Chemical garden

The chemical garden is a well‐established experiment from the chemistry of salts, solubility, diffusion, and solutions. The nice thing is that if metal salts are put in sodium water glass solution, it can lead to an effect reminiscent of plants growing. This growing process can be observed and analysed. In the end...

Chameleon bubbles

Chameleon bubbles are formed when a sodium alginate solution is dropped into a calcium chloride solution.  The bubbles are filled by an acid‐base indicator solution; so, adding the beads to acids or bases leads to colour changes inside the bubbles by diffusion and pH change. Students can learn about acids, bases,...

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...
