Theme: Organization
•“The whole is greater than the sum of its parts”
I love my bikes
Trek 2300 Road Bike
Novara Ponderosa(“custom build”)
Bike Comparison
•How are they used?
•What is similar about them?
•What is different about them?
Tire Comparison
•How are they used?
•What is similar about them?
•What is different about them?
Parts vs. Whole
•How will I perform on a bike ride with just a tire?
•...just a wheel?
•...just handlebars?
•What do I need for a bike ride?
•All of the parts, properly working together...
Levels of Organization
•One of the things that characterizes life it its many levels of organization.
•Work alone for 3:00 using note/scratch paper
•Goal: make a list, from small (atoms) to large (the biosphere) of the levels of organization that involve living things.
•Start with atoms, then ask yourself, “What do atoms combine to form?”
•I have 11 levels...

CellsCells
•Atom: The smallest piece of unique matter.
•Ex: Carbon, Hydrogen, Oxygen, Nitrogen
•Molecule: Various combinations of bonded atoms.
•Ex: Carbon dioxide (CO2), water (H20), carbohydrate (C6H12O6)
• Polymers: chains of repeating molecule units linked together
•Ex: Glycogen, proteins, DNA/RNA
Levels of Organization
•Organelles: specialized structures inside cells with specific jobs.
•Ex: Nucleus, mitochondria, lysosome
•Cells: basic building block of living things.
•Ex: Nerve cells, muscle cells, skin cells.
•Organs: Combinations of tissues to form structures with specialized function for the body.
•Ex: Brain, heart, kidney, pancreas, leaves
Levels of Organization
•Organism: A single, living individual.
•Ex: Human (homo sapiens)
•Populations: the number of organisms from one species in an area.
•Ex: the number of marmots on Mt. Rainier.
Levels of Organization
•Community: all of the different species interacting in an area.
•Ex: all of the trees, insects, birds, mammals, etc. on Mt. Rainier.
•Ecosystem: all of the living and non-living things that interact in an area.
•Ex: the Mt. Rainier community plus the air, water, soil, etc.
Levels of Organization
•Biosphere:
•Ex: all of the ecosystems (or places where living things are found ) on the planet.
