| + | * '''Process (How to do the activity)''' |
| + | #Demonstrate the dispersion using a prism and recombination of the light |
| + | #Students must do this experiment in groups |
| + | #The teacher must demonstrate carefully how to position the prism, how to observe rays in light experiments |
| + | #students must be able to draw ray diagrams showing the split of the spectrum |
| + | * '''Developmental Questions (What discussion questions)''' |
| + | #When the light falls on the prism, what did you expect to see? What happened? |
| + | #What are the colours you see? What is the order of the colours? |
| + | * '''Evaluation (Questions for assessment of the child)''' |
| + | #From the incoming beam of light, which colour showed the maximum angle of dispersion? (This question can be picked up later to discuss wavelengths and electromagnetic spectrum) |
| + | #If you change the direction of the incoming light, what happens to the dispersion? |
| + | #Observe the accuracy of the diagrams |

− | #Light travels as electromagnetic radiation; with waves of different wavelengths

− | #Light interacts with material particles in discrete packets called photons

− | #Different wavelengths are associated with photons of different energies

− | The objective here is to enable students to understand that light can be thought of as a wave or as particles. Different models of light explain different phenomena. It is important to get a sense of the history of how light was understood, how electromagnetism was understood and how light is the result of continuously oscillating electric and magnetic fields.
