What is an example of a limitation of a model.
They don't act exactly like the things they model
Mass
the amount of matter that something is made of
The difference between volume/mass
Volume is the amount of space taken up by an object, and mass is the amount of matter an object contains.
Technology
the application of knowledge, tools, and materials to solve problems and accomplish tasks
To be valid, a hypothesis must be
testable and supported by evidence
Theory
a unifying explanation for broad range of hypotheses and observations that have been supported by testing
Explain the difference between science/technology.
Science is a process of observing and asking questions about the natural world. Technology is the application of science knowledge and the use tools to solve everyday practical problems.
Scintific methods
the ways in which scientists answer questions and solve problems
How many milliliters are in 3.5kL?
3,500,000 mL
Density
the amount of matter in a given volume
The difference between observation/hypthesis
An observation is any use of the senses to gather information. A hypothesis is a possible answer to a question. Hypothesis can be tested. Observations can be used to develop and test hypotheses.
Hypothesis
A possible explanation or answer to a question

the basic SI(International System of Units) of length
The difference between model/theory.
A therory is an explanation for how something happens. A model can represent an explanation or some aspect of the theory.
model
a representation of an object or system
The difference between area/density
Area is the amount of surface an object has, while density is the amount of matter in a given volume
Mass
the amount of matter
observation
Any use of the senses to gather information
Data
any pieces of information gathered through experimentation
Area
a measure of how much surface an object has
Volume
the amount of space that something occupies or the amount of space something contains
Temperature
a measure of how hot(or cold) something is
