REACTIVITY SERIES
Mrs Devlin has just moved house and wants to put a house number on
the front door for the postman to see clearly. She would like the
number to be made of a nice shiny metal but the area is well known for
acid rain pollution and she is afraid the number might not last. Can you
help her to find the best metal to use. She has the choice of these
metals:- zinc, iron, magnesium and copper.

What do I want to find out?
Which metal reacts most ____________ with acid?
Does any metal ____________ ____________ with acid at all?
Prediction
I predict that ____________ will react most quickly.
I predict that ____________ will react most slowly.
I predict that ____________ will not react at all.
Plan
I will change the ____________ of metal.
I will count the ____________ of _______ produced in one minute.
To make this a fair test I will:
