What Affects the Shape of a Volcano?

What Affects the Shape of a Volcano?


Aim:
The aim of this experiment is to see what factors affect the shape of a volcano. The factor I will change is the temperature of the magma.

Plan:
I plan to use a beaker and fill it with 150cc of water. I will then place the beaker on a gauze, which is placed on a tripod. Under the tripod I plan to place a heatproof mat and a Bunsen burner. In to the beaker with water in it, I will place a boiling tube witch is half full of my magma substitute. The substance I will use instead of magma will be Phenyl-Salicylate as it has a low melting point of 42oC. I will then melt the Phenyl-Salicylate to different temperatures. I will put 1CC of the melted Phenyl-Salicylate on to a wooden board, which is covered with tin foil to make the surface smooth. The board will be set to an angle of 30o and held at that angle with a clamp stand and clamp. I will then measure accurately how far the Phenyl-Salicylate travels down the board before it solidifies....
