Light and Colour

Today we are studying light and colour. Remember not to get confused with paint colours! Can you list the three primary colours and the three secondary colours?

Did you know that your eye also have sensor cells for the three primary colours?

What does the diagram below show about how filters work?

What is the one colour of light that leaves DON’T absorb?!

  1. Today we were learning about light and what colours we actually see! Red Green and blue are the primary colours. Red and blue makes magenta, red and green make yellow, blue and green make cyan and all of them together make white.

  2. In science we are learning about light. Your eyes actually sense only 3 colours, green, red and blue.

    Question 1 answer:Red, blue and green (primary)
    Magenta, cyan and yellow (secondary)

    Question 2 answer: It shows that filters can not reflect colours that do not make up that colour.

    Question 3 answer:Green

    Thank you Mr Phillips for teaching us!

  3. If you mix green and red you get yellow. If you mix green and blue you get cyan. If you mix red and blue together you would get magenta. If you mix all the primary colours together you would get white. The science primary colours are green, blue and red. And all the secondary colours make white as well.

  4. The three primary coulurs are green, red and blue. If you add all of them together it would make white. If you add blue and green together it makes cyan and if you add red and green together it makes yellow.

  5. When a white light is shone at a red filter the light will come out red because white is made out of green, blue an red and the red filter only lets the red light through.

  6. I definitely learned something new. Did you know that trees are not green they are reflecting green. They are actually red and blue! That is really surprising. Would you think that?

    • All of the primary colours in science add up to white and the secondary colours add up to white as well. The primary colours in science are blue, red and green. Most people think it’s yellow but that’s in art not science; yellow is made by red and green.
