WE The students of orchids the international school have done some science working models. There were many projects. We have made a projector. We have got a idea to make a projector by- we have projector in our class and we thought that it will be interesting. Here is a description of it:
A projector is used for presentation. There are two types of projector- image projector and video projector. We made a image projector which shows images. first I thought that it is very hard to do but when we tried it was easy.
SCIENCE- It works because of the shape of the lens. There are two types of lens- convex and concave lens. We have used convex lens which helps to see smaller pictures as bigger in size. So, it is the main part of a projector.
