1. Warm up 11-2-18 The most basic unit of structure and function is?
Organ
Organism
Cell
Tissue

2. What is a System?
Think about the pen you may be holding. Does it have parts? Do they work together to do a job? Yes! A pen has the case, the tube that holds the ink, the ink, the ballpoint and it may even have an erasure if it contains erasable ink. If it clicks to open and close it will have a spring and a part to make the point go in and out. All of these parts work together so you can write with the pen. That makes it a system!
So, a system is a group of parts that work together to perform a function. What is a function? The parts of a pen work together so you can write with it. That is its function. A function is the job a system performs.

3. Examples of Systems
What are the names of each part in this system and what function do they perform?
What would happen if the keyboard or mouse stopped working?

What would happen if the engine stopped working?

6. Levels of Organization Notes

7. ATOMS
Smallest part of matter
NON-living

8. Molecules
2 or more bonded atoms
Form compounds
NON-living

9. Macromolecule
Very large complex molecules (made of a bunch of smaller molecules that are the same) (monomers.)
All living things are made up of proteins, fats, carbohydrates, and nucleic acids.
NON-living
The macromolecules are mainly made of carbon, hydrogen, and oxygen but in different ratios. This gives each compound different properties.

10. Ex: nucleus, mitochondria
Organelles
“Tiny organs”
Made of macromolecules
Non-living
Ex: nucleus, mitochondria

11. Ex: plant cell, skin cell…
Made of organelles
Basic unit of structure & function
LIVING
Ex: plant cell, skin cell…

12. Ex: muscle tissue, nerve tissue
The SIMILAR cells working together
Living
Ex: muscle tissue, nerve tissue

13. Organs
SIMILAR tissues that work together
Living
Ex: heart, stomach…

14. Ex: skeletal system, nervous system
Organ Systems
Organs that work together for similar purpose
Living
Ex: skeletal system, nervous system

15. Organism Ex: human, dog Entire living things (organisms)
Usually made of systems
May be a single cell
Living
Ex: human, dog

16. Video Clip- Levels of Organization

17. Think, Pair, Share:
Can you put the following items in order from smallest to largest? Organ, Cell, Organ System, Tissue, Organism
**Think to yourself first! Then quietly discuss with table partner…be ready for me to call on you to share!

18. Population
Same organisms living together
Ex: group of penguins

19. Ex: penguins, polar bears
Community
Several populations living together
Populations interact
Ex: penguins, polar bears

20. Ecosystem
A biotic (living) community and the abiotic (nonliving) features
Ex: penguins, polar bears, temperature, & sun

21. Biome
Similar ecosystems on earth together
Ex: arctic tundra

22. Biosphere Whole living layer on Earth Includes abiotic features

23. Tissue Organ System Organism Atom Molecule Macromolecule Organelle
Cell

24. Summary Statement on the bottom of organizer:
Look back at the title of these notes and think about how it was organized…
Write 1-2 sentences summarizing what you just learned on this page.

25. Reading Activity- The Organization of the Human Body
Read & follow directions on sheet provided

26. Warm up
Write 2 examples of an ORGAN and 2 examples of ORGAN SYSTEMS…
Possible Answers: Organs- heart, lungs, brain, skin, stomach, intestines, bones
Organ Systems- circulatory, respiratory, nervous, integumentary, digestive…

27. Building Blocks of the Body
Bone cell
Muscle cell
Epithelial cell
White Blood Cell (WBC)
Red Blood Cell (RBC)
Masses of Muscles
Skeletal muscle– attaches to bones
Smooth muscle – found in digestive tract and walls of blood vessels.
Cardiac muscle– found in the heart

28. How many bones does the human body have?
Mind Stretcher:
How many bones does the human body have? 12
4,560
C. 630
D. 206

29. Ticket out the Door- “Shout” Out
Think of your own example of something abiotic (non-living) that works together as a system.
What are the parts included in this system and what are their functions?
