Transcript (power pt) Inquiry Science

INQUIRY SCIENCE
a year long, one (lab) credit, science course
for sophomores at
Tahoma High School
begins with
The Scientific Method
through the lens of
Microbiology:
The study bacteria & viruses
First, you need
which
aka
means
a TESTABLE
it is… measurable
question
Once you’ve decided on your
question, design/carry out
your experiment
paying close attention to its
validity & reliability
Recognizing that the process
of scientific investigation is
CIRCULAR
(“non-linear “… a neverending process!!)
SUPPORTED
by
data
CONTRADICTED
NOT SUPPORTED by data
Following in the footsteps of
Ignaz Semmelweis,
Tahoma Investigation:
But WHY Herr Doktor, must
ve vash our handz before
every surgery!????
Where,
on campus,
do microbes
THRIVE!?
CHAPTER 1 Major Concepts
MC #1
Scientific investigations include...
-a testable question
-a design that leads to valid and reliable results (conclusions)
-observations and measurement
-an appropriate way of communicating and defending a scientific
argument
MC #2
Scientific inquiry is a systematic, nonlinear process that increases our
chances of solving certain types of problems
The remainder of 1st semester will focus on answering one question…
where
did I
come from?
Chapter 6…
Every branch of science has its “GUT”
EVOLUTION
GRAND
Geology has the Theory of Plate Tectonics
Physics is working on its String Theory
& Chemistry has the Molecular Theory
UNIFYING
but Biology has the Grandest GUT of them all…
THEORY
THE THEORY WITH MORE SUPPORTING EVIDENCE
THAN ANY OTHER THEORY IN THE HISTORY OF MAN!!!
For example, let’s begin with…

Leads to

And
It
Starts

The HMS

the voyage
of
Charles Darwin
Geologic
Time & the
History of Earth
And so much more evidence!!...but that will require additional chapters…
CHAPTER 6 Major Concepts
Evolution explains the diversity of life on earth;
1) organisms change across time
2) natural selection explains how species change (across time)
3) multiple lines of evidence confirm evolution
4) physical properties (of the earth) change (across time)

CHAPTER 7: Basic (Mendelian)
Genetics
Which
color
pea is
recessive?
Non-Roller
Down’s
Syndrome
Tongue-Roller
Chromosomes
Genes
& Karyotypes
Which is DOMINANT?

CHAPTER 7 Major Concepts
Traits are transmitted from parent to offspring through
gametes
Meiosis results in the formation of gametes that contain half
the genetic information of other cells
Cells contain two copies of each chromosome and therefore
two copies of each gene
Variations in the traits of different generations are explained
by the fact that each individual gets two copies of each gene

Which is made of…

DNA sequencing technologies
And finally, the
most powerful,
most convincing
EVIDENCE of
biological
evolution ever
discovered…
CHAPTER 8 Major Concepts
DNA is found in all living things and carries the genetic code
for their characteristics
DNA can replicate to pass its genetic information to new cells
DNA serves as a template for making proteins
Proteins are substances essential to life
Mutations in DNA result in changes in proteins that can be
advantageous, neutral, or detrimental to individual organisms
(and their species)
Similarities in DNA (or amino acids) show relatedness of
organisms
Just because
we can,
SHOULD we?
And if we don’t,
what’s to stop
your
competition?

Environment…

Concepts
Chapter 11: Carbon on the Move
And witness the
consequences
•Some substances with carbon can be analyzed with simple tests
•Earth has a fixed amount of carbon; that moves along several main

•Carbon transfer involves chemical reactions with changes in atomic
structure and properties of the material
•Simple reactions simulate carbon cycling in nature
•Some carbon sinks in the past are now sources of fossil fuels

So we wrap up the year by providing each student with the TOOLS
to solve man’s problems…namely…
…using SCIENCE to solve problems.
But realizing…
…there’s no such thing as a “perfect” solution
(there are ALWAYS “trade-offs”)…
…and there are ALWAYS unintended consequences
That being said…how did Greensburg, Kansas decide to
“engineer” its future?
