Models can be helpful in scientific investigations because
It may not be possible to work safely with the real thing.
They can be smaller and easier to study than the real thing.
They can be larger and easier to examine than the real thing.
all of these answers are correct.
A yellow coconut could be used to represent the sun because it's round and yellow.
Which of the following could also be used to model the sun because they share similar characteristics?
a light bulb
an empty cup
an eraser
Which of the statements are INCORRECT about models.
Models must be exactly like what is being modeled.
Models communicate information.
Models can be modified and improved.
Models can be drawings with labels.
Models are used to better explain and understand a complex thing.
True
False
Two models of the same phenomenon can be very different because they may be explaining two different ideas about the same object or system.
True
False
More than one model of the phenomenon can be equally valid and useful, as long they both can explain the phenomenon and be used to make predictions about how the system works.
True
False
All models have _______________. Even good models can often be made better.
replicas
computer simulations
limitations
drawings
Once a scientific model is made, scientists ...
never change it. Scientists never change their minds, and always stick with their first ideas about a phenomenon.
can always modify and improve it. Models should be updated to reflect the most current understanding of the phenomenon.
don't do any more research on that topic. Models are only made once scientists understand everything about a phenomenon.
become super famous. It is very difficult to make a model. Only the most advanced scientists are allowed to create models of phenomena.
Which of these is not a model?
Which of the following is a key reason why scientists create models?
To prove their hypotheses without testing.
To simplify complex systems for better understanding.
To eliminate the need for experiments.
In scientific modeling, a model is considered effective if it can...
accurately predict outcomes and explain phenomena.
be created without any data or research.
only represent the physical characteristics of an object.
Which of the following statements about models is TRUE?
All models are perfect representations of reality.
Once created, models cannot be changed.
Models can help visualize and understand complex ideas.
Which of the following is an example of a model used in scientific research?
a random guess
a personal opinion
a weather forecast
