Scientists make this kind of educated guess before starting an experiment.
What is a Hypothesis?
Centimeters, millimeters, and decimeters are all smaller units of meters, the base unit scientists use to measure this.
What is Length?
This type of graph shows parts of a whole as slices
What is a Circle(or Pie) Graph?
This is a personal belief or feeling that is not based on facts and should not be used in science.
What is an Opinion?
This is information you gather using your senses or tools to study the world
What is an Observation?
This is the broad study of the natural world through asking questions and testing ideas.
What is Science?
This is the amount of matter in an object, often measured in grams, milligrams, or kilograms.
What is Mass?
Scientists use this type of graph to show how one variable changes compared to another, often over time
What is a Line Graph?
This happens when a scientist only looks for evidence that supports what they already believe.
What is Confirmation Bias?
This describes what happens in nature and is known to be true all of the time
What is a Law?
In an experiment, this is the factor you measure to see how it changes because of the independent variable.
What is the Dependent Variable?
This is the amount of space an object takes up, measured in Liters.
What is Volume?
This type of graph uses bars to compare different groups or amounts.
What is a Bar Graph?
This happens when the people or items chosen for a study are not representative of the whole group.
What is Selection Bias?
This is a well-tested explanation based on many repeated observations that can be used to explain how/why things in our world work
What is a Theory?
This is the organized and controlled test you do to find out if your hypothesis is right or wrong.
What is an Experiment?
In science, this is an agreed-upon unit or measurement everyone uses so results are the same everywhere.
What is a Standard?
On a graph, this horizontal axis shows the independent variable
What is the X-Axis?
In an experiment, these are the factors you must keep the same to make sure only the independent variable causes change.
What are Constants?
This is the use of science and knowledge to make life easier and solve problems
What is Technology?
In an experiment, this is the one factor you change on purpose to test your hypothesis.
What is the Independent Variable?
This is a unit made by combining two or more base units, like cm^3, g/L, or km/s
What are Derived Units?
On a graph, this vertical axis shows the dependent variable
What is the Y-Axis?
This is a factor in an experiment that you did not plan for but that can change the results and confuse the conclusions.
What is a Confounding Variable?
A representation of a real-world system, phenomenon, or process that helps scientists understand and explain things that are too complex, large, small, or abstract to study
What is a Model?
