Scientific Method Lab
🔬 Part 1: Scientific Method Knowledge
1. List the six steps of the scientific method in order:
2. Which step comes FIRST in the scientific method?
Form a hypothesis
Ask a question
Conduct an experiment
Analyze data
3. A good hypothesis should use which structure?
Because... then...
If... then...
When... always...
Maybe... possibly...
🧪 Part 2: Baking Soda and Vinegar Experiment
4. Write your research question for this experiment:
5. Write your hypothesis using the "If... then..." format:
6. What is the independent variable (what you will change) in this experiment?
7. What is the dependent variable (what you will measure) in this experiment?
8. List three things you will keep constant (controlled variables):
📊 Part 3: Data Collection
9. Record your experimental data in the table below:
10. What safety equipment should you use during this experiment? (Check all that apply)
