Year 5

Welcome to Newton Class

Welcome to Year 5 (Newton class) ! We chose Sir Isaac Newton as our influential figure, as we had been studying forces as part of our science topic and we felt that Newton had made a significant impact upon the world.

Isaac Newton is considered one of the most important scientists in history. Even Albert Einstein said that Isaac Newton was the smartest person that ever lived. During his lifetime Newton developed the theory of gravity, the laws of motion (which became the basis for physics), a new type of mathematics called calculus, and made breakthroughs in the area of optics such as the reflecting telescope.


Scientific Discoveries

Isaac Newton made many scientific discoveries and inventions throughout his career. Here is a list of some of the most important and famous ones.

  • Gravity - Newton is probably most famous for discovering gravity. Outlined in the Principia, his theory about gravity helped to explain the movements of the planets and the Sun. This theory is known today as Newton's law of universal gravitation.
  • Laws of Motion - Newton's laws of motion were three fundamental laws of physics that laid the foundation for classical mechanics.
  • Calculus - Newton invented a whole new type of mathematics which he called "fluxions." Today we call this math calculus and it is an important type of math used in advanced engineering and science.
  • Reflecting Telescope - In 1668 Newton invented the reflecting telescope. This type of telescope uses mirrors to reflect light and form an image. Nearly all of the major telescopes used in astronomy today are reflecting telescopes.


Many historians also believe that Newton invented the cat flap !  Supposedly, his inventions were always being disturbed by his cats scratching at the door to be let in. A frustrated Newton ordered a carpenter to cut holes in his wooden doors, so that his cats could come and go without disturbing him.
