THE HEART Scientific Model - Coggle Diagram
THE HEART
Scientific Model
Benefits of my model
#
shows different blood
blue = deoxygenated
red = oxygenated
easier to understand / simplified
the parts of the heart
different veins and arteries
the different vavles
shows the inside of the heart
inside of arteries and veins
help understand scientific concepts
3D
see into the heart
cheap to construct
separation of the sides of the heart
ethical
no mess
Limitations of my model
#
not colour correct
veins are not blue
inside of veins/arteries are not black
does not show layers of the heart
not not include all aspects
electical wiring
not exact size
simplified
does not show functioning heart
beating
blood flow / direction
does not show other heart aspects
where the blood travels
the outside of the heart
the circulatory system
does not demonstate process
Main features of a heart model
valves
veins
Arteries
Aorta
brachiocephalic trunk
left common cartoid artery
left subclavian artery
Layers of the heart
outside muscles of heart
electrical wiring of the heart
Effectiveness
defined purpose
show inside of heart
shows oxygenated and deoxygenated blood

Scientific Models
Benefits
make predictions
e.g. climate change models
atmospheric models
enable us to make predictions
easier to understand
simplify difficult concepts
demonstrate variable relationships
Limitations
missing detail
can't incorporate all details
too complex
Approximations
predictions based on observations
simplicity
loose details
always be imperfections
limitations
description of a natural phenomenon
make predictions
make inferences
types of scientific models
diagrams
physical replicas
#
mathematical representation
computer simulations
analogy
Background Information
the heart
circulatory system
essential for body function
