Testable Question
●What is a testable question?
A question that is able to be tested and measured.
What is a variable in an experiment?
A factor that can change in the experiment.
What is an experiment?
A test done to find out how something works.
What does data collection mean in science?
Gathering information during an experiment.
What is an explanation in science?
An answer that explains what happened in an experiment.
●Give an example of a testable question about plant growth.
How does that amount of sunlight affect how tall a plant grows?
How does that amount of water given to a plant affect its growth?
Does the type of soil affect how fast a plant grows?
Name the two main types of variables.
(Test variable) Independent variable
and (Outcome variable) dependent variable.
Why do scientists conduct experiments?
To learn new things and find answers to questions.
Name two ways scientists can collect data.
By measuring or observing.
Why do scientists need to explain their findings?
So others can understand what they learned.
●Why do scientists need testable questions?
What is a TEST variable or independent variable?
The part of the experiment that you change
List the steps of a scientific experiment.
Ask a question, make a hypothesis, test it, collect data, and draw conclusions.
Why is it important to collect data in an experiment?
So you can learn from the experiment and make conclusions.
What does an explanation try to answer?
It tries to explain why something happened.
What is the difference between a testable question and a non-testable question?
A testable question can be answered by doing an experiment; a non-testable question cannot.
How does a dependent variable change in an experiment?
It changes because of the independent variable.
What is a hypothesis in an experiment?
A guess about what will happen based on what you know. (prediction)
What is the difference between qualitative and quantitative data?
Qualitative data is about qualities (like color), and quantitative data is about numbers (like height).
How do scientists communicate their explanations to others?
By writing reports or sharing their results with other scientists.
How can a testable question lead to a better understanding of a scientific concept?
It helps scientists find out how things work by testing them.
Why is it important to control variables in an experiment?
To make sure nothing else affects the results.
How do scientists ensure their experiments are fair?
By keeping everything the same except for what they are testing.
How can data collection help scientists draw conclusions?
It shows whether their ideas were correct or not.
Why is it important to back up explanations with evidence?
So people know the explanation is true and not just a guess.
