Which is the most common
 element in the Earth’s crust?
Which is the rarest single
 element in the Earth’s crust?
The most common elements in
 the Earth’s crust are rarely

 elements chemically
 combined together?
Which element might be the
 most expensive? Give a
 reason why you think so.
  Color the elements percentage in
  your 100% circles that are found
  in living matter

Living Matter
› Anything that consumes energy, wastes
  energy, responds to stimuli, grows and
  reproduces
› Majority of living matter is composed of four
  elements
› Use the following data to construct a pie
  graph showing the percentage of each of
  the four elements
› Title your pie graph LIVING MATTER
     Color the elements and compound
    percentage in your 100% circles that
       are found in the atmosphere.
Elements                Percentage
Nitrogen (N)            78
Oxygen (O)              21
Argon (Ar)              0.9
Carbon dioxide (CO2) 0.0314
Neon (Ne)              0.002
Atmosphere
› Layer of gases that surround the earth
› Majority of Earth’s atmosphere is made up of
  four elements
› Use the following data to construct a pie
  graph showing the percentage of each of
  the four elements
› Title your pie graph ATMOSPHERE
    Color the elements and compounds
  percentage in your 100% circles that are
             found in the ocean


         Elements            percentage
     Chlorine (NaCl)             55

Other elements combined          0.7
Oceans
› More than half of the earth is covered in salt
  water
› Majority of Earth’s crust is made up of eight
  elements
› Use the following data to construct a pie
  graph showing the percentage of each of
  the five elements
› Title your pie graph OCEANS
  Use the pie graphs you have created
    to answer the following questions
1. Which is the most abundant element in
   the Earth’s crust?
2. Which is the most abundant element in
   living matter?
3. Which is the most abundant element in
   the oceans?
4. Which is the most abundant element in
   the atmosphere?
5. Which is the most common element
   found in majority of your pie graphs?
