Thematic Maps and GIS

Hurricanes are giant spinning storms, and scientists study them with pictures taken from space. In this activity, you get to be the scientist. You watch satellite movies that show a hurricane swirling, and you look at special images that stack different information on top of each other, like rainfall, wind, and temperature. Each layer tells you something new about the storm. Your job is to spot patterns: Where is the wind strongest? Where does the most rain fall? What does the calm center, called the eye, look like? After you study the images and label what you see, you compare your ideas with diagrams from books or the internet to check your work. This is exactly how real weather scientists use layered maps and satellite pictures. They do not just look at one picture. They combine many layers of information to understand the whole storm and predict where it will go next.

From 2013 to 2017, California went through a serious drought, which means it did not get enough rain or snow for a long time. In this activity, you investigate the drought like a detective using maps, satellite images, and photographs. The maps show where water became scarce, and the satellite pictures let you see changes from space, like reservoirs shrinking and green farmland turning brown. As you look at this evidence, you practice a key map skill: reading spatial patterns. You can ask questions like, Which parts of California were hit hardest? Did the dry areas spread or shrink over the years? How did the land change as the drought went on? This is the same kind of thinking geographers do with thematic maps. Instead of just showing where places are, these maps show data, like how much water an area has, so people can spot problems and decide how to help.

Soil is not the same everywhere, and that matters more than you might think. In this unit, you work in a small group to examine real data about soils and map it out. When you put the data on a map, patterns start to appear. Maybe one kind of soil clusters near rivers, or another shows up where the climate is dry. Your group looks for these patterns and talks about what might cause them. Then you connect what you found to bigger ideas about how Earth works, adding details to a concept map that links soil, water, plants, and people. Finally, you discuss why these patterns matter for real life, like where farmers can grow food or where building might be risky.

Greenland is covered by a huge sheet of ice, and scientists keep a close eye on it because it is changing. In this activity, you look at real measurements collected from Greenland and map where the ice is shrinking the most. The data shows a clear spatial pattern: some areas lose ice quickly while others change more slowly. You get to think about why, considering things like ocean currents and warmer air. Then you follow the water. When ice on land melts, it flows into the ocean and sea levels rise. You explore how this affects different places around the world, especially low lying coastal communities, and you think about why some countries can prepare for rising seas more easily than others.
