1. Elements of Earth’s Crust, Living organisms, Oceans and Atmosphere
6th grade
Teachers: As you review these slides with your students, review the symbols of the elements that are included.

2. Trace the following elements of the periodic table in black that are found in the solid portion of the earth
Element name
Oxygen (O)
Silicon (Si)
Aluminum (Al)
Iron (Fe)
Calcium (Ca)
Sodium (Na)
Potassium (K)
Magnesium (Mg)

3. Draw brown horizontal lines of the elements of the periodic table that are found in living matter
Element name
Hydrogen (H)
Oxygen (O)
Carbon (C)
Nitrogen (N)

4. Shade the elements of the periodic table that are found in the atmosphere with a blue color
Chloride (Cl)
Sodium (Na)
Magnesium (Mg)
Sulfur (S)
Calcium (Ca)
Other elements combined

5. Draw purple dots in the elements of the periodic table that are found in the ocean
Nitrogen (N)
Oxygen (O)
Argon (Ar)
Carbon dioxide (CO2)

6. With your shoulder partner:
Compare the number of shaded elements with the number of elements not shaded.
What did you observe?

7. Solid Earth
The Earth’s crust, also referred to as the lithosphere, is composed of different elements
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 eight elements
Title your pie graph SOLID EARTH

8. The elements in the SOLID EARTH
Element name
Percentage by weight of the Earth’s crust
Oxygen (O)
47%
Silicon (Si)
28%
Aluminum (Al) 8%
Iron (Fe) 5%
Calcium (Ca)
3.5%
Sodium (Na) 3%
Potassium (K)
2.5%
Magnesium (Mg) 2%
Facilitate students construction of pie graph to ensure their accuracy in estimaiong the size of the “pie” for the graph

9. 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

10. The elements in Living Matter
Element name
Percentage found in any cell
Hydrogen (H)
59%
Oxygen (O)
24%
Carbon (C)
11%
Nitrogen (N) 4%
Others elements combined 2%

11. Oceans Majority of Earth’s crust is made up of eight elements
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

12. The elements in the ocean
Percentage

Magnesium (Mg)
7.7%
Sulfur (S)
3.7%
Calcium (Ca)
1.2%
Other elements combined
1.4%

13. Atmosphere Majority of Earth’s atmosphere is made up of four elements
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

14. Elements in the atmosphere
Adapted from :
Elements
Percentage of elements i
Nitrogen (N)
78.09%
Oxygen (O)
20.9%
Argon (Ar)
0.93%
Carbon dioxide (CO2)
0.039%

15. Use the pie graphs you have created to answer the following questions
Which is the most abundant element in the Earth’s crust?
Which is the most abundant element in living matter?
Which is the most abundant element in the oceans?
Which is the most abundant element in the atmosphere?
Which is the most common element found in majority of your pie graphs?
