## Lesson Plan: Earth’s Systems (Geology and Hydrology)
### Grade Level: 5th Grade
### Duration: 60 minutes
---
### Objectives:
By the end of the lesson, students will be able to:
1. Identify and describe Earth’s major systems: geosphere, hydrosphere, atmosphere, and biosphere.
2. Understand the basic components and processes of the geosphere and hydrosphere.
3. Explain how Earth's systems interact with one another.
### Materials:
- Whiteboard and markers
- Projector and screen
- Earth System posters or charts
- Rocks and mineral samples (if available)
- Water cycle diagram
- Interactive notebook or journal
- Pencils and colored pencils
- Internet access for videos
### Standards:
- Next Generation Science Standards (NGSS):
- 5-ESS2-1: Develop a model using an example to describe ways the geosphere, biosphere, hydrosphere, and/or atmosphere interact.
- 5-ESS2-2: Describe and graph the amounts and percentages of water and fresh water in various reservoirs to provide evidence about the distribution of water on Earth.
### Procedure:
#### Introduction (10 minutes):
1. **Engage**:
- Begin with a short video clip about Earth’s systems to grab students' attention. (Example: "Introduction to Earth's Systems" from National Geographic or a similar resource).
- After the video, ask students:
- "What are some of the Earth systems mentioned in the video?"
- "Can anyone describe what the geosphere and hydrosphere are?"
#### Direct Instruction (20 minutes):
2. **Explain**:
- Use a poster or whiteboard to introduce and define Earth's four systems: Geosphere, Hydrosphere, Atmosphere, and Biosphere.
- Focus specifically on the Geosphere and Hydrosphere:
- **Geosphere**: Explain that it includes rocks, minerals, mountains, and Earth's interior layers (core, mantle, crust).
- Show rock and mineral samples if available to give a tangible example.
- **Hydrosphere**: Describe that it consists of all water on Earth (oceans, rivers, lakes, glaciers, groundwater).
- Use a water cycle diagram to explain processes like evaporation, condensation, precipitation, and collection.
#### Guided Practice (15 minutes):
3. **Explore**:
- Break students into small groups and provide them with interactive notebooks or journals.
- Have each group create a mini-poster that includes:
- Definitions of Geosphere and Hydrosphere.
- Examples and diagrams illustrating these systems.
- Groups should present their poster briefly to the class.
#### Independent Practice (10 minutes):
4. **Elaborate**:
- Provide an activity sheet where students match parts of Earth (like mountains, rivers, etc.) to the correct Earth system.
- Include questions that require students to explain interactions (e.g., "How does rain affect the soil and rocks?").
#### Conclusion (5 minutes):
5. **Evaluate**:
- Recap the lesson by discussing how the Geosphere and Hydrosphere interact. Ask questions like:
- “Can anyone give an example of how water (hydrosphere) affects rocks and soil (geosphere)?”
- “What happens to the rainwater that does not go into the ocean?”
#### Extension (Optional):
- Assign a homework project where students create a diorama or model showing the interaction between the Geosphere and Hydrosphere.
- Provide a list of online resources or books for further reading.
### Assessment:
- Monitor group activities and check journals for understanding during the Elaborate phase.
- Collect and review the completed activity sheets for accuracy and comprehension.
- Evaluate participation and presentations for engagement and understanding of the material.
### Differentiation:
- **For advanced students**: Assign additional research on specific interactions between Earth’s systems, such as how volcanic eruptions (geosphere) can affect water bodies (hydrosphere) and weather patterns (atmosphere).
- **For struggling students**: Pair them with peers for collaborative learning, provide guided notes, and use more visual aids to support understanding.
### Resources:
- National Geographic Kids videos and articles
- US Geological Survey (USGS) resources for kids
- Interactive water cycle games and activities (e.g., Water Cycle from the EPA)
