Understanding

Exploring Map Projections 

 

This afternoon, we discussed and analysed how various map projections differ in accuracy. We compared and contrasted four map projections: Mercator, Gall-Peters, Robinson and Winkel Tripel. Overall, the most popular map projection that came out in our class discussion was the Winkel Tripel as we found that this projection minimized distortion between area, direction and distance. Did you know that Mercator was accused of imperialism as his map changed the proportions of certain continents? He shrunk Africa and enlarged Europe! 

 

Lexi, Class 13: "Although the Robinson map is the most commonly used in the classroom, I preferred the Winkel Tripel projection as, unlike the others, it created an effective spherical feel to a 2D projection."

Time Zones 

 

Today, we looked at time zones and how the earth has 24 different time zones. Did you know that there is an imaginary line running through the UK called the Prime Meridian? In order to demonstrate our understanding of time zones, we used an atlas to locate places and our mathematical skills to answer a variety of time-based questions. 

 

Ben, Class 13: "It was fun using our mathematical knowledge in a new way as part of our Geography lesson. We worked in pairs to calculate the time-based questions and we even devised our own questions for others to answer."
