Features on a world map
We have been identifying the northern and southern hemispheres on a globe and the location of the equator. We have also been learning about latitude and longitude on a world map and finding out their purpose.
We have looked at how the world is represented through different map projections.
Mapping the World
We have been discussing the use of GPS maps from satellite images and the features of street maps. We have been identifying the symbols on maps and what they represent.
We have been discussing how day and night occur through the rotation of the Earth on its axis. We demonstrated this, in the classroom, with a globe and a torch! We have been learning about time zones and finding out what time it is in different parts of the world using the interactive map below.
We have been learning about fossils fuels and how they are classed as non-renewable sources of energy because they cannot be naturally replenished. For example, we have identified how coal is formed over millions of years from layers of dead plant life and once we have run out, it cannot be replaced. This is why people have been investigating more renewable sources of energy such as solar, wind and hydropower. They are also better for the environment, as discussed in the NASA video below.
The Carbon Cycle
We have been learning that all living things are made of carbon. The carbon is recycled through various processes, which are described in the carbon cycle. For example, plants use carbon dioxide and sunlight to make their food and grow. The carbon becomes part of the plant. The plants die and become buried and may turn into fossil fuels. When burned, these fossil fuels release the carbon back into the atmosphere as carbon dioxide.
