How to Make a Geosynchron. We learn in school that the earth rotates around its axis once in a day , and that it also revolves around the sun once in a year. A geosynchron model helps us to understand this. In my last article, Discover it 3, I promised to tell you how to make a geosynchron. Take a large spherical globe and place a tube through it as was described in my last article for doing the Dhruva tara experiment. You can use the plastic globe models of the earth which are available in most schools for this [...]

DISCOVER IT - 3 Last month we saw how to make a powerful solar telescope using a simple pocket mirror, a dark room, and a large plastic ball filled with mud or sand. I had asked you to do an experiment with this solar telescope to get a large image of the sun on which you might see sunspots. I also asked you to write back to Indradhanush describing what you did and what you saw. In this article, I was planning to tell you what you can learn by observing sunspots. But there is only one problem. So far [...]

THE SUN IN YOUR HANDS Remember the Magic Mirrors experiment I asked you to do last month. Did you perform the experiment ? If you did, then did you observe the following puzzling facts ? 1.When the reflected image is taken up on a nearby screen, it is the same shape as the mirror. Like this : ( Here put figure of a circle, a square and a triangle ) 2.When you take the image on a wall far away, all the images are round in shape , like this ( here draw three circles). Since you are all [...]

DISCOVER IT - 1 This year is being celebrated as an important anniversary year for science . One century ago, in the year 1905, young Einstein published four pathbreaking papers in physics. Each of these papers was of historic importance. In honour of this great year in the history of Physics, we are celebrating its centennial as “The International Year of Physics”. Here at Indrandhanush we will be observing this year in a special way, with a journey of discovery. Would you too like to become a great scientist, like Einstein, or Archimedes, like Aryabhata, Marie Curie or C.V.Raman [...]
