Aim: To figure out what the reaction will be, of acid from things from the ocean.

Hypothesis: it might fizz and change colour of the acid.

Independent Variable: (what will you measure? what will be affected)

We're going to try out different types of acid.

Dependant Variable: (What will you change)

Weigh mass before and after

Independent variable: (What is the range you will use?)

1 Mol                       Coral

0.1 Mol                   Chalk

Dependant variable: (How will you measure?)

Use the scales to measure the grams.

Controls: (What will you keep the same? How will you keep it a fair test)

Same concentration of the acid and same amount of acid each time.
