Your eyes normally see roughly the same image, with only a small difference between each eye. Even these differences are used by your brain to work out distances to objects. Your brain has evolved to quickly combine these two similar images, to form a 3D scene. This resource is for teachers, parents and carers to use in Sciences (SCN 2-12b / SCN 3-12a) for Second / Third (P5 – S3).

The human visual system has evolved over many tens of millions of years to operate in a world that is mostly lit by white light. Systems in the brain, working entirely unconsciously, compensate for changes in illumination. This resource is for teachers, parents and carers to use in Sciences (SCN 1-12b / SCN 2-11b / SCN 2-12b / SCN 3-12a) for First / Second / Third (P2 – S3).

The principle behind this exhibit is that our brains have evolved to immediately process verbal information, so much so that this information will dominate the interpretation of the list of words, even when we are trying simply to read out the colours of the words. This resource is for teachers, parents and carers to use in Sciences (SCN 2-12b / SCN 3-12a) for Second / Third (P5 – S3).

When you look into the hole in the front of the box, it looks black inside. No light gets into the box, so nothing is reflected back into your eyes. That’s why you can’t see any colours when you look around a darkened room; there is no light to reflect. This resource is for teachers, parents and carers to use in Sciences (SCN 2-11b) for Second (P5-P7).

The Coanda Effect is often misunderstood. It describes what happens when a high-speed jet of air (or liquid) surrounded by the same fluid passes near an object or a curved surface. This resource is for teachers, parents and carers to use in Sciences (related to SCN 2-07a) for Second (P5-P7).
