Let’s do Science!
Good morning, everyone. We are learning about light and some of its properties today and, you know what? We are going to try a couple of experiments to check how things actually work. Ready?
Let’s start by reading very carefully the information on pages 104 and 105. Be careful, it’s a lot. We have talked about many of these things previously, though and you should be able to deal with it. You can click on the pictures to load the audio tracks.
Well, let’s make a quick review. We have read about how light can be reflected (which means that light bounces against the surface of an object as a ball would bounce) or refracted (light changes its direction when going from a particular medium to another). We have also read about lenses, which we can make to build telescopes or microscopes, for example. The last section is about colours and how we perceive them.
I want you to open your notebook now and complete exercises 2 and 4 on page 105.Well, that was the boring part. Let’s have some fun now! There are two very simple experiments you can do to check how refractions works and how the seven colours in the rainbow turn into white light. You have a loooong weekend ahead, why don’t you spend some time trying them?
That was it! I’ll provide you with the right answers next time. Until then, bye bye!
