process of science

Definitions  

- Science: The process of learning about the world by observing, experimenting, and thinking logically.  

- The scientific method: A step-by-step process used to answer questions and test ideas.  

- Hypothesis: An educated guess about what will happen in an experiment.  

- Falsification: The idea that a hypothesis or theory can be shown to be wrong through evidence.  

- Theory: A well-supported explanation of something based on a lot of evidence and experiments.  

- Law: A statement that describes a natural phenomenon that always happens under certain conditions, often expressed mathematically.  

- Independent variable: The factor you change or manipulate in an experiment. 

- Dependent variable: The factor you measure or observe, which depends on the independent variable.  

- Standardized variable: Things that stay the same in all parts of the experiment to keep it fair.  

- Experimental group: The group that gets the treatment or change you're testing in the experiment.  

- Control group: The group that doesn’t get the treatment, used to compare with the experimental group.  

- Positive control: A group or condition expected to give a positive result, making sure the experiment works.  

- Negative control: A group or condition that should show no effect, used to see what happens without any treatment.  

- Analysis: The process of looking at the experiment data to understand what happened.  

- Conclusion: A decision made after reviewing the data to see if the hypothesis was correct or not.

Questions and Answers  

1. Outline the main steps of the scientific method.  

   - Ask a question: Figure out what you want to learn about.  

   - Do background research: Find out what’s already known about the topic.  

   - Form a hypothesis: Make a guess about what you think will happen.  

   - Design an experiment: Plan how you’ll test your hypothesis.  

   - Conduct the experiment: Do the experiment and collect the results.  

   - Analyze the data: Look at the results and see if they support your hypothesis.  

   - Draw a conclusion: Decide if your hypothesis was right or wrong.  

   - Share results: Tell others about what you found out.  

2. What does it mean to falsify a hypothesis?  

   To falsify a hypothesis means to show that the hypothesis is wrong by providing evidence or conducting an experiment that disproves it. In science, we can’t fully "prove" a hypothesis is true, but we can prove it’s wrong.
