Bam! The Strength of Rocks

Objectives/Goals  I chose to study rock fracture because the San Francisco Bay Area is a major earthquake center. An experiment on the strength of rocks would help us understand earthquakes and understand ways of building structures to withstand them.  I tested the fracture strength of four rock types: granite, soft granite, marble and slate, to investigate the question, "What type of rock can withstand the most pressure before fracturing?"  My hypothesis was that granite would withstand the most pressure without breaking.  Methods/Materials The strength of a rock is the amount of pressure it can withstand without breaking. There are three kinds of forces in breaking of materials: tension (pulling apart), compression (pushing together) and shear (sliding apart).  When a bar of material is pushed down, the bending causes compression on the top and tension on the bottom.  One standard measure of strength of a material, independent of the size of th

Make a Rocket

Rockets are fascinating!  They soar into the sky and help us know many secrets. Are you fascinated by rockets? If your answer is yes, you would be interested in this activity. The rockets that you can make safely will not go very far, perhaps much less then the rockets we enjoy on the Deepawali day. But then you will agree, the fun and excitement to make your own rocket has a totally different dimension.  The basic principle of rocketry is Newton's Third Law of Motion, that is, "For every action there is an equal an opposite reaction".  A big rocket uses chemicals to release an intense stream of gas out its tail end that propels it upwards.  A fuel is used in a rocket to produce this gas through some chemical reaction. The rocket fuel is sometimes liquid, and sometimes solid.  But, in all cases, a gas is ejected from the tail of the rocket. The first kind of rocket that we can make is propelled by a very safe gas - carbon dioxide.  The fuel it uses is

Make a Periscope

Are you familiar with the word "submarine"? A submarine is a kind of boat that moves underwater. Submarines are common crafts for the Naval forces of any country. But, while moving underwater, submarines need to know where they are with respect to other objects on the surface of water. The device they use to do this is called a periscope.  Periscopes are optical instruments that can afford submariners a limited though vital visual picture outside their windowless hull. Traditionally, periscopes offered the submerged submarine its only glimpse of the outside world. Classic English war movies have also made them the submarine's most familiar feature.  For most of us, who are unlikely to come across submarines in real life, a periscope can make it possible to see round corners and over the heads of crowds during processions or at sporting occasions. In a periscope, two mirrors are arranged at 45 degrees to each other. One mirror captures the rays of light from t
