Scientific Inquiry Basics

Overview

This 45-minute introductory lesson launches the "Exploring Science Connections" unit, focusing on the foundational skills of scientific inquiry as outlined in the British Columbia Science Curriculum for Grade 7. Students will understand the purpose and steps of the scientific method, practice developing investigable questions, and create hypotheses. This builds critical thinking and inquiry skills, preparing them to engage in meaningful, hands-on science investigations throughout the unit.

Curriculum Connections

Curricular Competencies:

• Demonstrate curiosity and a willingness to engage in scientific inquiry (Inquiry skills)
• Question and predict based on prior knowledge and on an initial exploration (Questioning and predicting)
• Plan and conduct simple investigations (Planning and conducting)
• Communicate ideas, findings, and solutions clearly and fairly (Communicating)

Big Ideas:

• Science involves developing and using models to explain and understand the natural world
• Curiosity, inquiry, and scepticism lead to scientific discovery and understanding

Content:

• Scientific inquiry and investigation methods
• Formulating questions, hypotheses, and experimental planning

Reference: BC Science Curriculum, Grade 7, "Science inquiry and skills" cluster

Learning Objectives

By the end of this lesson, students will be able to:

1. Define and explain the scientific method and its importance in science.
2. Formulate clear, investigable scientific questions based on observations.
3. Construct testable hypotheses linked to their questions.
4. Design simple experimental procedures to explore their hypotheses.

Materials Required

• Whiteboard and markers
• Chart paper and coloured markers
• Student notebooks
• Printed Scientific Method flowchart (simplified)
• Small everyday objects (e.g., paper clips, marbles, rubber bands) for examples

Lesson Structure

1. Introduction & Engagement (8 minutes)

• Greet students and explain the lesson focus: understanding how scientists investigate the world.
• Start with a provocative question on the board: "How do you figure out why something works the way it does?"
• Brief whole-class brainstorm: What do scientists do to answer questions?
• Introduce The Scientific Method as the "investigation recipe" scientists use. Show simple flowchart steps: Question, Hypothesis, Experiment, Observation, Conclusion.

2. Explicit Teaching (10 minutes)

• Briefly explain and describe each step of the scientific method using relatable examples (e.g., Why does a rubber band stretch? What happens if you drop objects of different sizes?).
• Emphasize that scientific questions must be clear, specific, and testable.
• Discuss what a hypothesis is: a prediction or educated guess that can be tested.
• Model writing a question and hypothesis as a class on the whiteboard using an everyday example.

3. Guided Practice (15 minutes)

• Divide students into pairs (9 pairs total). Give each pair a simple everyday object (e.g., paper clips and magnets).
• Task: In their pairs, students observe their objects and come up with:
  a) One clear, testable scientific question about the object.
  b) One hypothesis predicting the answer.
• Circulate and support pairs, prompting clearer questions and hypotheses where needed.
• Each pair writes their question and hypothesis on chart paper.

4. Sharing & Discussion (7 minutes)

• Pairs stick chart paper on the wall and briefly explain their questions/hypotheses to the class.
• Facilitate a class discussion highlighting what makes questions good or vague, and how hypotheses relate to questions.
• Reinforce the importance of curiosity and testing ideas to build knowledge.

5. Wrap-Up & Assessment (5 minutes)

• Recap key points orally: why inquiry and the scientific method matter in science.
• Exit ticket (individual, in notebooks): Write down one question you still have about science and one hypothesis you could test related to it.
• Collect exit tickets to assess understanding and guide Lesson 2 planning.

Differentiation Strategies

• Provide sentence starters or question stems for students needing extra support (e.g., I wonder if..., My hypothesis is... because...).
• Encourage advanced pairs to develop more complex hypotheses or design brief experimental steps.
• Use visual flowcharts and examples for students needing concrete representations of abstract ideas.

---

Teacher Reflection Prompts

• Were students able to create testable questions and hypotheses independently?
• What misconceptions about scientific inquiry appeared?
• How engaged were students during group collaboration and sharing?
• Which questioning or modelling strategies were most effective?
• What modifications could support students struggling with these concepts?

This well-rounded, active lesson aligns tightly with BC Science curricular competencies and big ideas, balancing direct instruction with hands-on practice and collaborative learning. It sets a rich foundation for students' scientific inquiry skills in the unit ahead.
