Today, we looked at the different ways in which we use rivers. We first started by exploring the rivers and canals that flow through Doncaster. This included the River Don, Stainforth and Keadby and New Junction Canals. We recognised a couple of the photos which were taken in Doncaster. Then we looked at the uses of rivers and canals. We found that we can use rivers for transportation, leisure, irrigation, hydroelectric power, drinking water, habitats and ecosystems, and fishing. We then matched the use to the impact that it can have on the environment. Some of them had both positive and negative impacts on the environment. For example, people who use rivers for leisure activities such as kayaking and canoeing are improving their physical and mental health but they could pollute the waters and destroy habitats.

In our lesson, we used our prior knowledge about tectonic plates and began to deepen our thinking around what they could cause. We discussed how the movement of tectonic plates can cause earthquakes. There are three different tectonic plate boundaries where earthquakes occur: convergent, divergent and conservative. We then demonstrated our newfound knowledge in an experiment. We used crackers and cream to show how the tectonic plates move at the different boundaries. At the divergent plate boundary, the tectonic plates move apart. At a convergent plate boundary, the plates move together and the denser oceanic plate subducts under the lighter continental plate. Finally, at a conservative plate boundary, tectonic plates slide past each other. Friction happens and pressure builds up which is released as an earthquake. We showed these using the crackers and cream!

Today, we dived deeper into the layers of the earth and focused on the crust. We discovered that the crust is broken up into smaller pieces called tectonic plates. These tectonic plates are constantly moving but they move very slowly. We discussed how these plates used to be one and this was called Pangea but over around 350 million years it has moved and become what we know today. The 7 major tectonic plates are Pacific Plate, North American Plate, Eurasian Plate, African Plate, Antarctic Plate, Indo-Australian Plate, and South American Plate. 

Today, we used soft clay to show the different layers of the earth. We used the different colours to represent the different layers. The yellow represented the inner core, the orange represented the outer core, the red represented the mantle and the blue and green represented the crust. We were amazed when we cut them in half to see the sections.
