Clear Question
Clear Question
A specific question that can be tested through an experiment. It should be clear and measurable.
Hypothesis
Hypothesis
A statement explaining what you think will happen in an experiment, based on previous observations or knowledge. It's an educated guess.
Constants
Constants
Factors that are kept the same throughout an experiment to ensure that only the variable being tested affects the results.

Study Notes
Purpose of Experiments
- Experiments test predictions using the scientific method.
- Experiments involve controlled steps to ensure accurate results.
Scientific Method Steps
- Ask a clear question: The question must be specific and testable.
- Example: "Do square ice cubes melt faster than half-moon shaped ice cubes?" is better than "What kind of ice cube melts faster?"
- Formulate a hypothesis: A hypothesis is an educated guess about what will happen based on past observations.
- Example: "Half-moon shaped ice cubes melt faster than square shaped ice cubes."
- Identify constants: Factors that must stay the same throughout the experiment.
- Ensure variables are isolated or accounted for.
- Example: Using the same water source, freezer time, ice thickness, surface type, room temperature, and measurement time for all ice cubes.
- Identify independent and dependent variables:
- Independent variable: The factor you change (e.g., ice shape).
- Dependent variable: The factor affected by the independent variable (e.g., melting rate).
- Measure and record data: Quantify results using appropriate measurement tools.
- Example: Measuring the height of the melting ice cubes and time to complete melting.
- Draw a conclusion: Analyze results to determine if hypothesis is supported.
- Based on data, determine if the prediction held true.
