Story Two:
Isaac Newton (1642–1727)

Trinity college

This stop explores the life of Isaac Newton who was a student and professor at the university. Many people have heard that he was sitting underneath a apple tree when an apple fell on his head and he had an amazing idea about how gravity worked.

He also wrote a book called the Principia Mathematica, full of mathematical explanations and was a scientist enjoying alchemy.

He made a big contribution to another branch of science called optics. He studied prisms and how they worked. He worked out that light looks white but is made up from lots of different colours. Modern telescopes such as the Hubble space telescope use the same idea!


Activity Two: Make a colour wheel

Isaac Newton designed the colour wheel based on the light spectrum. He linked the seven colours of the rainbow to the seven notes of the musical scale.

Children can colour in the ‘colour wheel’ in the activity sheets  trying to remember the seven colours of the rainbow in the correct order.

• Show the activity card with a picture of Newton’s colour wheel.

Newton was trying to create a way of linking light and colour to an idea about harmony spreading through all of God’s creation.

The way the colours are set out around the wheel started artists thinking about how colours work together. Sometimes colours on opposite sides of the wheel are called complementary colours, because they look good together.
