Week #3
Activity: Exploring our Global Grid System

Now that you've described the location of a spot on a flat surface, play a game of "Locate the Spot" using a sphere!

How does a grid system work on a globe? Find an orange, grapefruit, styrofoam ball, or another spherical object and mark a spot on its surface. Find a partner and try to describe where the spot is located. Next, use a non-toxic marker to draw horizontal and vertical lines to create a grid system on your sphere.

  • Use the Guiding Questions page to help you get started and to think about how latitude and longitude lines are used on a globe.
