Mahi Tuatahi ^🔗

1. Collect a sheet from the front
2. Cut up the words and definitions
3. Match them up and glue it into your book!

Ngā Whāinga Ako ^🔗

1. I understand that visible light is made up of different wavelengths of light

Electromagnetic (EM) Spectrum / Tūāwhiorangi Autōhiko ^🔗

Visible light/Aho Kitea ^🔗

Light is the part of the electromagnetic spectrum which can be seen by the human eye.

Ko te whānuitanga o ngā ngaru autōhiko. I tētahi pito ko ngā ngaru roa he pōturi te auautanga (ngaru reo irirangi), i tētahi pito ko ngā ngaru poto he tere te auautanga (ngaru kama). Ko te aho e kitea ana e te karu tangata, tētahi wāhanga o te tūāwhiorangi autōhiko.

Luminous Objects ^🔗

• Luminous objects are objects that give off their own visible light, they are sources of visible light.
• Light waves travel very fast and in a straight line from the source of the light, at a speed of 300,000 kilometres per second (300,000 km/s).
• Task: Name as many luminous objects as you can think of.

What are Colours? ^🔗

• Colours are different wavelengths/roa o te ngaru of visible light
• White light is made up of all the different colours/wavelengths/roa o te ngaru!

Whakakite: Prisms/Ngā Poro ^🔗

• When white light passes through a prism/poro, the different wavelengths are bent at different angles
• This causes them to separate, and all the different colours to become visible

Whakakite: Newton’s Wheel ^🔗

• We can combine the colours of the spectrum to create white light!

What about Colour Blindness? ^🔗

• When your eyes cannot distinguish between different colours
• Genetic condition, inherited from your parents!
