Year 10 Science

Earth and Space

SCSA K-10

Key Learning 1: the universe contains features including galaxies, stars and solar systems, and the Big Bang Theory can be used to explain the origin of the universe.

Key Learning 2: global cycles, including the carbon cycle, rely on interactions involving the biosphere, lithosphere, hydrosphere and atmosphere. 

Distances between Stars

Determine the distance between stars in light years

The Origins of the Universe

Identify how ideas about the origin of the universe have changed over time

Explain the origins of the universe and its age using the Big Bang theory

The following videos may help your revision or research:

The Carbon Cycle

Use the picture and the video on the right to understand the following points:

  • carbon is found in all living things and fossil fuels
  • carbon is found in the atmosphere as carbon dioxide
  • carbon dioxide is removed from the air by photosynthesis by plants
  • animals obtain the carbon they need from food
  • carbon is recycled through the soil, all living things and the air 
  • cellular respiration and combustion release carbon back into the air as carbon dioxide
