Study Notes
Scientific Method Steps
- Steps of the scientific method: question, research, hypothesis, experiment, analysis, conclusion.
- Organizing these steps is essential for systematic inquiry.
Lesson Objectives
- Identify scientific method steps effectively.
- Construct proper scientific questions.
- Conduct experiments and analyze results.
- Reference information using Harvard style.
Scientific Question
- Defines a problem and the goal of an experiment.
- Must be objective, testable, and based on facts.
- Should focus on one variable at a time.
- Examples include:
- Impact of artificial sweeteners on students.
- Growth of plants in different soil types.
Constructing Scientific Questions
- Well-constructed: clear, focused, and empirical.
- Poorly constructed: vague or subjective, such as "Why do plants grow?".
- Effective examples include investigations of liquid effects on plant growth and temperature/humidity impacts on evaporation rates.
Conducting Research
- Should summarize scientific concepts in 1-2 paragraphs.
- Paraphrase information in your own words.
- Use credible sources and avoid unreliable references (e.g., Wikipedia).
- Proper citation includes author, publication year, article title, website address, and access date.
Hypothesis
- A clear prediction based on existing knowledge that answers the scientific question.
- Must include relationships between independent and dependent variables.
- Example:
- Question: Does adding batteries affect bulb brightness?
- Hypothesis: More batteries will increase bulb brightness.
- Question: Does adding batteries affect bulb brightness?
Variables
- Independent Variable (IV): what is changed (e.g., amount of batteries).
- Dependent Variable (DV): what is measured (e.g., brightness of the bulb).
- Control Variables: factors kept constant throughout the experiment (e.g., bulb type, environment).
Experiment Design
- Specify all variables in bullet points.
- List materials required for the experiment, ensuring they are safe and accessible.
- Write a clear, replicable procedure with sequential steps.
- Document observations and results accurately during the experiment.
Important Notes on Fair Testing
- Ensure experiments are fair and repeatable.
- Consider the necessary controls to maintain experimental integrity.
- Use visuals when possible to enhance understanding.
