Creating a light refraction science working model using a plastic transparent bottle filled with water, a candle, and white paper to show reflection is a straightforward and effective way to demonstrate the principles of refraction and reflection.

Here’s a step-by-step guide:

Materials Needed

  • Plastic transparent bottle (empty and clean)
  • Water
  • Candle or flashlight
  • White paper or wall
  • Marker or tape
  • Scissors
  • Match or lighter (for candle)
  • Optional: Food coloring (for visual effect in water)

Step by Step Guide on Making of light refraction science working model experiments

1. Prepare the Bottle

  1. Remove Labels:
    • Ensure the plastic bottle is clean and free of any labels that may obstruct visibility.
  2. Fill with Water:
    • Fill the bottle almost to the top with water. Leave a small gap to prevent overflow when inserting objects.

2. Set Up the Light Source

  1. Light Source Placement:
    • Place the candle or flashlight on a stable surface behind the bottle.
    • Ensure the light source is positioned so that its flame or beam can shine through the water-filled bottle.

3. Positioning and Observation

  1. Adjust Bottle Position:
    • Position the bottle between the light source and a white piece of paper or a plain wall.
    • Mark or tape the positions to ensure consistency and accuracy during the experiment.
  2. Observe Initial Setup:
    • Turn off the surrounding lights to enhance visibility of the experiment.
    • Note the initial path of light from the candle or flashlight through the water-filled bottle onto the white paper or wall.

4. Demonstrate Light Refraction

  1. Light Refraction:
    • Observe how the light beam bends as it enters and exits the water in the bottle.
    • Explain to viewers that this bending of light is called refraction, caused by the change in speed as light travels from air to water and back to air.

5. Show Light Reflection

  1. Light Reflection:
    • Position the paper or wall at an angle behind the bottle to observe any reflections of light.
    • Move the paper or wall until you can see a clear reflection of the candle flame or flashlight beam.
  2. Discuss Reflection:
    • Explain that reflection occurs when light bounces off a surface, in this case, the water surface inside the bottle, and then onto the paper or wall.
