Greece: the hottest day last summer

     The whole world knows the hottest days which leads to the acidification of the seas. Europe suffers bigs heatwaves, especially in Greece.  This summer in Greece it was one of the warmest summer, there were a lot of restriction for the security of people.  There were so many forests on fire, the firemen were very active this summer.

AUSTRALIA IN FIRE

 AUSTRALIA ON FIRE

Australia is a very hot country , because of it there are many fires. They will have to seriously develop ways or news technologies to fight that even thought the surfaces are really large and so the cost will be high. 

Many firefighters were killed, the population who were living beside had to breathe the noxious smoke ( in the forest there are human wast, plastic...). 

Babies may have malformations later. As other consequences animal will disappear and also different plants.

Farmers will lose their farm and their fields so there will be no more food and Australia will have to take it food from other countries.

Australia needs some more money.

The hottest day in Australia:

Australia

Because of the heat the fields were dry and animals couldn't eat, some of then died.It was so hot that houses were broken a little and begin to degrade. There were many forests which were on fire and lots of natural habitation animals were lost.Peoples who worked outside passed out it's too expensive to rebuilt every things and to hire people. For the first time it was more than 50°C, that was so high; To conclude be careful during the summer for nature,animals, people and shouldn't forget to drink enough water

color creation with primary and secondary colors

To do this expérience, we have need a white light as well as 6 different plastic filters which represent the 3 primary colors which are red, blue, green as well as the 3 secondary colors which are magenta, yellow and cyan.

this experiment shows how to create colors with the primary and secondary colors.
To create these colors we put 2 color filters in front of the light which create a new color. Let's take an example, if we put a filter of a primary color like red in front of the white light then a blue filter, when we bring together the blue and red beam we obtain a secondary color which is magenta. Then we do the same with the other primary color and we notice that its creating the secondary colors. Conversely, using the secondary colors gives the primary colors.
We notice that if we gather the beams of light from the three secondary colors we obtain black, conversely if we gather the beams of light from the three primary colors we obtain white

How to make a rainbow?

 

To make a rainbow we need :a light, a prism and if you want a black cover.For better result go in a dark room. 

To make a rainbow you need to place the black cover in front of the light and place the prism in front of the light. To see the rainbow better you can place a white paper in front of the light. 

To make more than one rainbow you can use a black cover with two or three slit.

This phenomenon appends when the light touch a substance with a different refrative index. 

How to make a rainbow

To make this rainbow we used a white light, a cover with a slit and a prism.

For a better result we did this experience in the dark. The light refracts when it travels at an angle into an environment with a different refractive index and the prism as a different refractive index than the air so when the light shines trough the prism it diffract and make a rainbow.
