Step 3
Exploring the Scientific Method
20 minutes
- Continue through the Mystery Solvers Slide Deck, explaining each step of the scientific method in detail.

- Facilitate a short class discussion or quick check for understanding after each step.
Step 4
Evidence Gathering Game (Activity)
15 minutes
- Introduce the Evidence Gathering Game activity.
- Divide students into small groups.
- Provide each group with the game instructions and any necessary materials.
- Circulate to assist groups and ensure they are applying the scientific method concepts.
Step 5
Famous Science Mysteries (Reading & Wrap-up)
5 minutes
- Distribute the Famous Science Mysteries reading.
- Explain that this reading provides examples of real-world scientific mysteries solved using similar methods.
- Assign the reading as homework or for independent reading time.
- Conclude the lesson by reiterating the importance of the scientific method and encouraging students to be 'scientific sleuths' in their own lives.

Slide Deck
Scientists: The Ultimate Detectives!
What do detectives do?
- Observe clues
- Ask questions
- Form ideas (hypotheses)
- Test their ideas
- Solve the case!
Guess what? Scientists do the exact same thing!
Greet students and introduce the theme. Ask them if they like mysteries or detective stories. Connect this to how scientists work.
The Scientific Method: Your Detective Toolkit
A step-by-step guide to solving problems and understanding the world around us.
It helps scientists:
- Organize their thoughts
- Conduct fair investigations
- Find reliable answers
Explain that the Scientific Method is like a detective's toolkit. Each step is a tool they use to solve a mystery (a scientific question).
Step 1: Ask a Question
Every great mystery starts with a question!
- What do you want to find out?
- The question should be testable.
Example: Why did the cookies burn?
Introduce the first step. Give a simple example, like 'Why does my plant look droopy?'
Step 2: Do Background Research
Before you investigate, see what's already known.
- Look for information in books, articles, or online.
- Talk to experts.
Example: What temperature do cookies usually bake at? How long?
Explain the importance of background research. If a detective doesn't know about fingerprints, they can't use them. Scientists need to know what's already known.
Step 3: Form a Hypothesis
Make an educated guess based on your research.
- It's a possible answer to your question.
- Often written as an "If... then..." statement.
Example: If the oven temperature was too high, then the cookies burned faster.
Define hypothesis. Emphasize it's an educated guess. Use an 'If... then...' statement.
Step 4: Conduct an Experiment
Test your hypothesis to see if your guess is correct.
- Design a fair test.
- Only change one thing at a time (this is called your variable).
- Collect data (observations, measurements).
Example: Bake two batches of cookies, one at the recommended temperature and one at a higher temperature.
Explain experimentation. Stress that it must be a fair test with only one thing changing (the variable). Use the cookie example.
Step 5: Analyze Your Data
Look at the information you collected from your experiment.
- What do your observations and measurements tell you?
- Organize your data (charts, graphs).
Example: Compare the baking time and appearance of the cookies from both batches.
Talk about analyzing data - what did the experiment show? Did the higher temperature cookies burn?
Step 6: Draw a Conclusion
What did you learn from your experiment?
- Was your hypothesis supported by the data?
- It's okay if your hypothesis wasn't correct – you still learned something!
Example: The cookies baked at the higher temperature burned, supporting the hypothesis.
Discuss drawing conclusions. Did the experiment support the hypothesis? If not, that's okay! It's still learning. Connect to the cookie example.
Step 7: Share Your Results
Let others know what you found!
- Write reports.
- Give presentations.
- This helps other scientists learn and continue solving mysteries.
Example: Share your cookie experiment findings with a baking blog!
Explain sharing results. Scientists don't work in secret! They share what they find so others can learn and build on their work.
Time to Be Scientific Sleuths!
Now it's your turn to put on your detective hats!
We're going to play the Evidence Gathering Game to practice using the scientific method.
Transition to the activity. Explain how the game will help them practice these steps.
Keep Asking Questions!
The world is full of mysteries waiting to be solved.
You have the toolkit to be a great scientific detective!
Conclude the slide deck. Remind students that science is all about curiosity and investigation.
Warm Up
Case File Kick-Off: Become a Detective!
Instructions: Imagine you are a detective called to solve a mystery. Read the scenario below and answer the questions. Your answers will help you think like a scientist!
The Mystery of the Vanishing Snack
When you left for school this morning, there was a delicious-looking apple on the kitchen counter. You come home, and the apple is GONE! There are some crumbs on the floor near where the apple was, and the back door is slightly ajar. Your dog, Sparky, is looking very innocent (maybe too innocent?).
-
Observation: What clues did you observe that something happened to the apple?
-
Question: What is the main question you want to answer about the vanished apple?
-
Hypothesis: Based on your observations, what is your educated guess about what happened to the apple? (Think "If... then...")
-
Experiment Idea: How would you test your hypothesis to find out if you're right? What steps would you take?
-
Conclusion: What kind of evidence would tell you that your hypothesis was correct? What if it wasn't correct?
Activity
Evidence Gathering Game: The Classroom Conundrum
Objective: To practice the steps of the scientific method by solving a classroom mystery!
Materials per group:
- One mystery object (provided by teacher - e.g., a strange rock, a plant with yellowing leaves, a deflated balloon)
- Observation sheet/notebook
- Pencil
Instructions: Your group is a team of scientific detectives. You have been given a mystery object. Your task is to use the scientific method to try and understand something about this object.
Your Detective Case File
Step 1: Ask a Question
Look closely at your mystery object. What is something you are curious about? What question could you ask about it that you could investigate?
Our Question:
Step 2: Do Background Research (Brainstorming & Initial Observations)
Discuss with your group what you already know about objects like this. What are some initial observations you can make? (Don't touch it yet, just look!)
Our Observations/Known Facts:
Step 3: Form a Hypothesis
Based on your question and initial observations, what is your educated guess (hypothesis) to answer your question? Remember the "If... then..." format.
Our Hypothesis:
Step 4: Conduct an Experiment (Planned Investigation)
How will you test your hypothesis? Describe the steps you will take. What will you measure or observe? What is the one thing you will change or focus on (your variable)?
Our Experiment Plan:
Step 5: Analyze Your Data
After performing your experiment (or imagining you did!), what do you think your results would look like? What data would you collect? How would you organize it?
Our Expected Data/Observations:
Table:
Step 6: Draw a Conclusion
Based on your expected data, what conclusion would you draw? Was your hypothesis supported? Why or why not? What did you learn?
Our Conclusion:
Step 7: Share Your Results (Group Discussion)
Prepare to share your mystery object, your question, your hypothesis, and your conclusion with the class. Be ready to explain your thinking!
