Year 5 - Anders Celsius Class


Anders Celsius was born in Sweden on November 27, 1701.  His earliest research concerned the aurora borealis (also known as the northern lights, which are an unusually spectacular illumination of the night sky).  

The work for which Celsius is best known is his creation of a hundred-point scale for temperature.  He  invented the Celsius (or centigrade) thermometer scale, which set the freezing point of water at 0° and the boiling point at 100°. 

When Celsius introduced his scale in 1747, it was the reverse of today's scale, with the boiling point of water being zero degrees and the freezing point being one hundred degrees. A year later the two constants were switched, creating the temperature scale used today. Celsius originally called his scale centigrade (from the Latin for "hundred steps"). For years it was simply referred to as the Swedish thermometer. In 1948 most of the world adopted the hundred-point scale, calling it the Celsius scale.

Welcome Letter


Year 5 had an amazing fun packed few days in Brancaster, Norfolk learning about the environment and how to protect it. Here are some photographs from their time away.

IPC and Science

Our Science topic this term is Earth and Space. We will investigate the earth and other planets, the sun and solar system and the moon. We will investigate how the planets move around the sun and how the moon rotates around the earth. In addition, we will explain why the sun rises and sets each day and the process of this. The IPC topic for this term is Mission to Mars which relates to Science. We will research the process of travelling to Mars and what this would involve.
