This activity, produced by Solar Spark, uses "magic dye", a mixture of three different dye molecules. The mixture contains a yellow disperse dye, a direct blue dye and an acid red dye. When a fabric is put into the mixture, the dyes only attach to the types of fabrics they can bond well with. For example, the blue...

This Cre8ate maths activity draws on measuring stretchiness which involves the collection of real data, calculating percentages and experimental design. This resource models one way in which engineers use their knowledge of mathematics to investigate the properties of materials. Here students investigate the...
