Part I Qualitative vs. Quantitative,
Dimensional Analysis, and Growth
A.
Qualitative
vs. Quantitative
Two Examples of Qualitative
observations are: shapes and colors. Two Examples of Quantitative Observations
are: Numbers and Distance.
Give two
examples of qualitative observation and two of quantitative observation.
Qualitative
1. My Cell phone case has blue
flowers on it.
2. The trees leaves are changing
from Green to Red.
Quantitative
1.
My houseplant grew 3 inches this week
2.
The boy ran 3 miles on the treadmill at the gym today.
B.
Dimensional
Analysis
Question: A
four-pound bass weighs how many grams? A 4 pound bass =
1814.37 grams
4lb
÷ .0022046
= 1814.37 grams
C.
Linear vs.
Exponential Growth
You were
offered a job and your potential supervisor said, “We can pay you in two
different ways: you can earn $6.00 a day
with a $6.00 a day raise, or you can earn $1.00 a day with a 25% increase each
day. Carry out to at least 35 days
to see the characteristic patterns.
$6.00 a day with a $6.00 a day raises
Both amounts side by side
a.
Which
earning strategy is the most profitable? The $1.00 a
day rise ends up being more profitable over time.
b.
Which would
have seemed most profitable if you had stopped at six days? At six days the $6.00 a day raise seemed more profitable.
Until you reach about 20 days the $6.00 a day raise seemed like it was going to
end up more profitable.
Part II Measurements of Biodiversity, Field Methods,
Soil Testing

1.
Form your quadrant by tying the ends of your string together and forming it into a 4-meter
by 4-meter square over your area.

This exercise did not require random sampling
to chose your site. State how you
chose your site and explain any biases you discovered in yourself while doing
so. I live in an area where we have lots of open lot’s
and one happens to be right next-door. I figured this would be the best area to
conduct this experiment.

photos of the process of soil testing.

1.
Answer these
questions.
a.
What
nutrient/chemical cycles are related to soil formation? Give two specific
examples. Nutrient cycling along with nitrogen and
carbon cycling. Nutrient cycling is the cycling of a single element. The nitrogen
and carbon cycle are a chain of thermonuclear reactions in which nitrogen
isotopes are formed in intermediate stages and carbon acts essentially as a
catalyst to convert four hydrogen atoms into one helium atom with the emission
of two positrons.
b.
Why is soil
important? Soil is a mixture of rock, organic matter
air and water. It can be any type of rock; the organic matter is made up of old
plants dead animals and tiny organisms. Without the air and water tiny
organisms cannot live in soil.
c.
How is soil
type related to biodiversity and biomes? Soil has many
different organisms that interact directly with the biosphere. Because
different soils have a different ecosystem depending on climate and such this
then controls the biomes for that area.
d.
Name 3
factors that might cause soil type to change over time in short term (days to
hundred of years) or long (geologic) term.
3 factors that might cause soil to change over
time in days to hundreds of years would be; Volcano’s and Earthquakes, Erosion
from stripping the land of any vegetation it has and flooding.
