**Lesson Plan: Basic Science and Technology for Primary 4**
**Topic:** Measurement + Food and Nutrition + Coding
**Grade Level:** Primary 4
**Duration:** 60 minutes
**Goals:**
1. To understand basic principles of measurement.
2. To learn about the importance of nutrition in our daily diet.
3. To grasp simple coding concepts.
**Objectives:**
1. Students will be able to measure objects using standard and non-standard units.
2. Students will recognize different food groups and understand their nutritional importance.
3. Students will learn basic coding skills using a simple, age-appropriate platform.
**Materials:**
- Rulers, tape measures, measuring cups, and spoons
- Various fruits and vegetables
- Paper plates, markers, and stickers
- Laptops/tablets with internet access
- Scratch Jr. or an equivalent coding platform
**Introduction (10 minutes):**
1. **Hook:** Begin with a quick story about a chef who needs help measuring ingredients, choosing nutritious foods, and programming a kitchen robot. Explain that today's lesson will teach them these skills.
2. **Warm-Up:** Discuss what measurement, nutrition, and coding mean. Allow a few students to share what they know about each topic.
**Part 1: Measurement (15 minutes):**
1. **Activity:**
- Split the students into small groups.
- Give each group rulers, tape measures, measuring cups, and spoons.
- Have them measure different classroom objects (e.g., desk, book, pencil) using both standard (rulers, tape measures) and non-standard units (hand spans, blocks).
- Rotate groups to measure quantities of water or rice using measuring cups and spoons.
2. **Discussion:**
- Bring students back together.
- Discuss why measurements are important and how different units are used in various contexts (cooking, construction, science).
**Part 2: Food and Nutrition (15 minutes):**
1. **Activity:**
- Display various fruits and vegetables.
- Provide paper plates and markers.
- Have students create a balanced meal plate by drawing or sticking pictures of food onto their paper plates. Encourage them to include items from different food groups: fruits, vegetables, grains, proteins, and dairy.
2. **Discussion:**
- Explain the importance of each food group.
- Discuss what makes a balanced diet and why it's important for health and energy.
**Part 3: Coding (15 minutes):**
1. **Activity:**
- Introduce students to Scratch Jr. or a similar age-appropriate coding platform.
- Demonstrate how to create a simple project, such as programming a character to move or speak.
- Allow students to explore the platform and try a basic coding exercise (e.g., make a character move across the screen).
2. **Discussion:**
- Talk about how coding can be used in everyday life, like programming robots or creating games.
- Highlight the importance of logical thinking and problem-solving in coding.
**Conclusion (5 minutes):**
1. **Review:** Summarize key points from measurement, food and nutrition, and coding.
2. **Q&A:** Allow students to ask any remaining questions and share something new they learned.
3. **Assignment:** Give a simple homework assignment, such as measuring three items at home, creating a meal plan for a day, and drawing a simple code they would like to write.
**Evaluation:**
- Observe students' participation during group activities.
- Check their paper plates for an understanding of a balanced diet.
- Review any coding work done during the lesson.
**Notes:**
- Adjust time allotted to each section based on class dynamics.
- Ensure all students understand each part before moving on to the next.
