Literature review

 Short review

Desalination is the process of removing salt from seawater to make fresh water safe for drinking. 
Many countries are using desalination as a way of creating a more reliable water supply that doesn't depend on rain. Desalination produces drinking water and concentrate (the water that contains the salts that were removed in the desalination process, which is sometimes called brine). 
Building a miniature, working model of a desalination system, we can find out about the different variables that affect the system and what the prime variables are in order to collect the most amount of water.

Possible research questions

1) How does the angle of the pipes affect the amount of water collected?
2) How does the flow rate of the water (In) through the pipes affect the amount of water collected? 

3)How does the amount of heat applied to the salt water affect the amount of water collected?

5) Investigation of how the depth of structure underground affects its stability during an earthquake Hypothesis

My hypothesis is that

The ratio of

Height of structure overground : Height of structure underground
                                                         1   :   x

Explanation:
The height of the structure overground should be constant throughout all experiments(Constant variable), whereas the Height of the structure underground will vary(Independent variable)

The higher the value of x, the higher the stability of the structure

4) What is in this Water? Experiments with a Homemade Turbidity Meter Hypothesis

My hypothesis is that the higher the amount of protease in the milk, the more transparent the milk becomes, allowing more light to pass through

3) DNA Fingerprinting Hypothesis

My hypothesis is that for DNA fingerprinting to occur, DNA fingerprinting will allow DNA information to be stored in the machine which can be accessed even in emergencies

2) Cleaning Up Oil Spills Hypothesis

My hypothesis is that the ratio of water to oil will be the highest for the polypropylene pads, and the lowest for the straw.

1) Solar-Powered Water Desalination System Hypothesis

Water desalination:

My hypothesis is that depending on the method of desalination used, salt might not be the only thing removed during the desalination, for example bacteria and so on.

What is Science and the Scientific Method?

Science is the logical and systematic approach to learning and discovering how things work in the universe. Science is our understanding of how the world around us works.

The scientific method is the way to follow a series of steps to find accurate and measurable data.
