: What are scientific theories? A: Accepted ideas about how some aspect of the world works, which can be modified over time with new observations.
Q: How do scientists form hypotheses? A: By making initial ideas to explain observations, which can only develop into theories if testable.
What is a hypothesis? Q: A: An initial idea to explain observations, which must be testable
Q: What does it mean if a hypothesis is testable? A: It can be supported or not supported through experiments and observation
Q: What is a controlled experiment? A: An experiment where only one factor (variable) is changed to test its effect.
Q: What is a variable? A: A factor that can change in an experiment, such as temperature or color.
: What is a cause variable? A: The factor that is changed or in an experiment.
Q: What is an effect variable? A: The factor that is measured or observed in response to the cause variable.
Q: Why do scientists carry out multiple runs in experiments? Flashcard 15 A: To reduce errors and verify results.
Q: What is a hypothesis supported by? Flashcard 16 A: Actual observations that match expected results.
: What are the main types of data? Flashcard 17 Q A: Qualitative (descriptive) and quantitative (measurable). Flashcard 33
Q: What is qualitative data? Flashcard 18 A: Descriptions based on observations, e.g., color, smell, shape.
Q: What is quantitative data? Flashcard 19 A: Numerical data, e.g., mass, length, time.
Q: What are some sources of scientific information? Flashcard 20 A: Primary sources (original research), secondary sources (books, journals, internet).

Flashcard 26 Q: What is an anomaly in a trend graph? A: A result that differs significantly from the trend and may indicate an unusual event.
Q: What is a line or curve of best fit? Flashcard 27 A: A line or curve that best describes the pattern of data points.
Q: What is a pattern in data? Flashcard 28 A: A regular or repeated trend observed in data.
Q: What is a pattern graph? Flashcard 29 A: A graph showing how one variable changes in relation to another.
Q: How do scientists interpret graphs? Flashcard 30 A: By describing the pattern, shape, and relationship between variables.
Q: What is the purpose of a conclusion in science? Flashcard 31 A: To summarize what the results tell us about the investigation.
Q: When does an investigation have a valid conclusion? Flashcard 32 A: When it matches the data and the results support the hypothesis.
