Activity Overview

Youth engineer a model of a LiDAR technology to capture the shape and height of a landscape (topography). 

Guiding Question

How can we gather information about topography? 

Youth Will Do

  • Use bundles of straws as models to represent how remote sensing with laser technology can produce topographic maps. 
  • Develop ideas for changing the design of the straw model to better map the surface of objects.  

Youth Will Know

  • Engineers often use models to represent the technologies or materials they are investigating and test their technologies in model conditions. 
  • Engineers design technologies that capture complex data to make it easier to understand and use for different purposes. 
  • Engineers must evaluate the quality of the data their technologies produce.
