Identify variables and formulate hypothesises

1. How does the fuel burnt affect the different pollutants produced?

Independent Variable: The fuel used

Dependent Variable: Temperature of the flame and amount of pollutants produed

Constant Variable: Amount of fuel used, amount of oxygen provided,

Hypothesis: Liquid Fuels burn cleaner than Solid Fuel

2. How does the weather conditions affect the rate of condensation?

Independent Variable: Amount of wind, weather conditions (raining will cause humidity levels to rise), surrounding temperature

Dependent Variable: Rate of condensation

Constant Variable:  atmospheric pressure, size of condenser

Hypothesis: Rate of condensation will increase with high humidity level, and decrease with high wind conditions.

3. How does the surface area affect the rate of condensation?

Independent Variable: Surface area of object

Dependent Variable: rate of condensation

Constant Variable: material of object, temperature of object, wind condition

Hypothesis: The larger the surface area, the faster the rate of condensation

What is Science and the Scientific method?

Science is the study of how variables work and behave through observation and experimentation.

The process of observing and experimenting so that one may understand phenomenas, as well as the acquiring or correcting of previous known knowledge using a body of techniques is known as a scientific method. For it to be termed"Scientific",  it must have evidence to support principles of science.
