Seeing Temperatures

This activity allows students to investigate how images are produced from data streams by using first a spreadsheet and then an image-processing program. They then go on to see how the usefulness of such a monochromatic image may be enhanced by using lookup tables and calibration. The materials used focus on the...

Building Images

In this activity, students create colour images from satellite data. This allows them to study how different surfaces reflect different wavelengths of light, how coloured images are created using an RGB model, and how band combinations can be chosen to examine a particular landscape effectively.

Data-logging with BBC micro:bits and MakeCode for modelling with Excel and GeoGebra.

Recent developments in MakeCode now make data-capture from micro:bits very simple via the USB cable.  The data can be graphed in real time in MakeCode and exproted as CSV files.  Using tools such as Excel and GeoGebra's Spreadsheet View, the data can be manipulated, analysed and modelled.  With a pair of...
