Activity investigates actual how a blue print represents actual dimensions.
Objectives
Measuring actual dimensions from a blueprint
Estimated Time
45 minutes
Prerequisites/Instructions, prior preparations, if any
- The students should have knowledge about scale drawing.
- They should know about scale factor.
- They should understand that a scaling factor should be maintained as constant throughout the sketches.
- Students should be able to read and understand a scaling factor.
- They should be able to find a scaling factor and create a scale drawing.
- The activity on using standard measuring instruments should be done prior to this activity.
- The students should have been introduced to area, calculations and unit conversions.
Materials/ Resources needed
Non digital: Graph sheets, scale, pencil
Process (How to do the activity)
