We have already discovered that the Sun is just a common star among millions of stars in the universe !! It is very important for us because it illuminates and warms the earth. His light and warmth allow plants, animals and other living beings to survive on our planet !! Without the sun there would be no life on earth. It is very bright because it is a giant ball of bright, luminous gas. Sunlight takes only eight minutes to reach the earth, but it is still strong enough to damage our vision. So you should never look directly at the sun and wear sunglasses. We also have to be careful with the remains of bottles and other glass that we leave in the forest. As we can see from our experience: "Does the sun emit heat?", Many fires start because the sun is very strong and when it warms up it can cause a fire. That's why we always have to recycle the garbage and put it in the right ecopoints! If you want to do this experience it has to be in a safe place, you cannot look directly into the light and the presence of adults is mandatory. We need a lamp (sun) and a magnifying glass. When the lamp light falls on a spot in the newspaper through the magnifying glass, it will cause the newspaper to ignite after a few minutes.
