Laws and Theories
100
It's what you do if an accident happens in the lab.
What is tell the teacher?
100
It's the type of scientific investigation that involves making a representation of something.
What is modeling?
100
It's a scientific statement that can be tested.
What is a hypothesis?
100
This is a variable that "I" can change to see how it affects another variable.
What is an independent variable?
100
It's something that is discovered to always be true, even if we don't yet know why.
What is a scientific law?
200
It's a type of safety equipment to protect the eyes.
What are goggles?
200
In this type of investigation you use your senses or instruments instead of doing an experiment.
What is observation?
200
It's when you do your experiment several times and take an average for more accurate results.
What is repetition?
200
This is a kind of data that you can observe but you can't measure with a number.
What is qualitative data?
200
This is a well-supported explanation based on a lot of evidence and testing.
What is a theory?
300
This is what should be done with long hair for safety in a laboratory.
What is tie it back?
300
You use this type of investigation to test a hypothesis using the scientific method.
What is experimentation?
300
It's when someone else does an experiment similar to yours to see if they get the same result.
What is replication?
300
This type of graph is a visual representation of data using rectangular bars, where the height of each bar is proportional to the value it represents.
What is a bar chart (or bar graph)?
300
True or false - A theory is a person's opinion or guess.
What is false?
400
It's something you're not allowed to do in a laboratory.
What is eating, drinking, or horseplay?
400
It the type of data that is a measurement expressed as a number.
What is quantitative?
400
It's a summary of what you discovered after you perform an experiment and analyze the results.
What is your conclusion?
400
This is the variable you measure to see how it depends on the variable that you changed.
What is a dependent variable?
400
True or false - A theory can become a law or a fact if there is enough evidence.
What is false.
A theory is the best explanation we have for something, and is built on laws and facts.
500
It's what you should do instead of sniffing a chemical to identify it.
What is wafting?
500
It's a reasonable conclusion you can make based on an observation.
What is an inference?
500
It's what biology, geology, physics, astronomy, etc. are all examples of.
What are fields (or disciplines) of science?
500
This kind of graph shows data as a series of points connected by lines, showing changes and trends in a variable over time .
What is a line graph?
500
True or false - A theory can change or be refined over time as new discoveries become available.
What is true?
New discoveries add to the knowledge that theories are built on.
