Practical ratio investigation

Class 5 have been investigating ratio.  We considered how ratio was used in our everyday lives and whether it was important to follow a recipe.

We baked buns in groups, altering only one ingredient at a time.  One group baked a sample batch as a control; one group trebled the amount of sugar; one group tripled the amount of flour; one group tripled the amount of butter and another doubled the quantity of eggs.

We had to use our measuring skills, organise our work and follow a recipe.

Afterwards we evaluated the success of our baking by observing the finished products, feeling and tasting them.  Surprisingly, everyone had different favourites. We considered the effect changing each ingredient had had.

We produced a written report and created graphs and pie charts using Excel to show our results.
