Teaching Outlines

Concept #Introduction to Optical Instruments

Learning objectives

  1. Define optics
  2. Explain how a compound microscope uses convex lenses to make an enlarged image of a tiny object.
  3. To generate ray diagrams to predict the positions and size of images in optical systems
  4. To understand how optical instrument work
  5. To understand the operation of reflecting telescope
  6. Uses of optical instruments

Notes for teachers

Optics is nothing if we don't include experimental instruments. Optics is a very good hands on experience subject which is only possible properly with instruments at hand. In case the instruments are not available then day to day examples such as spectacles, camera, magnifying glass. Even the example of the eye will be of great help as it will help in building an interdisciplinary approach in Physics.

Concept # Types and Uses of Optical Instruments

Learning objectives

  1. Identify the use of convex lens in day-to-day life
  2. Tabulate the differences between a simple and compound microscope
  3. Draw a ray diagram to show the working principal of telescope
  4. State the uses of Optical Instruments

Optics is nothing if we don't include experimental instruments. Optics is a very good hands on experience subject which is only possible properly with instruments at hand. In case the instruments are not available then day to day examples such as spectacles, camera, magnifying glass. Even the example of structure of the eye will be of great help as it will help in building an interdisciplinary approach in Physics.

Project Ideas

  1. Projects about the types of lenses which can be identified easily and are used in day to day life
  2. To draw the ray diagram for the formation of image by a lens
  3. Identify the uses of lenses in day to day life: Divide the class into groups and list down all the ideas on a chart paper
