Objective: By the end of this slideshow, students will: Understand what a Venn Diagram is Know how to formulate a simple Venn Diagram Will work with a partner to complete a simple 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 Differences between the two items. Similarities between the two items.

Parts of a three circle Venn Diagram. animals Breathe air with lungs. Reptiles Skin covered with scales. Do not have to live part of their life in water. Protective covering of eggs. Mammals Have hair or fur Warm blooded Babies are born alive Amphibians Have to live part of life in water No protective covering on eggs Undergo metamorphosis into adults Cold blooded Vertebrates Similarities between the three items. Similarities between just two items (mammals, amphibians) Differences

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. mammalsreptiles

3. List all similarities in the intersecting section. List all differences in the sections which do not intersect. Mammals Reptiles Breathe air with lungs Have hair or fur Warm- blooded Babies are born alive 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. Cumulus Clouds Cirrus Clouds 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 Form when warm air rises and condenses Vertical development Clearly defined edges Found low in the atmosphere Clouds

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 Cumulus Clouds Cirrus Clouds Formed by convection Middle atmosphere Ice crystals formed from water vapor High atmosphere Formed when warm air rises and condenses Low in atmosphere Made of water droplets
