Electromagnetic waves forms a major part of our day to day life. they shape not just our lifestyle but are of utmost importance in some spheres. This ranges from communication to health.

The ILS is based on a topic covered at Form 4 (Grade 12) Kenyan curriculum. It gives a good chance for the learner to investigate and understand the relationship between the frequency of radiation in photoelectric effect and the corresponding stopping potential.

The ILS is based on a topic covered at Form 3 (Grade 11) Kenyan curriculum. It gives a good chance for the learner to investigate and understand the relationship between the angles of incidence and the corresponding angles of refraction as light moves from one medium to another.

Turning effects by forces is central to many spheres in our life. The ILS is meant to help understand the factors that influence the turning effect produced by a force. The evaluations within help to form a good foundation for areas covered later such as (simple)machines.

ILS developed by Richard Njiiri for a topic covered at Form three (Grade 11) Kenyan curriculum. The lesson is to help recognize the basic relationship between current flowing through a conductor and the potential difference across it

This is a lesson on a topic covered at form 3 (Grade 11) Kenyan curriculum Objective Create a relationship between the amount of heating that occurs due to flow of current in an appliance, the amount of current and potential difference across it.  

This ILS gives the chance to investigate the relation between the frequency of a radiation falling on a metal surface and the stopping potential against the photoelectrons. Better understanding and application of the Einstein's equation is made possible using the ILS
