14 cards
Card 1
Question: What is the purpose of doing an investigation in science?
Answer: To gather evidence that supports or disproves a hypothesis by testing predictions derived from that hypothesis.
Card 2
Question: What are the three key properties evidence should have to be considered reliable?
Answer: Repeatable, reproducible, and valid.
Card 3
Question: What does repeatable mean in an experiment?
Answer: If the same person repeats the experiment using the same methods and equipment, they get similar results.
Card 4
Question: What does reproducible mean in an experiment?
Answer: If someone else repeats the experiment or uses different methods or equipment, they still get similar results.
Card 5
Question: What makes results valid?
Answer: Results are valid when they are repeatable and reproducible and they answer the original question.
Card 6
Question: What is a hypothesis in the context of an investigation?
Answer: A proposed explanation for an observation that can be tested by making predictions and gathering evidence.
Card 7
Question: How do you use a hypothesis to design an investigation?
Answer: Use the hypothesis to make a testable prediction (something you think will happen) and then perform an investigation to gather evidence for or against
Card 8
Question: What is an independent variable?
Answer: The variable you change in an experiment.
Card 9
Question: What is a dependent variable?
Answer: The variable you measure to see the effect of changing the independent variable.
Card 10
Question: What are control variables?
Answer: Variables you keep the same so they do not affect the results.
