### Lesson Plan: Forces and Magnets
**Grade Level:** 3
**Subject:** Science
**Duration:** 60 minutes
**Topic:** Forces and Magnets
---
#### Objectives:
1. **Understand** the concept of force and explore different types of forces.
2. **Identify** and **classify** materials that are magnetic and non-magnetic.
3. **Describe** how magnets attract and repel.
4. **Conduct** simple experiments to demonstrate magnetic forces.
---
#### Materials:
- Magnets (bar magnets and horseshoe magnets)
- Various objects (paper clips, plastic toys, coins, wooden pieces, etc.)
- Chart paper and markers
- Iron filings
- Paper and pencils for note-taking
- Interactive whiteboard or projector
- Videos/animations explaining magnetic fields (optional)
---
#### Lesson Outline:
1. **Introduction (10 minutes)**
- Begin with a brief discussion on what students already know about forces. Ask questions like:
- What is a force?
- Can you give examples of forces you see or use every day?
- Introduce magnets and explain that they create a force called magnetism.
2. **Explanation and Demonstration (15 minutes)**
- Explain the types of forces: push and pull.
- Introduce magnetic and non-magnetic materials. Show examples using different objects.
- Demonstrate how magnets attract magnetic materials (like paper clips) and do not attract non-magnetic materials (like plastic toys).
- Use a chart to classify objects as magnetic or non-magnetic based on the demonstrations.
3. **Interactive Experiment (20 minutes)**
- Hand out magnets and a variety of objects to small groups of students.
- Ask students to test each object to see if it is magnetic or not.
- Have students record their observations in a table on a provided worksheet.
- Discuss the results and ask:
- Which objects were magnetic?
- Which objects were non-magnetic?
- Did any results surprise you?
4. **Activity: Create and Observe Magnetic Fields (10 minutes)**
- Place a magnet under a sheet of paper and sprinkle iron filings on top.
- Gently tap the paper to spread out the filings and reveal the magnetic field lines.
- Discuss what they see and explain how magnetic fields work.
5. **Assessment (5 minutes)**
- Quick quiz: Provide a list of objects and ask students to label them as magnetic or non-magnetic.
- Ask students to draw a picture of two magnets showing either attraction or repulsion.
6. **Wrap-Up and Review (5 minutes)**
- Recap the key points of the lesson.
- Ask students to share one new thing they learned today.
- Provide a take-home worksheet for further practice, if desired.

#### Differentiation:
- **For Students Needing Extra Support:** Pair them with a buddy during group activities and provide step-by-step instructions.
- **For Advanced Students:** Challenge them to find creative ways to demonstrate magnetic force, such as creating simple magnetic toys or games.
---
#### Homework:
- Find three objects at home that are magnetic and three that are non-magnetic. Write them down and bring the list to the next class.
- Optional: Draw a picture showing two everyday uses of magnets.
---
#### Reflection:
- Assess student engagement and understanding through participation and the quiz.
- Note any concepts that need revisiting or further clarification.
- Gather feedback from students on what they enjoyed and found challenging to inform future lesson planning.
