Term
Model
Definition
a representation that explains how something is built or how it works
Term
Conceptual model
Definition
explanations that are expressed in drawings or words or mathematics
Term
Physical model
Definition
a three-dimensional construction designed to explain how something works
Term
Heliocentric model
Definition
a model of the solar system which places the Sun in the center and the planets revolving around the Sun
Term
telescope
Definition
an instrument used to study objects far away, such as planets, and stars.
Term
microscope
Definition
instrument used to study objects that are very small, such as cells
Term
prototype
Definition
an original model based on something to be built
Term
limitations
Definition
part of a design that restricts the completion of that product
Term
prosthesis
Definition
a device that is a replacement for a body part
Term
inference
Definition
drawing a conclusion or making a reasonable judgement
Term
When do you use a model?
Definition
when something is to small or to large to work with.
Term

Definition
Galileo
Term
Who created the cell theory?
Definition
Robert Hooke
Term
What is the cell theory?
Definition
That all living things are made out of cells.
Term
How did Hooke discover this cell theory?
Definition
With a microscope
Term
Why would one want to make a prototype?
Definition
to work through possible problems a real invention might have. Also to determine limitations in that object and think about cost.
Term
What are some examples of limitations?
Definition
cost(to expensive) , design (doesn't work)and resources(not enough supplies to build)
Term
Who used a Glider as a prototype?
Definition
The Wright Brothers
Term
Who might need a prosthesis?
Definition
someone born without a body part or lost a body part in an accident
Term
Do scientists use prototypes to build a prosthesis?
Definition
yes
Term
Robotics
Definition
is a machine or device that can be programmed to perform certain jobs.
Term
Where are robots used today?
Definition
in factories on assembly lines
Term
Bionics
Definition
the combination of using robot like parts on a human body to replace a body part
Term
collaboration
Definition
is when scientists work together to discuss and learn from each other; share data.
Term
inference
Definition
to draw conclusions or make a logical judgement. Scientists do this when they collaborate on a project.
