🔬 Part 1: The Scientific Method

1. Put the steps of the scientific method in the correct order by numbering them 1-5:

Record results

Ask a question

Analyse and conclude

Make a hypothesis

Plan and perform an experiment

2. What is a hypothesis?

A proven fact

An educated guess that can be tested

The final result of an experiment

A type of scientific equipment

🧪 Part 2: Variables in Experiments

3. Match each type of variable with its correct definition:

1. Independent variable

2. Dependent variable

3. Control variables

A. What you measure or observe

B. What you change on purpose

C. What you keep the same

4. For our Alka-Seltzer experiment, identify the variables:

Independent variable (what we changed): ________________________

Dependent variable (what we measured): ________________________

Control variables (what we kept the same):

📊 Part 3: Our Experiment Results

5. Write your hypothesis for the Alka-Seltzer experiment:

I think that ________________________________________________

because ___________________________________________________

6. Record your experimental results in the table below:

7. What pattern did you observe in the class results?

Hot water made the tablet dissolve faster

Cold water made the tablet dissolve faster

Temperature made no difference

The results were too varied to see a pattern

8. Was your hypothesis supported by the results? Explain your answer:

🌍 Part 4: Science in the Real World

9. Which of these real-world examples use the scientific method? (Check all that apply)

Testing new medicines

Studying climate change

Developing space rockets

Creating new mobile phone apps

Investigating how plants grow

10. Why is it important for scientists to repeat experiments?

To make sure they get the same results every time

To check their results are reliable and not just luck

Because they enjoy doing experiments

To use up all their equipment

11. Suggest one improvement we could make to our Alka-Seltzer experiment:

💭 Part 5: Reflection

12. What is your key takeaway from this lesson?

13. Write one question you still have about how science works:

14. Design your own scientific investigation! Choose something you're curious about and fill in the blanks:

Question: How does _____________ affect _____________?

Hypothesis: I think that ________________________________

What I would change: ________________________________

What I would measure: ______________________________

What I would keep the same: __________________________
