One of the wonders of nature-Bioluminescent planktons

You may have seen this natural phenomena if you are living near a sea shore or if you have walked along the shore at night.You will see small stars shining in the sea,like they have fallen from the sky :) .But do you know what is this actually?It's a biological process.Those star like lights are planktons.Not ordinary planktons,they are bioluminescent planktons.They can glow in the dark.But how?

Certain creatures on land and sea can produce light through chemical process inside their bodies.It's known as bioluminescence.It is a result of a chemical reaction which produces light,chemiluminescence.When some chemical
s are mixed it produces energy which excites other particles on vibration and generate light.So the glow in planktons are caused by several oxidation reactions set off by a catalyst called luciferase.

These planktons are a main food source of aquatic organisms such as fish.So planktons use bioluminescence as a way to evade predators.

Nature is amazing,Isn't it? :)

How to get 90+ for GCE A/L Chemistry paper..

Well for most of the people doing A/Ls in science stream, chemistry is a nightmare, especially for physical science students. So today I'm going to tell you how to write to a chemistry paper in a much different way than you always do. Well it worked for me,and you should test this way with a model paper or in a term test before you go to exam.This saves time and also you can easily score 90+.

How to survive A/Ls in 3 months...

Today is the first of May and there are exactly three months until GCE A/L exams begin. I intend to help people who has realized this and started panicking and feeling lost, but not only A/L students but also any student with any upcoming exam can use these tips to ace your exam. I will first explain why most of us usually wait until the day before deadline to do stuff. It's explained by Parkinson's law which states that " Work expands so as to fill the time available for its completion". What it means is, if we are given a week to finish a task we will finish it within the week and if we are given an year to finish the same task we will spend the whole year doing it. Well that's how usually us, lazy humans work. Now that you know what happened there is no time to regret about how we procrastinated on unnecessary things etc. Now it's time to damage control. I will not gurantee you will get 3As by following these. (It's possible depending on

Good books for students studying for GCE A/L examination...

As we all know A/Ls is a very tough exam and you will not be able to finish it successfully by just studying.It needs practice,timing and all.So the best way to do it is do exercises and improve knowledge,i did A/Ls in physical science stream and in sinhala medium,so based on my experience i will recommend anyone to use following books.There may be books better than following list,but books below were used by me. Chemistry almost every book by hemachandra basnayaka Akabanika rasayanaya by Aruna Bandara (there are two books for inorganic chemistry,these books will help you in for the doubts you will have in doing mcqs) Akabanika rasayana pilibanda gunathmaka ha pramanathmaka wishleshanaya by Ranga gunarathna(this also will help you in mcqs) Organic chemistry by jayathilaka(this book is very good and it will help you to understand concepts in organic chemistry better) Physics Prof D.D.N balo dayas' books yanthra vidyawa by lakshaman dissanayaka(questionsin this book are
