Basic Science: Understanding Numbers

Find out how you can use numbers to describe the natural world. Start making sense of everything from atoms to oceans.

Basic Science: Understanding Numbers

Get to grips with scientific numbers and relate them to the real world

On this practical course you will start thinking like a scientist, by using numbers to describe and understand the natural world.

You will gain the skills you need to understand and communicate scientific numbers, including averages, percentages and negatives. You will also find out how to relate them to the real world – whether the size of the Greenland ice sheet or the number of molecules in a raindrop.

The course was produced with the kind support of Dangoor Education. You may also enjoy Basic Science: Understanding Experiments.
