STEM project Earth and space sciences SURFACE CHANGES The problem Project brief FORM THE LANDFORMS You are a junior geologist who needs to create a video for schoolchildren that demonstrates how erosion and weathering changes and shapes landforms and rocks. The task Create a scene with landforms made from sand and gelatin, and film what happens to the landforms and landscape as water weathers away at it and erodes the sand. Things to consider • You must work in groups of 2–3 students. • You must include at least four landforms in your scene. • The landforms must be made from a gelatine/sand mixture, using the recipe provided. You can choose or create your own molds depending on the shape or landform you are trying to achieve. You can add other features like trees or plants made from other materials. • You need to film a video and add a voice over explaining what happens when water weathers and erodes rock. The keywords erosion, weathering and landforms must be used. • Add music or sound effects to your video. • You will need to measure the height and width of your landforms before and after weathering and erosion and record the information in a table using a computer. You will then add the table to your video and explain what the data represents. • The video should be 3–4 minutes long. ©R.I.C.

Earth and space sciences SURFACE CHANGES STEM project Investigate Revise weathering and erosion and the difference between them. Watch a video which shows them in action by scanning this QR code or typing into a web browser. Revise how different landforms are formed over time, and the kind of shapes you will need to recreate. Explore iMovie ® or a similar application, and look at sound effect features and how to add voice overs. Design, plan and manage Draw a plan of how your scene will look and the four landforms you will include. Write a plan for the information you will include in your voice over for the video, being sure to include the keywords erosion, weathering and landforms. Write a list of materials and equipment you will need and gather them together. Create Make the gelatine/soil mixture, following the recipe. Make or find the molds you want to use. Project steps Pour the gelatine/soil mixture into the molds and leave in the fridge to set. Create your scene, by placing your landforms and other features into a large tray or container that has sides on it. Measure the height and width of each landform and record the information in a table. Pour warm water on your landforms, as if it were raining, and film the video showing what happens. Evaluate and refine Do your landforms look like the right shape and size? Do you need to add anything else to make the scene look better? Did the water weather/erode the landforms enough or do you need to use warmer water or a different tray? ©R.I.C. Publications Low Resolution Images Display Copy Communicate Add your voice over to the video, explaining how you demonstrated weathering and erosion, and add sound effects or music. Remeasure the height and width of each landform and add a digital version of the table of measurements, from before and after, to the end of your video. Explain what the results represent. R.I.C.
