| Question | Answer |
|---|---|
| Geologist | a scientist who studies the solid part of the Earth |
| landform | a feature of Earth's surface like a cliff, mountain, or a canyon |
| observation | something you notice using any of the 5 senses |
| evidence | information that supports an answer to a question |
| stable | staying mostly the same |
| How do landforms come? | Landforms come in many different shapes, sizes and colors |
| What are landforms made of? | Landforms are made of rocks |
| Can rock change? | Even though rock is hard, it can change |
| What is sand made of? | Sand is made of tiny pieces of rock |
| What does invesigating sand helps us learn? | Invesigating sand helps us learn how rock has changed |
| Can geologists always observe the changes happening? | Geologists cannot always observe the changes happening. Geologists make observations and visualize how changes happen. |
| What do scientists use to help them investigate things they cannot observe? | Scientists use models to help them investigate things they cannot observe. |
| What does a scientific explanation answer? | A scientific explanation answers a question, based on science ideas you have learned, shared with someone, and uses science words. |
| Explain how the flagpole got to the edge of the cliff. | The shape of the landform changed when water hit it causing pieces of rock to break off. |
| Valley | a landform shaped like a v that is often located between two hills or mountains |

| pumice | rock formed during volcanic eruptions |
| diagram | an illustration that shows how something works or what its parts are |
| model | something scientists make to help answer questions about the real world. They help simplify things. |
| Landforms seem stable which makes it hard to visualize water changing them. | |
| Water is very powerful as a liquid or solid. It is more powerful than any landform. | |
| Scientists make diagrams based on evidence from investigations, models and books to share their ideas. | |
| When we investigate why the cliff has changed, we are acting like geologists. | |
| Diagrams can be a type of model. | |
| The shape of a landform changes when water causes pieces of rock to break off and erosion causes water to wash away land. | |
| When scientists cant observe a situation because it happens over time, they visualize what may happen. |
