1. Lesson Objective:
You will be able to identify the elements that make up the majority of Earth’s lithosphere, biosphere, hydrosphere, and atmosphere.

2. Think-Pair-Share
What 10 elements do you think make up the majority of the human body?

3. If this embedded video does not work, the link is https://www. youtube

4. What does “abundant” mean?

5. Abundant = a large amount of something

7. The Earth’s Crust: The Crust is part of the Earth’s Lithosphere.
Outermost layer.
Where we live!
47% Oxygen.
28% Silicon.

8. What are the chemical symbols for the 2 elements that make up the majority of the Earth’s crust?

9. 8 16 14 28
& O Si
Oxygen
Silicon

10. The Hydrosphere:
The hydrosphere is made up of all of the bodies of water on the Earth.
Oceans, rivers, lakes, streams, etc.

11. Why Do Oceans Matter?

12. What is the chemical formula for water?

13. Which of the two elements has a larger atomic number, Hydrogen or Oxygen?

14. Oceans:
The Earth’s oceans are:
1. 86% Oxygen
2. 11% Hydrogen

15. What is the “atmosphere”?

16. Earth’s Atmosphere
The Earth is wrapped in a blanket of air called the atmosphere, which is made up of several layers of gases.

17. Earth’s Atmosphere The Earth’s Atmosphere is: 1. 78% Nitrogen.
2. 21% Oxygen.
3. 1% other gases.

18. What do you think the word “Biosphere” means?

19. Bio = Life

20. The Biosphere
The Biosphere contains all living matter on Earth.

21. The Biosphere: 4 elements make up 96% of living matter. 1. Oxygen
2. Carbon
3. Hydrogen
4. Nitrogen

22. Which of the following is primarily made of Nitrogen
Which of the following is primarily made of Nitrogen? A – Biosphere B – Hydrosphere C – Atmosphere D - Lithosphere

23. Which sphere contains all of Earth’s body of water
Which sphere contains all of Earth’s body of water? A – Atmosphere B – Biosphere C – Hydrosphere D – Lithosphere

24. Which element is not a major part of the biosphere
Which element is not a major part of the biosphere? A – Hydrogen B – Oxygen C – Helium D – Nitrogen

25. The lithosphere is mostly – A – Silicon and Carbon B – Silicon and Oxygen C – Oxygen and Carbon D – Oxygen and Nitrogen

26. The 4 Spheres Diagram Level 1 voice.
In your notebook, divide a page into 4 quadrants.
Label each quadrant one of the spheres.
Write a sentence describing it and the elements that make it up.
Draw a picture that represents it.
I have students fold a piece of construction paper into four quadrants and then have them illustrate and define each sphere.
