The process begins with a short presentation and discussion session, where the teacher will give an overview of topography maps and 3D printing. This will then be followed by the main part of the lesson - the student workbook. Each student will use 3D CAD software to design a section of the contour model and prepare it for 3D printing, whilst the teacher acts as a facilitator in assisting the students.
The final stage will be a 3D printing demonstration of one section of the contour model. Following the lesson, the teacher can send all models to the 3D printer to complete the 3D contour model.
**the data for the contour model was taken from Google Maps, therefore the scale is an approximation**
This digital pack contains a teacher's guide, presentation, student workbooks, contour sheets and contour sketches.
Each student will require a laptop/ computer with SketchUp software (free), pen/pencil, 30cm ruler and calculator.
The teacher will require a screen for the presentation, a 3D printer with PLA filament and a computer preloaded with slicing software for the 3D printer.
In this lesson students will:
- develop contextual knowledge of topographic maps and contours
- understand how geographical features are represented on maps
- develop an understanding of 3D printers, how they operate and how they are used in various industries
- use mathematical calculations to determine the size that a 3D contour model should be at the scale 1:50000
- communicate geographical information using CAD software and 3D printing
