In Science, our Grade 4 class has begun learning about the Earth’s spheres and how they are all connected. We are discovering that changes in one part of Earth can cause changes in many other parts as well!
To begin our learning, we watched the video How the Wolves Changed the Water. This video helped us see how one animal can have a big impact on the land, plants, water, and even rivers. We talked about how wolves affected the biosphere, geosphere, and hydrosphere, and how everything worked together as a system. This helped us understand that Earth’s spheres do not work alone—they are connected.
Next, we shifted our thinking to humans and discussed how people can also impact Earth’s spheres. We shared ideas about how human actions can change the land, air, water, plants, and animals. This led us into conversations about climate change and how changes in temperature can affect living things and environments around the world.
To deepen our understanding, we began reading the book Two Degrees. As we read, we will explore how climate change affects different parts of the Earth and the people and animals who live there. We will continue to connect the events in the story back to the Earth’s spheres and think about how small changes can lead to big impacts.
We are excited to keep learning, asking questions, and making connections as we explore how our planet works, and how we can help take care of it!
