You need to think of a question for your experiment!
Remember to put a question mark on the end!

Example:-
What materials are good conductors of electricity?

Prediction means think about what is going to happen in your
experiment.

Example:-
I predict that … metal will be a good conductor of electricity.

You need to give an
answer why you think your prediction is right.

Example:-
because … metal is used in wires in my home.

In every experiment we change 1 thing, this is called the variable.

Example:-
I will change… the materials used in my experiment.

A fair test is when we keep everything the same except the variable. (one thing we change)

Example:-
I will change… the materials used in my experiment.

You will need to say what you are looking for.

Example:-
I will measure … which materials make the bulbs bright and dim, when I make a circuit.

You will need to say what way you will show your results, e.g. table, bar graph, line graph etc.

You will need to say in detail what were the results in your
experiment?

Example:-
What happened? The materials that were made out of metal, made the bulb light up brightly. However, the materials that were not made out of metal did not make the bulb light at all.

You will need to see if your results followed a pattern, and if they did say WHY!

Example:-
Is there a pattern. I found that all the metals made the bulb light up, and the non-metals did not.

You will need to see if any results were odd and did not fit.

Example:-
Are there any results that did not fit the pattern? We tested some pencil lead, and the bulb lit.

You need to look at your prediction and see if you were right!

Example:-
Are your results what you predicted?
Yes, metals were good conductors of electricity.

You need to explain why your prediction was right or wrong.

Example:-
All of the materials that were metal made the bulbs light. All of the materials that weren’t metal did not, except for pencil lead.
