===Notes for teachers===

''These are short notes that the teacher wants to share about the concept, any locally relevant information, specific instructions on what kind of methodology used and common misconceptions/mistakes.''

This is a very interesting topic for children and the teacher must be prepared to take a lot of curious and interesting questions. Illustration and experimentation will go a long way in explaining a lot of concepts in optics. Day to day examples of spectacles and magnifying glasses etc will be very helpful for the students. May be to get the students excited we can also gave sessions with binoculars and telescope was and when the available.
