		Which chocolate-covered biscuit bars have the most chocolate covering?

		Be careful if you decide to use knives or any kind of heating equipment.

PLAN	How many different bars will you use? What does each one weigh? How will you remove the chocolate? How will you find out the weight of chocolate?			I WILL NEED	A selection of chocolate-covered biscuit bars. Weighing equipment. Pencil & paper
				I MAY NEED	Food containers. Knives? Heating equipment?
				FAIR TEST	How will you ensure that this is a "fair test"?

	PREDICTION	Can you estimate which of the bars is likely to have most chocolate covering?

PRACTICAL ACTIVITY	Explain how you removed the chocolate. Why did you choose this method? In hindsight, was there a better method you could have used?			COLLECT DATA	Weight of bar with chocolate. Weight of chocolate covering.
				ANALYSE DATA	Different bars weigh different amounts - so how will you decide which has "most" chocolate?
				PRESENT FINDINGS	You could draw a bar chart. You might carry out a survey and compare people's opinions with what you found in your investigation.

	EVALUATE INVESTIGATION	If you were going to do this investigation again, what would you do to improve it (apart from using even more chocolate bars)?
