Science Project on “Inside the Eye”, Project Experiment Topics on Light, Sound, Maths, Optical Illusion for Class 8, 9, 10 and 12 Students.
Inside the Eye
Materials Required:
- Hand magnifying glass
- Modelling clay
- A few small toys
- High-intensity desk lamp
- Adhesive tape
- A strip of white paper
- Table
- A pair of scissors
- An adult
Images are magnified through binocular and telescope lenses. However, we often forget that the first tool used in astronomy is the human eye. Objects reflect light that go in through the pupil, then pass through the lens. This focuses the image at the back of your eye and you actually get to see the object. The back of your eye is known as the Retina.
This experiment will demonstrate how these lenses work. With the help of modeling clay, hold a magnifying glass upright on the table. At the other end of the table, place a few small objects, like toys. Get an adult to plug in the lamp, which should shine on the toys. Now next to the magnifying glass, hold a 3- inch stiff paper, on the side opposite to the lamp and toys. Keep moving the lens away as the objects come into focus. This will be the correct image distance.
The paper strip should now be rolled into an eye-shaped curve. Tape the two ends to the magnifying glass.
