Variables, Data & Constants
These are things in a science experiment that do NOT change.
Constants
An educated guess, a prediction, or an idea you can test.
Hypothesis
Name at least three types of protective gear used in the lab.
Examples:
Apron, goggles, gloves, hair ties, close-toed shoes
In a controlled experiment, this is the ONE thing that you change.
Independent Variable
These are the three words you would use to write a clear hypothesis.
If, then, because
What is the first thing you should do if there is an emergency in the science lab?
Tell an adult
This is something that changes as a result of changes made to the independent variable.
Dependent Variable
This is a well-tested explanation for a series of observations based on fact and evidence.
Scientific Theory
What is the proper method for sampling the odor of a substance in the science lab?
The waft method
This is another word for information that is gathered, organized, and analyzed during a science experiment.
Data
This is a rule that describes a fundamental observation in nature. It can often be expressed as a mathematical equation.
Scientific Law
What might happen if you decided to begin mixing chemicals without instructions in the science lab?
It could release toxic fumes, or it could EXPLODE!
This kind of data can be measured and expressed as an amount or a number.
Quantitative Data
True or False: It is possible for a scientific theory to be elevated to a scientific law if enough evidence can be provided to prove it.
False
You walk into the science lab and notice a bunch of materials laid out on your lab station. What is the rule for these items at the beginning of a lab?
Do not touch unless you have been given instructions to do so (no touchy)
