Lesson Plan for Primary 4 - Basic Science and Technology - Mixture + Physical Fitness + Virus

### Lesson Plan: Basic Science and Technology **Grade:** Primary 4 **Topic:** Mixture, Physical Fitness, Viruses **Duration:** 90 minutes #### Learning Objectives: 1. Understand what a mixture is and be able to provide examples. 2. Identify different components of physical fitness and the importance of each. 3. Explain what a virus is and how it can affect the human body. --- ### Lesson Outline **1. Introduction: (10 minutes)** - **Greeting and Roll Call:** Welcome students and take attendance. - **Overview of Lesson:** Briefly introduce the topics to be covered: Mixtures, Physical Fitness, and Viruses. - **Engage Students:** Ask students if they can think of examples of mixtures they encounter in daily life, ways they keep fit, and if they have heard of any common viruses. --- ### Segment 1: Mixtures (25 minutes) 1. **Definition of Mixtures: (5 minutes)** - Explain what a mixture is: a combination of two or more substances where each substance retains its own properties. - Provide examples: salt and water, sand and iron filings, fruit salad. 2. **Types of Mixtures: (5 minutes)** - Homogeneous Mixtures: Uniform composition, like salt water. - Heterogeneous Mixtures: Non-uniform composition, like a salad. 3. **Activity - Creating Mixtures: (10 minutes)** - Materials: Sand, salt, water, oil, spoons, and cups. - Students will create their own mixtures and try to separate them using tools provided. 4. **Discussion and Q&A: (5 minutes)** - Discuss which mixtures were easy to separate and why. Ask students if they can come up with more examples. --- ### Segment 2: Physical Fitness (25 minutes) 1. **Introduction to Physical Fitness: (5 minutes)** - Explain that physical fitness is the ability of the body to perform daily activities with energy and without fatigue. 2. **Components of Physical Fitness: (7 minutes)** - Cardiovascular Endurance: Running, swimming. - Muscle Strength: Lifting weights, push-ups. - Flexibility: Stretching, yoga. - Body Composition: The ratio of fat to lean muscle. 3. **Group Exercise Activity: (10 minutes)** - Warm-Up: Stretching exercises. - Quick Fitness Circuit: Include jumping jacks, push-ups, and running in place. 4. **Cool Down and Discussion: (3 minutes)** - Brief cool-down session. - Discuss how students felt during the exercise and the importance of staying active. --- ### Segment 3: Viruses (20 minutes) 1. **Introduction to Viruses: (5 minutes)** - Explain what a virus is: A tiny organism that can infect living cells and cause illness. 2. **How Viruses Spread: (5 minutes)** - Through the air (coughing, sneezing). - Through contact (touching surfaces with the virus). 3. **Preventing Virus Infections: (5 minutes)** - Hand washing. - Vaccination. - Proper hygiene. 4. **Quick Activity - Virus Simulation: (5 minutes)** - Use colored stickers to simulate how quickly a 'virus' can spread through interaction. - Discuss what practices can reduce the spread. --- ### Conclusion: (10 minutes) 1. **Recap:** - Quickly review what was learned about mixtures, physical fitness, and viruses. 2. **Interactive Q&A:** - Open floor for questions and encourage students to share what they found most interesting. 3. **Homework Assignment:** - Mixture: Find and list three examples of mixtures at home. - Physical Fitness: Write down a simple exercise plan they can follow during the week. - Virus: Draw and label how they keep germs away (handwashing, covering mouth when sneezing). 4. **Closing:** - Offer praise for participation and remind students to stay curious and active. --- ### Materials Needed: - Sand, salt, water, oil - Spoons, cups - Stickers for simulation - Mats for physical activities (optional) ### Assessment: - Participation in activities - Contributions to discussion - Completed homework assignment --- This lesson plan integrates hands-on activities, physical exercise, and health education, making it engaging and informative for Primary 4 students.
