RISE AND FALL OF STARS
Published on 2011-06-06 13:20:00
Physics is so dear to me, although many students and science teachers alike do not feel good with it. To some, it is boring and full of Maths. Others just do not find it attractive to their intellect, I should say. > read more
ROCKS OF THE EARTH
Published on 2011-05-24 14:25:00
Materials like chairs, woods, carpets, clothes, glass, metals amongst others; are materials found in or on the Earth. Chemical reactions helped manufacturers to make these raw materials become useful, attractive, and durable. The earth’s crust provides abundant amount of minerals, rocks, and fossil fuels. A mineral is a single substance, which has a chemical name and formula. A rock is a mixture of different minerals. Examples of minerals are limestone and rock salts. Their purest from are cal [..] > read more
FRUITY DNA EXPERIMENT
Published on 2011-05-20 12:05:00
Cells are composed of nuclei, and nucleus is considered the largest single structure within the cell. It is further composed of separate structures called chromosomes which are responsible to carry information for reproduction or for sort of genetic analysis in laboratories. These chromosomes are made of a more complex polymer called DNA or Deoxyribonucleic acid. Although DNA is a very large molecule, you could not see it with your naked eye, unless you know and you have a great deal with it.T [..] > read more

FERMENTATION ACTIVITY
Published on 2011-05-15 14:39:00
This practical can be done as a demo or class experiment provided you have enough materials for the whole class.Fermentation is the process of breaking down of food by micro-organisms using anaerobic respiration. Yeast is a single-celled fungus, and reproduces by growing buds out of the cell and feeds itself on sugars like glucose. In the process of fermentation, the yeast makes alcohol (Ethanol) and carbon dioxide. To illustrate it better, consider the equation belowThe Equation:GLUCOSE --> [..] > read more
AN ENDLESS SCIENCE
Published on 2011-05-08 12:32:00
Are you still struggling to reconcile the disparity between Darwin’s evolution theory and the Divine Creation? Perhaps most of us are recurrently, mystified about the feasibility of time travel and time machines. How about the existence of parallel universes, do you find it amazing or rather irrational? Still interested around alien invasion or you may be more engrossed reflecting the issues of global warming and its menace that we are already living through. Plus, the revolution of technology [..] > read more
LET’S BURN YOUR MONEY
Published on 2011-03-07 16:38:00
What? That sounds insane, but remember there is a load of crazy stuff in science that we can learn and enjoy from. I do not mean burning your money is fun, neither I would give in to the challenge if I am not confident I could actually have it back in exactly the same condition as it should be. You can practice this using ordinary white paper or filter paper cut into note-like sizes, that is to build up your confidence that it truly works. So, have fun and burn your money away.Burning money is i [..] > read more
