unit? YES or NO What is a cubic meter a measurement for? Volume 1 cm high x 1 cm long x 1 cm wide = 1 cm Is cubic centimeter a metric

unit? YES!!! Convert 25.6 cm = __?__ Dm 0.0256 Dm Dm 25.6 cm = _______

How did we get that? KHDBDCM 0.025.6 What are the steps of the scientific method?

What is important about a hypothesis? Problem/Question Hypothesis Experiment

Scientists want to know why things happen Scientists develop an If, then statement. Scientists must be able to TEST their hypothesis

Scientists test their hypothesis Data Analysis Scientists look at their data

Conclusion Was their hypothesis supported or refuted? Why or why not?

Report Findings Scientists want others to know and they can also test the findings Normal Sun

Measuring plant height (growth) after 7 days. What is the INDEPENDENT VARIABLE? I.V. = Amount (Hrs) of Sun given to the

plants What I change in the experiment. Normal Sun 1 Hr of Sun

2 Hrs Sun 3 Hrs of Sun Measuring plant height (growth) after 7 days.

What is the DEPENDENT VARIABLE? D.V. = The height of the plants after 7 days The Data collected.

Which is the Zoologist and which is the Botonist? Name the levels of living things.

Biosphere = All areas of earth with life Ecosystem = Living and non-living in an area Community = Different species in an area Population = Same species (organisms) in an area Organism = Group of organ systems make up this

Organ system = Group of organs working together Organ = Group of tissues working together Tissue = Group of cells working together Cell = SMALLEST LIVING THING Molecule = Units that make up cells NOT LIVING

What is Taxonomy? Who was the Father of Taxonomy? What is Taxonomy? System of classifying and naming

living things Who was the Father of Taxonomy? Linneaus What 2 kingdoms did Linneaus first

recognize? How many taxons were in his taxonomy system? Name them from largest to smallest

What 2 kingdoms did Linneaus first recognize? Plant & Animal How many taxons (levels) were in his taxonomy system? 7

Name them from largest to smallest Kingdom, Phylum, Class, Order, Family, Genus, Species (King Phillip Came Over For Green Soup) What system did Linneaus

create to help name species? What 2 parts are in this naming system? What language is used in names?

What system did Linneaus create to help name species? Binomial Nomenclature What 2 parts are in this naming system? Genus species

(scientific name) What language is used in names? Latin Do these animals belong to the same species or genus? Ursus arctos

Ursus collaris Ursus beringianus These animals belong to the same Genus Ursus arctos

Ursus collaris Ursus beringianus What taxon was added to make 8 taxons in the MODERN system

of classification? DOMAIN was added to make 8 taxons in the MODERN system of

classification How many DOMAINS ? Name them! How many KINGDOMS? Name them! How many DOMAINS ?

3 Bacteria, Archae, Eukarya How many KINGDOMS? 6

Eubacteria Archaebacteria Protista Fungi Plantae Animalia

Why do we classify living things? Give 4 reasons Why do we classify living things? Give 4 reasons

Universal Naming Method (Common names are different in various locations

around the world making it difficult to talk about an animal. Ex: puma, mountain lion, cougar) Organizes living things Easier to study living things Looks at relationships Traditional classification is based

on ____________ characteristics. Evolutionary classification is based on ____________ characteristics. Molecular (clock) classification is based on ____________. Traditional classification is based

on shared physical characteristics. Evolutionary classification is based on derived characteristics. Molecular (clock) classification is based on DNA and Time. EVOLUTIONARY Classification uses

derived characteristics to show evolutionary descent from a single ancestor. It uses what type of tree? EVOLUTIONARY Classification uses derived characteristics to show evolutionary descent from a single

ancestor. It uses a cladogram! What is a dichotomous key? What is a dichotomous key? Lists paired choices (1.a or

1.b etc.) to lead you to the organisms name. Be able to use one!!!!

Eubacteria and Archaebacteria belong to what group of organisms: Prokaryotes or Eukaryotes? What is the difference between Prokaryotes and Eukaryotes?

Eubacteria and Archaebacteria belong to what group of organisms: Prokaryotes Prokaryotes: No Nucleus or membrane bound organelles

Eukaryotes: Have a nucleus and organelles What are autotrophs and what kingdoms do they belong? What are heterotrophs

and what kingdoms do they belong? What are autotrophs? They make their own food (energy) mostly by photosynthesis (Plants,

Some Protista, Some Archae, Some Bacteria) What are heterotrophs? They must consume their food for energy (Animals, Fungi, Some Archae, Some Bacteria,

Some Protista) What Kingdom was first considered to be in the Plant Kingdom? What Kingdom was

first considered to be in the Plant Kingdom? Fungi What are extremophiles? What Kingdom are they from?

Extremophiles = bacteria that can live in extreme conditions (hot, cold, salty) Kingdom = Archaebacteria What is metabolism?

What is metabolism? Process of gaining and using energy Know the key points of the

Classification of Living Things Chart that you were given in class and be able to use one to identify information from it.
