Ratio and Proportion
This activity, from the Institution of Engineering and Technology (IET), helps students develop an understanding of ratio and proportion. This knowledge is applied in subsequent activities when preparing the necessary polymers to be used in the manufacturing of their product and involves calculating how the amounts of ingredients required will change when changing the scale of production. The activity involves exploring what happens if the ratio of water to cornflour is reduced and increased.
The activity has a design and technology and engineering focus, but could also be carried out in a maths context. It should serve as a precursor to the activity ‘Investigating Cast Products’
The activity is part of a full set of resources called D30 and is supported by the the video Amazing D30.
