**Grade Level:** 9th Grade
**Subject:** Science
**Topic:** Scientific Inquiry and Method
**Duration:** 90 minutes
---
#### **Objectives:**
1. Students will understand and describe the steps of the scientific method.
2. Students will differentiate between observation and inference.
3. Students will develop testable questions and hypotheses.
4. Students will apply the scientific method through hands-on activities.
#### **Materials:**
- Whiteboard and markers
- Projector and computer
- Printed worksheets on Scientific Inquiry and Method
- Laboratory equipment (e.g., beakers, thermometers, stopwatch, etc.)
- Sample experiment kits (e.g., vinegar and baking soda, seeds for planting, etc.)
- Chart paper and markers for group work
#### **Preparation:**
- Print necessary handouts and worksheets.
- Prepare the projector with slides on the scientific method.
- Set up sample experiment stations around the classroom.

### **Lesson Outline:**
#### **Introduction: (10 minutes)**
1. **Welcome and Attendance:** Greet students and take attendance.
2. **Hook/Engagement:**
- Show a short video clip demonstrating a fun scientific experiment.
- Discuss the importance of scientific inquiry in understanding the world.
#### **Direct Instruction: (20 minutes)**
1. **Explain the Scientific Method:**
- Present the steps of the scientific method using a mixture of lecture and slides:
1. Ask a Question
2. Conduct Background Research
3. Construct a Hypothesis
4. Test the Hypothesis by Conducting an Experiment
5. Analyze Data and Draw Conclusions
6. Communicate Results
- Provide real-world examples of how each step is used in scientific research.
2. **Observation vs. Inference:**
- Define and differentiate between observation (what you see) and inference (what you think based on what you see).
- Show examples and ask students to classify statements as either observations or inferences.
#### **Guided Practice: (20 minutes)**
1. **Worksheet Activity:**
- Distribute worksheets that contain various scenarios.
- In groups of three, students identify the steps of the scientific method in each scenario.
- Walk around the room to provide support and check for understanding.
2. **Class Discussion:**
- Discuss student answers and clarification of any misconceptions.
#### **Independent Practice: (30 minutes)**
1. **Hands-On Experiment:**
- Divide students into small groups (4-5 students per group).
- Assign each group a simple experiment (e.g., reacting baking soda with vinegar, growing seeds under different conditions).
- Students will:
1. Create a testable question.
2. Form a hypothesis.
3. Design and conduct the experiment.
4. Record observations and data.
5. Analyze the results and draw conclusions.
- Encourage students to follow the steps of the scientific method explicitly.
#### **Closure: (10 minutes)**
1. **Group Presentations:**
- Each group will present their experiment and findings to the class.
- Encourage students to discuss what they learned and any challenges they encountered.
2. **Recap and Homework:**
- Recap the day's lesson and emphasize the importance of each step in the scientific process.
- Assign homework: Students will choose a simple question to investigate using the scientific method and write a brief proposal outlining their plan.

### **Assessment:**
- **Formative Assessment:**
- Monitoring group discussions and worksheet completion.
- Observing hands-on experiments and group participation.
- **Summative Assessment:**
- Evaluation of group presentations.
- Reviewing homework proposals for understanding of the scientific method.
---
### **Extensions/Modifications:**
- **Extensions:**
- Advanced students can design more complex experiments that involve multiple variables.
- **Modifications:**
- Provide additional support and modified worksheets for students who need it.
- Use peer assistance and collaborative learning techniques to help struggling students.
---
### **Reflection:**
- After the lesson, evaluate what worked well and what could be improved.
- Collect feedback from students to understand their engagement and learning outcomes.
- Adjust future lessons based on student understanding and performance.
