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.

Who is the course for?

This course is intended for anyone with an interest in numbers and making scientific observations. It does not require mathematical skills or any previous experience of studying the subject.

There are no special requirements for this course but you may like to find a simple calculator in a drawer or on your mobile phone to help you with some of the maths calculations.
