  • 1. Italy IC MICHELANGELO BUONARROTI MARINA DI CARRARA
  • 2. My name’s Pietro, I’m nine years old, I live in Marina di Carrara with my sister and my parents. I attend the forth grade of the primary school and my favourite subject are maths and science . My name’s Haranty, I’m nine years old, I live in Marina di Carrara with my brother and my parents. I attend the forth grade of the primary school and my favourite subjects are maths and science.
  • 3. Level 1- 5-8 years old Subtractive colour mixing Colour wheels in classroom From the primary colours to get white Colour wheels show how visible colours are related. Colour wheels are based on the colour theory, which is based on the physics of light. WHAT YOU NEED: Paper board disk pencil PROCEDURE From paperboard children cut disks and colour them on different ways. They use only 3 primary colours (red, green and blue) And then 6 colours (green, yellow, red, magenta, blue and cyan) Children put together pencil and coloured paper with the stick. They spin them on the table or on the floor and …. white light appears!!! An experience suggested by OŠ Preska, Medvode Šlovenia
  • 4. What we found : When the coloured disk turns around our eyes can’t see each colour but they see only the result of the mixture of the different colours of light. This is the reason why the disk seems to be white-grey, even if on its surface there ar actually seven colours. INVESTIGATIONS: 1. What colours can you see in each case? 2. Does the colour depend on the size of each section? 3. What happens if the bigger part of the circle is coloured with the same colour? 4. What happens if you only have black and white coloured sections? 5. What happens if the colour wheel spins faster (slower)?
  • 5. 8 – 12 years Colour temperatures Equipment: • Red, orange, yellow, green, blue, indigo , brown , black and white paper. • 1 Thermometers • Bright sunny day or light source. An experience suggested by Slovacchia team
  • 6. Aim: To see what colours absorb the most heat. . Method: Line the sheets of paper up under light source, leave them for ten minutes and then get the children to record the temperature on the surface of the paper to see which is the hottest . What we found : Not all the colours have the same temperature: White is the warmest and black is the hottest.
  • 7. You will need: - A prism or a glass of water - A sheet of white paper - A Torch or a ray of sun light Light experiments: RAINBOW An experiment suggested by Spain
  • 8. In Autumn we decide the write place for our eco-garden INSTRUCTIONS: 1)Put the sheet of white paper under the prism 2) Let the ray of light go trough the prism CONCLUSION we can see that white light is made up of a mixture of other colours.
  • 9. Extension: After the explanation, ask the children; “ If we put the colours of the rainbow together again, will we see white light?” Place the magnifying glass between the rainbow and the prism at about 30 cm from the last one, in order to make the seven colours of the rainbow pass through the centre of the magnifying glass
  • 10. Explanation: When the colours pass through the centre of the magnifying glass, they converge and join all together, so we can see the mixture of these colours as white light again.
  • 11. CEIP NARCISO ALONSO CORTÉS (Valladolid) SPAIN Light Experiments by Lourdes Valencia Level 2: 9 - 11 year olds EXPERIMENT 2 ‘ RAINBOW’ You will need: - A piece of card. - Scissors - A prism or a glass of water - A sheet of white paper - A Torch - A magnifying glass When the light goes through the prism or the glass of water, we can see that white light is made up from a mixture of other colours Experiments made ​​ by the pupils’ Comprehensive School "M. Buonarroti"Marina di Carrara secondary school class 1° Secondary school class 1A
  • 12. When the colours pass through the centre of the magnifying glass, they converge and join all together, so we can see the mixture of these colours as white light again. You can see the rainbow in many other situations, such as a CD or ..... a star of crystal ..... Something similar happens when you form a rainbow in the sky. What happens The "white" light is actually made ​​up of different colors that the prism can separate. This effect is called chromatic dispersion.
  • 13. CEIP NARCISO ALONSO CORTÉS (Valladolid) SPAIN Light Experiments by Lourdes Valencia Level 3: 12 - 16 year olds EXPERIMENT 3 You will need A torch viewed through the glass of milky water looks yellowish , like the sun in the daytime. MODEL SKY Experiments made ​​ by the pupils's Comprehensive School "M. Buonarroti"Marina di Carrara secondary school class 1° Secondary school class 1A THE SUN IN THE DAYTIME.
