🔬 Part 1: Scientific Method Steps

1. Put the steps of the scientific method in the correct order by numbering them 1-6:

_____ Analyze data and draw conclusions

_____ Make an observation

_____ Conduct the experiment

_____ Form a hypothesis

_____ Ask a question

_____ Design an experiment

2. Which of the following is a testable hypothesis?

Plants are beautiful when they grow tall

If plants receive more sunlight, then they will grow taller

Plants should always be watered daily

Green plants are better than red plants

3. In an experiment testing how water affects seed germination, what is the independent variable?

The number of seeds that germinate

The amount of water given to the seeds

The type of soil used

The temperature of the room

4. What is a control group?

The group that receives the experimental treatment

The group that does not receive the experimental treatment

The variable being measured

The hypothesis being tested

🌱 Part 2: Applying the Scientific Method

5. Read this scenario: "Maria notices that some plants in her garden grow much taller than others, even though they are the same type of plant."

a) Write an observation based on this scenario:

b) Write a testable hypothesis that could explain Maria's observation:

6. Design a simple experiment to test your hypothesis from question 5b.

Independent variable: _________________________________

Dependent variable: ___________________________________

Control group: _______________________________________

What would you keep the same (controlled variables)?

💭 Part 3: Critical Thinking

7. Explain why forming a hypothesis is important in the scientific method. Give an example from today's class.

8. A student concludes that "music makes plants grow faster" after playing music to one plant for a week and seeing it grow 2 inches. List two problems with this experiment:

Problem 1: ________________________________________

Problem 2: ________________________________________

9. Why is it important for scientists to communicate their results to other scientists?
