Transcript (mammals, amphibians) Differences How to make a Venn Diagram

Venn Diagrams are tools used to describe and compare
attributes and characteristics of items, to look at how they
are alike and different. It is drawn with at least two
intersecting circles.
Parts of a two circle
Venn Diagram
Similarities between the two items.
Differences between the two
items.
Parts of a three circle Venn Diagram.
Similarities
between the three
items.
Similarities between just
two items (mammals,
amphibians)
Mammals
Have hair or fur
Warm blooded
Babies are born alive
Differences
Breathe air
with lungs.
Amphibians
animals
Have to live part of
life in water
No protective
covering on eggs
Undergo
metamorphosis
into adults
Reptiles
Cold
blooded
Skin covered with
scales.
Vertebrates
Do not have to live
part of their life in
water.
Protective covering
of eggs.
How to make a Venn Diagram
1. Using a compass, draw at least two circles which intersect.
2. Label each circle with the name of each item or category.
mammals
reptiles
3. List all similarities in the intersecting section. List all differences
in the sections which do not intersect.
Reptiles
Mammals
Have hair
or fur
Warmblooded
Babies are
born alive
Breathe
air with
lungs
Skin covered
with scales
Born or hatched
as miniature
replicas of their
parents
Protective
covering on
eggs
Activity Example
1. Gather information on topic. This topic is two different kinds of clouds.
Clouds
Cirrus Clouds
Cumulus Clouds
Form when warm
air rises and
condenses
Vertical
development
Clearly defined
edges
Found low in the
atmosphere
Made of
water
droplets
Color will
tell what
kind of
cloud it is
Thin, wispy
strands
Ice crystals
formed from
the water
vapor
Found very
high in the
atmosphere
If you have more than two items, you must use more circles. The very
middle section will be for similarities for all items. The intersection of the
other circles will be for similarities between just those items. This is an
example of a three circle Venn Diagram for clouds.
Altocumulus Clouds
Formed by
convection
Middle

Cumulus Clouds
Cirrus Clouds
Made of

Ice crystals
formed from
water vapor
High
atmosphere
Formed when
warm air rises
and condenses
Low in
