The children pointed out that both the map and the globe contain much of the same information, but the map is “flat” and the globe is “round like a ball.” We talked about two-dimensional and three-dimensional representations and introduced the French word, sphère, to describe the shape of the globe. Since the planet Earth is round, the globe is a very accurate model of the Earth. We tried to wrap our rectangular paper map around the globe and found that it didn’t fit. The shape and size of some countries and oceans are stretched on the paper map. We took turns putting our fingers on Canada and turning the globe to the opposite side to see what countries are on the other side of the world. We could not do that on our flat map!
Before the start of the 2018 Winter Olympics, we located PyeongChang on a world map and noticed just how far away South Korea is from Canada. We recently had another look at this map and we brought out a globe to identify some of the similarities and differences. The students noticed how much of the map and the globe is coloured blue. Interestingly, about 2/3 of our planet’s surface is covered by oceans, seas, lakes, and rivers. The children also noticed the variety of other colours and lines that show how the world is divided into approximately 195 countries. After we found Canada, we could further identify the province of Ontario and the city of Guelph. We added some more stickers to the map to show countries where classmates have lived or visited.
