|
A way of thinking and a way of gathering knowledge about the world that is accurate and reliable |
Science |
|
|
It is like the road map that you follow to get to that destination |
Scientific method |
|
|
Six steps of a scientific method |
Make observations Come up with a question Develop a hypothesis Conduct an experiment Record and analyze results Draw conclusions |
|
|
Format used in making a hypothesis |
If-then |
|
|
These are measurable characteristics or parameters that can be controlled or changed in an experiment |
Variables |
|
|
Three types of variables |
Independent variable dependent variable controlled variable |
|
|
The variable that is being manipulated or controlled |
Independent variable |
|
|
The variable that responds to the changes you have made with the independent variable |
Dependent variable |
|
|
These is the variable that are kept constant or the same during the experiment because they might affect the outcome of the experiment |
Controlled variable |
|
|
This is making sure that in an experiment one factor or condition affects one another by keeping all other conditions constant or the same |
Fair test |
|
|
These are made up of atoms of the same kind |
Elements |
|
|
This is a combination of two or more elements |
Compound |
|
|
The temperature of a substance is |
Fixed and sharp |
|
|
Components and water are separated during the process called |
electrolysis |
|
|
This separates using a spoon or any other scooping material or by picking |
Physical manipulation |
|
|
This can be done to separate the metallic materials from non metallic |
Use of magnets |
|
|
This is the separation of an insoluble solid from a liquid using filter paper |
Filtration |
|
|
In this large particles of insoluble solid are separated from the liquid mixture |
Decantation |
|
|
This separates the soluble solid from the liquid component of the solution by operating the liquid substance |
Evaporation |
|
|
These are the substances that make up a homogeneous solution |
Components |
|
|
What are the components of a solution |
solute solvent |
|
|
This is the component of the solution that is being dissolved |
Solute |
|
|
Is the component of the solution which dissolves the other component |
Solvent |
|
|
This is the measure of the maximum amount of solute that will dissolve in a given amount of solvent at a certain temperature |
Solubility |
|
|
This solution is a solution that contains less solute than the maximum amount it can dissolve at a given temperature |
Unsaturated solution |
|
|
A solution that contains the maximum amount of solute dissolved by a given amount of solvent |
saturated solution |
|
|
A solution in which the maximum amount of solute is greater than the solute solubility at a given volume and temperature |
Supersaturated solution |
