Before we start our decomposition let’s have a quick reminder of the rules involved when solving maths equations. There are a lot of steps involved when solving this equation, so the best way to calculate an answer is to decompose it. In KS2 the key concepts of decomposition will be revisited, however there will be a much stronger link to mathematics and computer science whilst learning takes place.Ī fantastic example of a decomposition activity at KS2 would be to look at mathematical functions and break them down into their individual components. This is the heart of decomposition: taking a complex and seemingly impossible problem and analysing how best to find a solution.

Now let’s find out whether our character has blonde hair:Īs you can see, by asking a series of targeted questions we were able to establish that the chosen character must be Christian, as there was nobody else on the board that met our criteria.īefore our decomposition of this problem, we were faced with quite a daunting task – how do we work out who our opponent has chosen in a group of 16 people? However, by breaking the problem down into a series of smaller, easier-to-manage problems, we were able to find a solution with relative ease. Next we could find out whether our character has hair: Having narrowed down the options the next question asked could be “has your character got black hair?” the answer to which would be “no”. This has immediately narrowed down the remaining choices on the board: The first question could be “have you chosen a male character?” to which the answer would be “yes”. I have decided that Christian is my character, and now it is down to the other player to try and work out whom I have chosen. Let’s play a round using the character named Christian: The former means "the degradation of a substance by chemical or physical processes", e.g., hydrolysis the latter means "the metabolic breakdown of materials into simpler components by living organisms", typically by microorganisms.In the game Guess Who, the aim is to try and find out which character the other player has picked by asking a series of questions to try and narrow down the possibilities to only one. Decomposition can also be a gradual process for organisms that have extended periods of dormancy.One can differentiate abiotic decomposition from biotic decomposition (biodegradation).
The science which studies decomposition is generally referred to as taphonomy from the Greek word taphos, meaning tomb.
Although no two organisms decompose in the same way, they all undergo the same sequential stages of decomposition.
Organisms that do this are known as decomposers or detritivores. Animals, such as worms, also help decompose the organic materials. Bodies of living organisms begin to decompose shortly after death. The process is a part of the nutrient cycle and is essential for recycling the finite matter that occupies physical space in the biosphere.
