### Lesson Plan: Properties of Materials
#### Grade: 5
#### Subject: Science
#### Topic: Properties of Materials
#### Duration: 60 minutes
---
#### Objectives:
1. Students will be able to identify different properties of materials.
2. Students will understand how the properties of materials determine their use.
3. Students will conduct simple experiments to test the properties of materials.
---
#### Materials Needed:
- Samples of various materials (wood, metal, plastic, glass, fabric, rubber)
- Magnifying glasses
- Water, saltwater, oil
- Ice cubes
- Magnets
- Worksheets
- Projector/Interactive whiteboard
- Chart paper and markers
---
#### Standards:
- NGSS 5-PS1-3: Make observations and measurements to identify materials based on their properties.
- NGSS 5-PS1-4: Conduct an investigation to determine whether the mixing of two or more substances results in new substances.

#### Introduction (10 minutes):
1. **Greeting and Attendance** (2 minutes)
2. **Hook Activity** (3 minutes): Show a short video clip that demonstrates everyday uses of various materials (e.g., building a house, creating clothes, making cookware).
3. **Class Discussion** (5 minutes): Ask students what they noticed about the materials used in the video. Discuss why different materials are chosen for different tasks. Write key vocabulary on the board (e.g., hard, soft, flexible, waterproof, magnetic).
---
#### Instruction (15 minutes):
1. **Presentation** (10 minutes): Use the projector/interactive whiteboard to show slides that introduce key concepts about material properties (e.g., hardness, flexibility, buoyancy, magnetism, thermal conductivity).
- Provide examples for each property.
- Discuss how scientists and engineers choose materials based on these properties.
2. **Teacher Demonstration** (5 minutes): Perform a live demonstration where you test some materials for one or two properties, such as hardness (using a scratch test) and buoyancy (placing an object in water).
---
#### Activity (20 minutes):
1. **Introduction to Activity** (5 minutes):
- Explain that students will be scientists testing different properties of materials.
- Review safety guidelines and procedures.
2. **Group Work** (15 minutes):
- Divide students into small groups.
- Provide each group with a set of materials and a worksheet.
- Instruct students to test their materials for different properties: hardness, flexibility, buoyancy, and magnetism.
- Each group should record their observations and results on the worksheet.
---
#### Conclusion (10 minutes):
1. **Group Presentations** (5 minutes): Each group presents their findings to the class.
2. **Class Discussion** (3 minutes): Discuss how their findings compare to the initial predictions and share any surprising results.
3. **Wrap-Up** (2 minutes): Summarize the lesson, emphasizing the importance of understanding material properties in everyday life and scientific applications. Answer any final questions.

#### Assessment:
1. **Formative Assessment**:
- Observations during group activity and participation in class discussions.
2. **Summative Assessment**:
- Worksheet completion and accuracy.
- Group presentation clarity and understanding of material properties.
---
#### Homework:
1. Students will complete a worksheet where they list 5 objects at home and identify the materials they are made of, explaining why those materials are suitable for those objects.
---
#### Extensions:
- Advanced students can research one material in detail and present how its properties make it useful for specific applications.
- Arrange a visit from a materials engineer or scientist to talk about their work and how they use knowledge of material properties in their field.
---
#### Differentiation:
- Provide visual aids and hands-on materials for students who benefit from tactile learning.
- Pair ELL students with bilingual peers or use translation tools to assist with new vocabulary.
---
#### Reflection:
- After the lesson, reflect on what went well and what could be improved for future lessons. Collect feedback from students to understand their level of engagement and comprehension. Adjust the plans for upcoming lessons based on these reflections.
