Study Notes
What is a Scientific Hypothesis
- A scientific hypothesis is an educated guess that is testable, clear, and based on observations and prior knowledge, written before an experiment takes place.
Creating and Developing a Hypothesis
- Step 1: Ask a specific and researchable question, using who, what, when, where, why, or how.
- Step 2: Conduct preliminary research, gathering reliable sources, case studies, and personal observations to inform the hypothesis.
- Step 3: Answer the initial question based on preliminary research.
- Step 4: Write a hypothesis, including variables and predicted results, using an if/then statement.
Characteristics of a Good Hypothesis
- A good hypothesis is testable, clear, and includes variables and predicted results.
- Examples of well-written hypotheses:
- "If a person gets 8 hours of sleep at night, then their memory during the day will improve."
- "If teeth are brushed twice a day, then a person is less likely to develop cavities."
Characteristics of a Poor Hypothesis
- A poor hypothesis is not testable, lacks variables, is an opinion, or is not based on facts.
- Examples of poorly-written hypotheses:
- "It doesn't matter if you do your homework or not."
- "Lightning is caused by ghosts in the sky."
- "Fertilizer is better for flowers than it is for vegetable plants."
- "Ice cream tastes the best at midnight"
