A compass can be used to help us navigate. It always points North so we know where East, West and South are in relation to it!
We can use a modified compass to ‘sight’ an object eg. a mountain top and ‘take a bearing’. A bearing is the angle in degrees between North and the object (North is taken as Zero degrees).
This principle can be employed in a classroom or outdoor treasure hunt. The instructions are given as a series of bearings eg. 30 deg,90 deg or 90 deg 10 paces or 10metres.
An interesting classroom activity to get used to bearings and possibly introduce the topic of ‘angles’ is to sit at your desk and take bearings of people and common objects in the classroom. These can then be plotted onto a grid and distances to the objects can be added. This is just like a navigator in a ship or aeroplane ‘plotting their course’.
The next step is to navigate a course around the class visiting several objects on the way before returning home.
