  • Oral: “Is the sun natural or artificial?”
  • “Name two artificial light sources.”

⭐ Day 2 – Shadows and Shadow Play

Learning Objectives

  • Students understand that light forms shadows when blocked.
  • Students explore how shadows change shape.

Concepts

  • Shadows are formed when an object blocks light.
  • Shadows can be big or small depending on the light position.

Activities

  • Shadow Play:
    Use a torch and hands to make animal shapes on a wall.
  • Object Shadow Activity:
    Hold objects (toy, pencil, hand) in front of the light and observe the shadows.

Materials

  • Torch
  • A plain wall
  • Small classroom objects

Assessment

  • Ask: “What makes a shadow?”
  • Students show one shadow shape.

⭐ Day 3 – All About Sound

Learning Objectives

  • Students identify different types of sounds.
  • Students differentiate loud and soft sounds.

Concepts

  • Sound is something we hear.
  • Loud sounds: drum, whistle, thunder
  • Soft sounds: whisper, rustling leaves, soft music

Activities

  • Sound Experiment Stations:
    1. Tap a metal spoon on glass (soft sound)
    2. Clap hands loudly (loud sound)
    3. Shake a box of rice (soft sound)
    4. Tap a drum/table (loud sound)
  • Sound Guessing Game:
    Teacher makes a sound → students guess the object.

Materials

  • Spoon, glass, rice box, drum/table, paper

Assessment

  • “Identify if this is loud or soft” (teacher demonstrates sound).

⭐ Day 4 – Energy in Daily Life

Learning Objectives

  • Students understand the simple meaning of energy.
  • Students recognize where energy is used in daily life.

Concepts

  • Energy helps us do work.
  • We use energy for moving, playing, lifting, running, reading (light energy).
  • Sun is the biggest source of energy.

Activities

  • Movement Game:
    Students act out: running, jumping, pushing a chair → teacher asks “What gave you energy?”
  • Energy Chart:
    Students identify actions that need energy vs. actions that don’t.

Materials

  • Action cards
  • Chart paper

Assessment

  • Oral: “What helps us run?”, “What is the biggest source of energy?”

⭐ Day 5 – Review + Light & Sound Observation

Learning Objectives

  • Students revise concepts of light, shadows, sound, and energy.
  • Students distinguish between sources of light and sound.

Activities

  • Flashcard Revision:
    Students sort cards into:
    • Light Sources
    • Sound Sources
  • Shadow Challenge:
    Students create any shadow and explain it.
  • Loud or Soft Quiz:
    Teacher makes sounds → students show thumbs up (loud) or down (soft).

Assessment

  • Students classify:
    • Sun → light
    • Drum → sound
    • Bulb → artificial light
    • Whisper → soft sound
  • Worksheet (optional):
    • Circle natural light sources
    • Match sound to loud/soft
    • Identify energy-using actions

Homework

  • Draw one natural and one artificial source of light.
