🧠 1. What Is the Scientific Method?
The scientific method is a step-by-step process that scientists use to study the world, ask questions, run experiments, and draw conclusions based on evidence.
It helps explain how and why things happen in nature.
📚 2. Steps of the Scientific Method
1. Ask a Question or Identify a Problem
-
Why do leaves turn yellow?
-
Why does ice melt?
2. Make Observations and Gather Information
-
Carefully observe what’s happening.
-
Research and collect facts from reliable sources.
3. Form a Hypothesis
A hypothesis is an educated guess or prediction that can be tested.
🔹 Example: “If a plant doesn’t get water, it will dry out.”
4. Conduct an Experiment
-
Design a test to check the hypothesis.
-
Control all variables except the one being tested.
5. Analyze the Results
-
Write down what happens during the experiment.
-
Use charts, graphs, or tables if needed.
-
Compare the result to the hypothesis.
6. Draw a Conclusion
-
Does the experiment support your hypothesis?
-
If not, change or reject it and try again.
7. Share the Results
-
Scientists publish results in journals, presentations, or online platforms.
🧪 3. What Is a Hypothesis?
A hypothesis is a scientific guess about how something works or what will happen.
A good hypothesis should be:
-
Clear and specific
-
Testable with an experiment
-
Based on logic or prior knowledge
✅ 4. Example
🎯 Question:
Why does one plant grow better than another?
💡 Hypothesis:
“If a plant doesn’t get sunlight, it won’t grow.”
🔬 Experiment:
-
Place one plant in sunlight, one in the dark
-
Give both the same amount of water and soil
📊 Results:
The plant in sunlight grows. The one in the dark wilts.
📘 Conclusion:
The hypothesis is confirmed.
🧠 Summary
The scientific method is the foundation of real science.
A hypothesis is a testable idea.
Science works by asking questions, testing ideas, and using results to learn more about how the world works.
