You have experienced using a microscope and a magnifying glass, haven't you? Now, watch the videos of an activity that you can do on your own to experience making and using a telescope. 

What do you think? Can you make your own telescope? 

Now, read the notes below to get more informations about the applications of optical instruments. Please update your note book 😊. We will have a discussion and Q&A session after this.
