Hey, here is an overview of my experiemnt

Aim: to investigate energy efficiency of uninsulated steel roofing.

My experiment will be conducted in two parts;

Part A - Colour of steel.
I will test four or five colours of steel, by leaving them in the sun for a period of time (1 hour). I will test how much heat is absorbed by the steel.

Part B - Orientation and positioning of roof
I will test three different types of roof (e.g. flat roof, slanted roof) and leave in the sun for 4-6 hours. I will repeat this four times, for each direction the house can face ( North, South, East, West). I will observe how much sunlight is let into the house* and record the temperature of the house.

Independant Variables Include:

• Amount of time steel rooing is left in the sun
• Angle of roof
• Colour of steel

Dependant Variables Include:

• Intensity of sun
• Heat of steel
• Amount of sunlight let into house*

* My 'houses' will be small models I make. I know someone who is an architect and will be able to obtain the materials from him.
