This resource will let students see pink elephants.

When the human eye is exposed to one colour for a relatively long period of time, the cone cells will become saturated with that colour. Once the eye is exposed to a broad range of colours again, the brain will pick up weaker signals from that colour and...

This resource contains ten instant maths ideas using spreadsheets to solve mathematical problems. Mathematical topics explored include: * solving equations to complete a think of a number puzzle * completion of magic squares * exploring different sequences * the ‘Rich Aunt’ problem * an exploration of cubic graphs...

This resources provides students with an introduction to the topic of technical textiles. It provides an overview of what technical textiles are and why we might use them for different products. The specific classifcations of technical textiles...
