Measuring the Earth

September 20, 2023 @ 12:00 pm 1:30 pm PDT

Geometry literally means “Earth measure”. Join us as we meet along a common meridian to celebrate math and measure our planet.

With some simple geometry and some friends on Zoom, we can measure the polar circumference of the Earth. This task was first done by Eratosthenes (276 BCE – 195/194 BCE). We will watch shadows along the meridian that runs north-south through San Mateo CA, Portland, OR, Seattle, WA, and Prince George, BC. Using these measurements we will calculate the distance around the earth through the poles. We will explore how to make a connection with a partner along your longitude line and how to run the activity.

We are honored to be joined by the education team at The Exploration Place in Prince George.
