Anyway, What is light?
Light always emanates from a light source and is a form of energy. Strictly speaking, light is what is known as electromagnetic waves. There are different forms of electromagnetic waves. X-rays are also electromagnetic waves, but we cannot see them with our eyes. They are only referred to as light or light rays when they become visible.
Light rays spread in all possible directions, travelling infinitely far and at very high speeds. Nothing can travel faster than light. It covers a distance of up to 300,000 kilometres in one second.
No colour without light - additive and subtractive colour mixtures
A basic distinction is made between so-called light colours and body colours. Body colours are based on the properties of material bodies, such as the leaves of a plant. Light colours, on the other hand, appear in the light spectrum.
There are therefore two types of colour mixtures. One is called additive colour mixing. It gets its name from the fact that the colour is created by adding two or more coloured light sources. If, for example, green and red light are mixed, an interface is created at which the two light colours mix to create the colour yellow. When red and blue are mixed, the colour magenta (purple) is created.
Subtractive colour mixing, on the other hand, is when radiant energy is removed from a light source by filtering or absorbing it. The remaining light forms a mixed colour when superimposed. Therefore, the more body colours are mixed, the darker the result - light is removed with each new body colour. For example, if you put yellow and blue in front of a white light source, you get the colour green.
Experiments with light and colours for children
With our 69-piece "Light and Colours" experiment set you can carry out exciting experiments with your children to teach them about light, colours and optics. The experiment kit comes with 43 pages of illustrated instructions. When carrying out the fascinating experiments, you will learn interesting facts about the formation of colours and their perception in light and shadow. This is the ideal set for science lessons from Year 1 onwards to carry out experiments with light and colours in primary school! You will be able to carry out the following experiments, for example:
- Using two mirrors to observe how the different results of additive and subtractive colour mixing can be seen directly next to each other
- Mixing coloured light in different ways
- Experiencing complementary colours as replica of the coloured foils and boxes
In addition, as suggestions many other observations in nature are described. With these experiments on light and colours, both children and adults will be amazed and will see colours from a completely different perspective in the future.
How do we see colours?
A leaf is green, for example, because it emits green rays of light. Rays of light usually come from the sun. The seemingly white rays of light from the sun are a mixture of different coloured rays of light (the so-called spectrum). The leaf swallows all but the green light rays from the multi-coloured sun rays. It sends these away again and they reach our eyes. Accordingly, without light there would be no colours at all.
Experiments with colours for primary school
Packed full of entertaining experiments on the topics of light and shadow, optical perception and colour theory, the "Colour & Light" experiment set introduces children to the world of optics. Dots pulsate, become larger and smaller and yet remain the same size. You can perceive movement where there is none, or encode secret messages - using colours only. If you want to find out more about optical illusions, tricks with colours and games with light and shadow, this is the right product for you.
