fabulous features
3-Ecology concepts: describe 3
interactions between organisms (specific species) that illustrate 3 different
ecological concepts … teacher pays attention to this!
4-Convince your audience that all of
your animals will stay healthy and happy for 30 days
5-Wrap up … receive applause

Mastery Learning ... earning back points on assignments
In order to receive this credit, you are to complete the following on a clean sheet of paper, stapled to the front of the original…
1)
State the new score you anticipate on the assignment.
2)
Rewrite the original question.
3) Reflection: Explain the mistakes you made or the
misunderstanding you had when answering the question initially. The reflections must be thoughtful, complete
and concise.
4)
Re-answer the question or re-work the problem, explaining your correct answer
fully. If the problem is mathematical,
show all steps.
5)
Repeat steps 2-4 for each question on which you wish to earn back points
The packet must be handed in on
or before the third class meeting after the assignment was passed back to the class.
Life Essentials
Basic level of understanding includes …
- Alive
= utilizes energy, changes as it ages, responds to the environment,
reproduce with DNA or RNA, composed of cells
- Virus
= alive? Know the meaning of
virulence
- Species
= distinctive; gene pool; reproductive success = viable and fertile
- KPCOFGS
- Prokaryotic
vs Eukaryotic cells … esp. eukaryotes have membrane-bound organelles
- Binomial
nomenclature … humans are Homo sapiens, Carolus Linnaeus
Proficient level of understanding includes all above, plus…
- Domains:
Archea and Eubacteria, Eukaryae
- Prokaryotic
Domains are Archea and Eubacteria, Eukaryotic Kingdoms are Protista,
Fungi, Plantae, Animalia
- Taxonomy/classification:
grouping of organisms by evolutionary relatedness
- Define
adaptation(as insurance), natural selection(best fit), microevolution
(separates gene pools)
- 5
kingdom system, 6 kingdom system, our understanding changes as new
information comes to light
- Sexual
selection is sexy
Advanced
- Emergent
properties: whole > sum of the
parts; molecules-organelles-cells
- Cladistics
= Phylogeny … the cladogram illustrates relationships over deep time,
lengths of time since split with ancestors, derived characters illustrate
how the similarities between ancestral relatives has changed
- Haeckel
(3 Kingdoms–1860’s), Whittaker(5 Kingdoms–1960’s), Woese(3 Domains–1970’s)
- Define
niche, fitness, selective pressure
- Oldest
Archae & Eubacteria 3400 mya, oldest Eukaryote 1700 mya, oldest
multicellular 600mya
- Examples
- Archae
ex. methanogens, extremophiles
- Eubacteria
ex. E.coli, Spirogyra, Cyanobacteria
- Protista
ex. Euglena, Chlamydomonas, Paramecium,
Amoeba, Algae
- Fungi
ex. Acidophilus, S. cerevisiae,
Mushroom, Slime mold
- Plantae
ex. Arabidopsis (mustard), Teosinte(maize),
Idaho fescue(grass), American Chestnut
- Animalia
Invertebrate ex. C.elegans(worm), Aplysia
(snail), D.melanogaster(fruit fly), Cnidaria (jellyfish and corals)
- Animalia
Vertebrate ex. Zebrafish,
Medaka(ricefish), Fugu, Xenops(African clawed frog), Lab rat/mouse,
guinea pig, Rhesus monkey
Practice of Science Essentials
Basic level of understanding includes …
- Definition
and construction of a testable hypothesis
- Theory
as explanation
- Design
of a controlled experiment
- Distinguish
dependent from independent variable in a controlled experiment
- Qualities
of reliable data
Proficient level of understanding includes all above, plus…
- The
perspective/gestalt of science research
- The
vital role of objective observation in collecting reliable data
- Graphing:
Independent and dependent variables on correct axes, labels & units,
setting appropriate axis-scales
- The
utility of well-designed models
- The 4
qualities of reliable research: replicable, falsifiable, precise,
straightforward
- Distinction
between precision and accuracy
Advanced
- The
most reliable theories are solidly supported by experimental results from
3+ branches of a science
- Reliable
science uses logic to analyze results and meticulously links cause and
effect to describe observable relationships
- It’s
not a scientific theory if it can’t be modified or disproved by new
results. Anecdotes are valuable as
observations, but cannot by themselves prove or disprove a theory
- Occam’s
razor: All else being held equal,
the simplest explanation is usually correct
- Bias: the natural human tendency to wish for
desired outcomes, overcome by conducting experiments rigorously and
analyzing results honestly
