In this lesson students will collaboratively design and 3D print bar charts showing the population growth of 10 countries from 1972 to 2017. The lesson is spread over 3 x 1 hour sessions and involves context about the causes and effects of global population growth along with mathematical calculations, CAD design, 3D printing and demographic research.
The lesson can be incorporated into the study of mathematics, geography, history, design technology or computing and can be adapted for ages 8-15. The curriculum is aligned to NGSS, CCSS and UK National Curriculum standards. A comprehensive list of standards met is included in the lesson platform.
In this project students will:
develop contextual knowledge about the causes of global population growth
develop contextual knowledge about the effects of global population growth
analyse population data and calculate percentage change between different time periods
use Tinkercad 3D modelling software to design a 3D bar chart to relative proportions
use 3D printers to manufacture their 3D bar chart designs
research and explore demographics of individual countries
