Fun with a magnifying lens in Light, Shadows and images – Class 6 Science Experiment

Chapter Name: Light, Shadows and images

Activity Name: Fun with a magnifying lens in Light, Shadows and images

Activity Description:

In this experiment, you will use a magnifying lens to form an image of a tree on a white drawing sheet. You will compare the image formed through the magnifying lens with the image formed through a pinhole camera.

Required Items:

1. Magnifying lens
2. White drawing sheet
3. Tree or object to be imaged
4. Light source

Step by Step Procedure:

1. Set up your experiment in a well-lit area.
2. Place the white drawing sheet on a flat surface.
3. Position the tree or object you want to image in front of the white drawing sheet.
4. Hold the magnifying lens between the object and the white drawing sheet, making sure it is a few inches away from the object.
5. Adjust the position of the magnifying lens until you see a clear and focused image of the tree on the white drawing sheet. You may need to move the lens closer or farther from the object to achieve a clear image.
6. Once you have a clear image, observe the characteristics of the image formed on the sheet.

Experiment Observations:

1. The image formed on the white drawing sheet will be inverted, meaning it will be upside down compared to the actual tree.
2. The image formed through the magnifying lens will be clearer than the image formed with a pinhole camera.

Precautions:

1. Handle the magnifying lens with care to avoid any damage.
2. Ensure the light source is bright enough to create a clear image.
3. Do not look directly at the sun or any other intense light source through the magnifying lens, as it can cause eye damage.

Lesson Learnt from Experiment:

Through this experiment, you have observed that the image formed by a magnifying lens is inverted on the white drawing sheet. Additionally, you have noticed that the image formed through the magnifying lens is clearer than the image formed with a pinhole camera.

This demonstrates the ability of a magnifying lens to gather and focus more light, resulting in a sharper image. Understanding the behavior of light and the properties of lenses can help us comprehend how images are formed and how optical devices function.
