This Proportional Scaling video also includes:
It is not as simple as scaling. MIT researchers explain that a micro engine cannot just be a proportional scaling of a working larger engine. The Math at the Core: Ratios resource compares the proportions involved with the surface area and volume when a figure is scaled.
- Research how an engine generates electricity
- Create a composite three-dimensional figure and have the class determine the surface area and volume of a scaled version of the figure
- Individuals should understand the calculation of surface area and volume of a cube
- Provides teaching tips
- Includes a diagram to illustrate the comparison of the scale of surface area and the scale of volume
