National Curriculum Links

This lesson supports the following key stage 4 scientific framework from the National Curriculum for England:

• Developing scientific attitudes: Recognise the importance of evidence in developing scientific explanations (KS4 Programme of Study – Scientific enquiry).
• Asking questions and defining lines of enquiry: Formulate scientific questions and hypotheses for investigation.
• Planning and carrying out investigations: Understand the process of scientific enquiry including observation, hypothesising, experimentation, and conclusion.
• Communicating: Communicate scientific ideas clearly using appropriate scientific language.

---

Learning Objectives

By the end of the lesson, the student will:

1. Understand and articulate the main steps of the scientific inquiry process (question, hypothesis, observation, experiment, conclusion).
2. Formulate a scientific question based on a simple scenario.
3. Create a testable hypothesis linked to the question.
4. Appreciate the role of careful observation in science.

---

Success Criteria

• Accurately describe the sequence of scientific inquiry steps.
• Formulate a clear, specific scientific question.
• Write a hypothesis that is testable and linked to the question.
• Demonstrate reflective observation skills in an enquiry context.

---

Resources Needed

• Whiteboard and marker (or notebook if online)
• Prepared prompt cards with simple scientific scenarios (e.g., “Does sunlight affect plant growth?”)
• Observation worksheet template
• Scientific inquiry flowchart handout

Lesson Structure

1. Starter Activity (10 minutes)

Objective: Activate prior knowledge about science and introduce inquiry

• Begin with a quick warm-up discussion: “What do scientists do when they want to learn something new?”
• Prompt with questions: “How do you think scientists find answers to questions? What comes first – the question or the investigation?”
• Write student's thoughts on the board or notebook to visualise thinking.
• Introduce the term scientific inquiry and explain it as the process scientists follow to learn about the world.

2. Explanation & Modelling (15 minutes)

Objective: Explain and model the steps of scientific inquiry

• Present a simple flowchart of the 5 key steps:
  1. Asking a Question
  2. Forming a Hypothesis
  3. Planning and Conducting an Investigation
  4. Making Observations and Recording Data
  5. Drawing Conclusions
• Walk through a fun example together, e.g., “Does the colour of light affect plant growth?”
  • Question: What is our scientific question here?
  • Hypothesis: Formulate a testable prediction like “If plants are grown under red light, then they will grow faster than those under blue light.”
  • Observation: What would you look out for during the experiment?
• Use visual aids or draw simple diagrams to connect each step.

3. Guided Practice (15 minutes)

Objective: Practice formulating scientific questions and hypotheses

• Present 2-3 prompt cards with familiar, everyday science questions (e.g., “Does temperature affect how quickly ice melts?”).
• For each prompt:
  • Ask the student to identify the scientific question(s) present.
  • Guide them to frame a testable hypothesis for one prompt of their choice.
• Write the question and hypothesis on a worksheet or in a notebook.
• Discuss how the hypothesis is specific and measurable.

---

4. Observation Activity (10 minutes)

Objective: Emphasise the importance of careful observation

• Provide a short video clip or live observation of a simple phenomenon (e.g., water droplets on a window or a chemical reaction like vinegar and bicarbonate).
• Ask the student to make detailed observations and record these on the worksheet.
• Discuss why accurate observations are crucial before forming conclusions.

---

5. Review & Reflection (10 minutes)

Objective: Consolidate learning and self-assessment

• Recap the 5 steps of scientific inquiry using the flowchart.
• Ask the student to explain each step in their own words.
• Review their formulated question and hypothesis to check alignment.
• Use these prompt questions for reflection:
  • “Can you describe what comes first in the scientific inquiry process?”
  • “Why is it important to make careful observations?”
  • “What makes a good hypothesis?”
• Encourage the student to self-assess against the success criteria and note any questions or challenges.

---

Differentiation & Extension

• Since this is a one-to-one setting, tailor questions and examples to the student’s interests to boost engagement.
• For stretch, challenge the student to consider variables they would control in the investigation and how they could collect data.

---

Assessment

• Formative assessment through responses during discussion and worksheet completion.
• Evaluate the clarity and testability of the student’s question and hypothesis.
• Observation activity worksheet to assess detail and scientific language used in recording.

---

Homework / Follow-up

• Ask the student to observe something in their home environment (e.g., plant growth, water boiling) over the next few days and write down questions or hypotheses that arise.
• Prepare to discuss their observations and questions in the next lesson, building the continuity of scientific inquiry learning.

---

Teacher’s Notes

• Emphasise scientific curiosity and keep the session interactive despite the one-student class size.
• Use real-world examples familiar to the student to highlight the relevance of the inquiry process.
• Keep language clear and accessible, but introduce key scientific vocabulary such as ‘hypothesis,’ ‘variables,’ ‘observation,’ and ‘conclusion.’
