Lesson Title: Scientific Method Lesson Plan (Grades 7–9)

Looking for an interactive Scientific Method lesson plan that brings real scientific thinking to life? This engaging classroom activity uses Goosechase to help students explore how hypotheses, variables, and experiments work through teamwork, data collection, and hands-on investigation.

Interactive Scientific Method Lesson Plan Overview

Science isn’t just lab coats and bubbling beakers, it’s the process behind every discovery, invention, and “why does that happen?” moment in our world. The Scientific Method is the engine that drives curiosity into real understanding.

In this interactive lesson, students dive into the scientific process through hands-on investigations, real-world examples, and a Goosechase scavenger hunt that transforms abstract steps into engaging, practical challenges. Whether they’re forming hypotheses, identifying variables, or testing ideas through mini-experiments, students will walk away with a clearer grasp of how scientists think, and how they can use those same skills to make sense of the world around them.

Grade: 7 - 9

Subject: Science (General Science, Life Science, Physical Science)

Learning Objectives for Introduction to Scientific Method Lesson:

• By the end of this lesson, students will:
  • Identify and explain the steps of the Scientific Method.
  • Formulate a clear hypothesis based on observations.
  • Distinguish independent, dependent, and controlled variables.
  • Conduct a simple experiment and record accurate qualitative and quantitative data.
  • Analyze results and draw evidence-based conclusions.
  • Reflect on errors, improvements, and the importance of repeatability in scientific investigations.

Materials for You Scientific Method Classroom Activity

• Mobile devices with the Goosechase app downloaded (one per team).
• List of Missions (created beforehand in the Goosechase app)
• Whiteboard or digital presentation tools
• Student notebooks or lab sheets
• Simple experiment supplies (teacher choice, e.g., paper airplanes, plant seeds, reaction materials, ramps and balls, etc.)
• Measuring tools (stopwatches, rulers, scales)

Preparation for the Goosechase Scientific Method Experience:

• Create an Experience on the Goosechase app with a series of Missions focussed on the scientific method.
• Develop Missions that require students to demonstrate their understanding of what they have learned. Example Missions:
  • Observation Station: Take a photo of something unusual in the classroom or outdoors and write one scientific question about it.
  • Hypothesis Builder: Submit a short video stating a hypothesis for a simple classroom challenge (e.g., “Which ball will bounce highest?”).
  • Identify the Variables: Upload a written list of independent, dependent, and controlled variables for a teacher-given scenario.
  • Procedure Planner: Record a voice message describing a clear, step-by-step experiment procedure.
  • Collect the Data: Share a screenshot or photo of a data table based on a quick measurement task.
  • Analyze & Conclude: Submit a short written or video conclusion based on your data.
  • Communicate Results: Create a 10-second “scientist announcement” video summarizing the findings.
  • Find Example Missions in the Goosechase Templates below

• Adapt the difficulty of the Missions to your students' proficiency levels to keep the activity inclusive and engaging for everyone.
• Prepare hints or resources that might help students solve the Missions if needed.
• Run your Experience during one class periods or longer
• Divide students into teams and assign each team a mobile device with the app, or have students complete the scavenger hunt individually.
• App Set-Up 
  • Dedicate time to ensuring all students have the Goosechase app downloaded and joined to the Experience to avoid any tech issues.

Interactive Scientific Method Lesson Plan Overview

• Warm Up: 
  • Display a puzzling image or short demo (e.g., a balloon that won’t pop when pressed against a skewer).
  • Ask students: “How could we figure out why this happens scientifically?
• Introduction to the Scientific Method
  • Briefly discuss each step:
    • Observation
    • Question
    • Hypothesis
    • Experiment
    • Data Collection
    • Analysis
    • Conclusion
    • Communicating Results
  • Emphasize keywords: variables, data, prediction, procedure, evidence.
• Guided Practice – Sample Investigation
  • Models an investigation for students to watch (e.g., Does the shape of a paper airplane affect how far it flies?)
  • Students then help to identify:
    • Hypothesis
    • Variables
    • Procedure
    • Measurement strategy
• Student Mini-Experiment
  • Students work in small groups to conduct a simple structured experiment selected by the teacher
  • Students document: observations, hypothesis, method, data table, and conclusions.
• Student Mini-Experiment Wrap-Up
  • Groups present quick findings.
  • Class discusses: What made the experiment fair? What would you change?
• Goosechase Scientific Method Experience
  • Read through Missions with students, emphasizing the importance of evidence and analysis in their responses.
  • Monitor progress and provide assistance as necessary.
  • If working in teams, encourage them to strategize and collaborate to solve the Missions.
  • Sit back and enjoy watching your students collaborate and demonstrate their learning.
• Debrief and Reflection 
  • Review the activity, discussing which missions were the most challenging or fun.
  • Discuss how teams collaborated and solved problems together.
  • What new connections did you make between the concepts?
  • Optionally, award prizes to the team(s) with the highest score.

Assessments & Extensions

Optional Post-Experience Activities:

• Scientific Method Reflection
  • Students analyze a real-world scenario (news article, online video) and identify where the Scientific Method is used.
• Experiment Proposal
  • Students design an experiment on paper including hypothesis, variables, and procedure.
• Vocabulary Creation
  • Build a glossary of scientific keywords with examples.
• Mini Research Project
  • Small teams create a poster explaining each step of the Scientific Method using examples from class.
• Peer Experiment Redesign
  • Groups trade lab sheets and suggest improvements to each other’s experimental design.
• Data Comparison Report
  • Students compare class-wide data and discuss inconsistencies or sources of error.

Assessment and Reflection: Evaluating Understanding of the Scientific Method

• Teachers can assess student understanding through:
  • Completed lab sheets or digital lab reports
  • Assessment of any post-lesson assignments.
  • Observation of group discussions and experiment processes
  • Goosechase mission submissions and engagement
  • Vocabulary quizzes or exit tickets
