SCIENCE SKILLS
It is gathering information using the senses.
Observation
This tool is used to observe tiny organisms and cells.
Microscope
Matter is anything that has this and occupies space.
Mass
The substance being dissolved in a solution.
Solute
The first step of the scientific method where scientists gather information.
Observation
It is an explanation based on observations and prior knowledge.
Inference
This tool measures the volume of liquids accurately.
Graduated Cylinder
In this state of matter, particles are tightly packed and vibrate in fixed positions.
Solid
The substance that dissolves the solute.
Solvent
A possible explanation or educated guess about a problem.
Hypothesis
It is an educated guess about what may happen in the future.
Prediction
This laboratory tool produces heat or flame.
Bunsen Burner
Ice melting is an example of this type of change.
Physical Change
A solution that can still dissolve more solute.
Unsaturated Solution
The variable intentionally changed by the investigator.
Independent Variable
It is the standard system of measurement used worldwide.
Si Unit
This error happens when liquid measurement is read from the wrong angle.
Parallax Error
A change that forms a new substance with different properties.
Chemical Change
A solution containing the maximum amount of dissolved solute.
Saturated Solutio
The variable that responds to changes in the independent variable.
Dependent Variable
It is a representation of objects or ideas that helps scientists explain difficult concepts.
Scientific Model
This safety symbol warns that a substance may be poisonous or harmful.
Toxic Symbol
In gases, particles are far apart and move freely because of large spaces between them.
Gas
This type of concentration expresses the mass of solute in a given volume of solution and is commonly used in medicines.
Percent by Mass/Volume
The final step where scientists summarize findings and determine if the hypothesis is supported.
Drawing Conclusions
