### Year 3 Science Lesson Plan: Forces and Magnets
**Lesson Topic:** Forces and Magnets
**Lesson Duration:** 60 minutes
**Age Group:** Year 3 (Ages 7-8)
#### Lesson Objectives:
By the end of this lesson, students should be able to:
1. Understand what a force is and how it can move objects.
2. Differentiate between magnetic and non-magnetic materials.
3. Understand how magnets attract and repel each other.
4. Conduct simple experiments with magnets and record their observations.
#### Key Vocabulary:
- Force
- Push
- Pull
- Magnetic
- Non-magnetic
- Attract
- Repel
- Magnet
### Lesson Structure:
#### 1. Introduction (10 minutes)
- **Hook Activity:** Start with a short and interactive demonstration using a magnet and various objects (paperclips, plastic, coin, etc.). Ask students to predict which objects will be attracted to the magnet and provide a brief explanation afterwards.
- **Objective Outline:** Explain the lesson objectives to the students and introduce the main concepts of forces and magnets.
#### 2. Explanation and Exploration (15 minutes)
- **Explain Forces:**
- Discuss the concept of a force in simple terms: a push or a pull that can make things move, stop, or change direction.
- Give everyday examples of forces (e.g., kicking a ball, opening a door).
- **Introduce Magnets:**
- Explain what magnets are and how they work.
- Discuss the properties of magnets, including magnetic poles (North and South) and how opposite poles attract and like poles repel.
#### 3. Hands-on Activity: Sorting Magnetic and Non-Magnetic Objects (15 minutes)
- **Group Work:**
- Divide the students into small groups and give each group a selection of objects (some magnetic and some non-magnetic), along with magnets.
- Instruct students to test each object to see if it is attracted to the magnet and sort the objects into two categories: Magnetic and Non-Magnetic.
- **Recording Results:**
- Provide students with a worksheet where they can list the objects and classify them as magnetic or non-magnetic.
#### 4. Experiment: Magnetic Forces (15 minutes)
- **Experiment 1: Attraction and Repulsion:**
- Give each student a pair of bar magnets.
- Demonstrate how opposite poles attract and like poles repel.
- Ask students to create a simple recording sheet to document their observations (e.g., which pairs of poles attract and which repel).
- **Experiment 2: Magnetic Field Lines (Optional, if time permits):**
- Place a bar magnet under a sheet of paper and sprinkle iron filings on top. Observe how the filings align along the magnetic field lines.
- Explain that this shows the invisible magnetic force around the magnet.
#### 5. Plenary and Review (5 minutes)
- **Discussion:**
- Ask students to share their findings from the activities.
- Reiterate the key points of the lesson, focusing on the concepts of forces, magnetic and non-magnetic materials, and the properties of magnets.
- **Q&A:**
- Allow time for questions and clarify any misconceptions.
#### Resources Needed:
- Magnets (bar magnets, horseshoe magnets, etc.)
- Assorted objects (paperclips, coins, plastic items, rubber items, etc.)
- Iron filings (for optional experiment)
- Sheets of paper
- Worksheets for recording observations
### Assessment:
- **Formative Assessment:**
- Monitor group activities and discussions to assess students' understanding.
- Review worksheets to check if students correctly identified magnetic and non-magnetic materials.
- **Summative Assessment:**
- A short quiz or a simple homework task on forces and magnets to evaluate students' grasp of the lesson content.
