Overview

• Unit: Exploring the Wonders of Science
• Lesson Number: 7 of 20
• Duration: 60 minutes
• Class Size: 1 student
• Age Group: Year 11 (15-16 years old)
• National Curriculum Link:
  • Working scientifically: "asking questions and developing a line of enquiry based on observations of the real world, alongside prior knowledge and experience"
  • Practical skills: "planning, carrying out, analysing and evaluating practical investigations"
  • Scientific attitudes: "engagement with science including asking questions, evaluating evidence and considering scientific explanations"

Learning Objectives

By the end of the lesson, the student will be able to:

1. Outline the key steps of the scientific method: Ask Questions, Background Research, Hypothesis, Experiment, Data Collection, Analysis, Conclusion, and Communication.
2. Apply the scientific method to a real-world problem or investigation.
3. Explain how the scientific method ensures reliability, validity, and reproducibility in scientific investigations.

Success Criteria

• Student can accurately list and describe all the steps in the scientific method.
• Student formulates a hypothesis relevant to a practical scenario.
• Student designs a simple experiment incorporating control variables.
• Student explains how their findings could be validated or critiqued.
• Student reflects on the importance of using the scientific method in science.

---

Resources Required

• Whiteboard and markers
• Notebook or digital device for notes
• Printed worksheet with a real-world scenario
• Simple experimental materials (e.g., seeds, water, light source) or an imagined experiment setup
• Visual flowchart of the scientific method steps (prepared beforehand)

Lesson Breakdown

1. Introduction and Activation of Prior Knowledge (10 mins)

• Engage student with a quick question: "How do you think scientists answer questions or solve problems in the real world?"
• Discuss any prior ideas about investigations or experiments.
• Introduce the concept of the scientific method as a structured approach to answering scientific questions.
• Present a clear, colourful flowchart of the scientific method with the 7-8 key steps.

Teaching tip: Invite the student to annotate or rearrange printed cards of each step to encourage active participation and reinforce sequence memory.

2. Step-by-Step Exploration (20 mins)

• Deep dive into each stage:

  1. Ask a Question – Define a clear, testable question.
  2. Background Research – Importance of existing knowledge.
  3. Hypothesis – Make an informed prediction.
  4. Experimentation – Design a fair test and identify variables.
  5. Data Collection – Methods of recording observations.
  6. Analysis – Interpreting results with graphs/charts if applicable.
  7. Conclusion – Summarising findings relative to hypothesis.
  8. Communication – Sharing results with others.

• Discuss how reliability, reproducibility, and validity are addressed at each step to maintain scientific rigour.

Activity: Use an everyday question like "Does light affect plant growth?" and talk through each step as a scaffolded example.

3. Application Task - Real World Scenario (20 mins)

• Provide a simple, relatable scientific problem (e.g., testing different brands of paper towels for absorbency).

• Ask the student to:

  • Formulate a clear scientific question.
  • Propose a hypothesis.
  • Outline an experiment, including variables to control.
  • Describe how data will be collected and analysed.
  • Explain how a conclusion could be drawn.

• Encourage the student to write down or verbally present their experimental design and reasoning.

Extension idea: Discuss potential improvements or further questions that might arise, linking to critical thinking skills.

---

4. Plenary and Reflection (10 mins)

• Recap the lesson with the student summarising the scientific method steps in their own words.

• Ask reflective questions:

  • "Why is it important to control variables?"
  • "What happens if an experiment can’t be reproduced?"
  • "How might different scientists investigating the same question work together?"

• Use success criteria checklist for self-assessment and set a personalised target related to the next lessons in the unit.

---

Assessment

• Formative:
  • Observation of student participation during discussion and activities.
  • Review the written or verbal application task for accurate use of scientific method steps.
• Summative:
  • End-of-unit quiz or written assignment requiring explanation and application of the scientific method (to be administered later).

---

Differentiation and Personalisation

• One-to-one teaching allows the pace and depth to be tailored; extend with more complex variables or inquiry-based learning as appropriate.
• Use analogy and real-life examples connected to the student’s interests for deeper engagement.
• If the student struggles, scaffold with sentence starters or step cards.

---

Cross-Curricular Links

• English: Developing explanatory writing and argument formation skills through hypothesis and conclusion writing.
• Maths: Interpreting data, creating and analysing graphs.

---

Teacher Reflection Notes

• Ensure the student gains confidence in using the scientific method as a foundation for all future scientific investigation.
• Observe if the student connects this structured approach with practical experimentation already experienced.
• Consider incorporating digital tools (e.g., spreadsheet or graphing software) in future lessons for data analysis.
