
(who, what, where, why)
Measurable: How will you demonstrate and evaluate
the extent to which the goal has been met?)
Achievable: stretch and challenging goals within
ability to achieve outcome. What is the actionoriented verb?
Relevant: How does the goal tie into your key
responsibilities? How is it aligned to the objectives?
Timely: Set one or more target dates (including
deadlines, dates and frequency), the “by when” to
guide your goal to successful and timely completion
1. I will lose weigh
2. I will lose weigh by June 1st by walking 20 minutes a
day.

List 3 safety rules you have
learned in your previous
science classes.
Science
 Uses evidence to construct
testable explanations and
predictions of natural
phenomena
 Generates knowledge
 Science assumes that everything in the universe can be
explained, given enough data and experimentation.
 All ideas in science are constantly being tested,
evaluated, and re-considered.
 Hypothesis: Testable prediction based on prior
knowledge and observation.
 Can be supported or rejected based on an experiment.
 Theory: Broad explanation based on many experiments
and high amounts of data.
 Examples: Evolution, Plate Tectonics, Big Bang
 Discoveries must be reproducible -- designed and
recorded such that the results can be repeated by other
researchers.
19
 Many of the original understandings of life came from
philosophers who did not actually conduct experiments,
rather using logic and reason.
 A far different idea is pseudoscience, which appears or
claims to be science, but does not follow scientific
principles.
21
 Aristotle, an influential Greek philosopher, proposed
that life could arise from non-living matter.
“So with animals, some spring from parent
animals according to their kind, whilst others
grow spontaneously and not from kindred
stock; and of these instances of spontaneous
generation some come from putrefying earth
or vegetable matter, as is the case with a
number of insects, while others are
spontaneously generated in the inside of
animals out of the secretions of their several
organs.“
—Aristotle,
History of Animals, Book V, Part 1
 The theory that life arose spontaneously from non-
living matter persisted from ancient times through the
19th century.
 One recipe for life called for dirty garments and husks
of wheat to be added to a jar.
 Wait 21 days, and mice appear!
 This belief was based in false
science.
 Could it be replicated
consistently?
 Were any other possible
explanations tested?
23
 Scientific investigations begin with observation, the
act of noticing and describing events or processes in a
careful, orderly way.
 A hypothesis is an explanation for an observation
based on prior knowledge.
 Aristotle’s idea of spontaneous generation began with
the observation that maggots would arise from meat or
dead flesh, fleas from dust, tapeworms from other
organisms, etc.
 During Aristotle’s time, all scientific ideas were based
on thought and logic, not experimentation.
 Experiments test a hypothesis under controlled
conditions.
 Whenever possible, a hypothesis should be tested by an
experiment in which the independent variable is
changed.
 The variable that is changed or affected is called the
dependent variable, and will be measured.
 Any other variables should be held unchanged or
constant.
 An Italian physician named Francisco Redi proposed
an experiment to test spontaneous generation.
 A flask containing raw meat was left in the open. This
was the control group, since no new variable was being
introduced.
 Two additional flasks were set up, one completely
sealed, and the other covered with gauze to allow air
flow.
 These were the experimental groups that were being
exposed to the independent variable.
 The dependent variable, the appearance of maggots, was
recorded.
 Only the unsealed flask grew maggots. Redi’s
conclusion was that his hypothesis was correct -maggots did not spontaneously generate, but grew
from tiny eggs laid by flies.
 Conclusions always indicate whether the original
hypothesis is supported or rejected.
 The idea of spontaneous generation was eventually
discarded through the use of the scientific method.
 Scientific methodology involves:
 observing and asking questions,
 forming hypotheses
 conducting controlled experiments,
 collecting and analyzing data
 drawing conclusions.
 All experiments
involve the collection
of data.
 If this includes
numerical
measurements
(time, distance, etc),
the data is
quantitative.
 If this includes nonnumerical
descriptive
observations, the
data is qualitative.
 Accounting for every single variable in a
scientific study is nearly impossible. There are
many factors that can cause error or otherwise
cause an incorrect conclusion.
 Probability helps to predict the likeliness of an
experimental result occurring simply due to random
chance.
 The effects of random chance are countered with having
a large sample size in the experiment.
 Another major problem with experiments is when
scientists or patients influence the data to produce a
specific result.
 This is called bias.
 Bias is not always intentional, but must be accounted
for in the design of an experiment.
 A blind experiment prevents the experimental subjects
from knowing whether they are in the control or
experimental group.
 Eliminates the “placebo effect”.
 A double-blind experiment prevents both the
scientists and subjects from knowing which is the
control and experimental group.
 Depending on the
results of the
experiment, the
hypothesis may be
rejected or modified.
 New experiments
may be designed and
conducted until
some version of the
hypothesis is
supported.
 Hypotheses should not be confused with theories,
which are large, broad explanations composed of many
hypotheses and experimental results.
 A theory would not be rejected by a single experiment,
but a hypothesis could be.
 An example of a theory is the germ theory, which states
that some diseases are the result of the presence and
actions of microorganisms within the body.
 A scientific law is a description of an observed
phenomenon.
 Laws do not explain the phenomenon, simply state it.

1. Quietly write at least 5 sentences in your
“note journal” summarizing what you
have learned today.
2. If you finish early and have any question
for me, please write on a post-it-note and
stick it to the “parking lot”.
3. Please wait for me to dismiss the class!
You are wonderful! 
Love having you in class!
