Complete your responses in a
color other than black or red
Part 1: Describing objects in words and drawings
1.
Describe your rock/mineral here using words.
The rock I decided to go with was in the conglomerate bag. I don’t believe it is a conglomerate rock after
doing and looking up the conglomerate rock online images. This rock measures 3cm in width being the
longest and 2cm being the shortest with a height of 2.5cm. The visual description of the rock is a multiple
of various colors from gray tones, beige tones, and black tones. There is rock particles that do fall off as I
am examining the with my hands. The particles that are being release look like tin foils. The texture is
rough to touch. Rock reminds of a mountain I have climbed before.
2.
Insert your drawing of your rock/mineral:
3.
Insert a photo of your rock/mineral here:
Picture will be attached through canvas
4.
Describe what you can see through the microscope in detail,
without naming the item
.
5.
Insert a picture of the item you viewed through the microscope here:
Part 2: Looking at Landscapes
Describe the two landscapes here.
In the Matterhorn you can see a sharper peak compared to the Popocatepetl. The Popocatepetl is more like a
volcano as you can see white cloud like smoke on the top of the mountain and the Matterhorn peak is similar
to that of a pointy cone. Both seem to be have been taken place during the winter because of the snow that
covers both. In picture 1 you can see the color of the trees are more of a burnt born as if the snow had caused
some change in color. The color of the pasture is not bright green but more tannish. In picture 2 you can see
the pasture color more greener with what look to be lambs eating pasture. Sky color in both are blue with
picture 2 being covered with white clouds spread out.

Part 3: Quantitative descriptions
Graphs
1.
Describe the graph. What variables are depicted on the x and y axis? What are the data points that make
up the graph? On the Y axis it is the response variable (dependent variable) and on the X axis is the
explanatory variable (independent variable) On the Y axis it shows the Departures in temperature and the
X axis shows year.
2.
Interpret the graph.
Discuss the meaning and implications of the data that it shows.
Data from thermometers (red) and from tree rings, corals, ice cones, and
historical records (blue). Grey area is possible error in data. Black likes is
when it is smoothed multi-year average.
Calculations – please SHOW YOUR WORK for calculations
1.
The rocks along the San Andreas Fault are moving 3.4 cm per year. At this rate, how long will it take
San Francisco (on the Pacific side of the fault) to travel the 650 km to reach the Oregon border (on the
North American side of the fault)? Please show your work.
The time it will take San Francisco to reach the Oregon border is 19,117, 647
Distance = 65,000,000km
Rate=3.4cm
2.
Which is closer to you right now, the outside edge of the atmosphere (Kármán line) or the center of
the Earth? (Look it up.)
How many times
closer? Please show your work.
The Karman like is 62 miles
The center of the earth is 3,959

3.
A mountain stream is 30 km long, starting way up at 2000 m above sea level and ending at 700 m
above sea level where it joins the main river.
o
What is the average slope of the stream bed? (To get the stream's slope, aka
gradient
, divide
the vertical distance by the horizontal distance.) Please show your work.
The average sloe of the stream bed is 0.043
1,300 / 30,000km = 0.043
o
Bonus question: What is a stream bed that steep likely to look like -- is it mostly covered with
sand, pebbles, or boulders? A stream would be likely to be boulders.
4.
Fossils of a particular species of dinosaur are found in rocks between 71.5 and 70 million years old.
o
For how long did that species exist? Please show your work.
71.5 minus 70 = 1.5
o
Is that estimate a minimum or a maximum? Explain your answer.
It is a minimum of what we know now.
o
Is that an unusually long or short time for a large animal species to last, or is it about average?
Explain your answer. It would be an average.
Part 4: Science Practices
1.
Which Science and Engineering Practice(s) did you use most in this lab? For each SEP you list, give an
example of when or how it was used.
The SEP used using mathematics and computational thinking. One
example would when dividing rise over run to get the slope

2.
Which of the other Science and Engineering Practices do you think could help students understand the
content in this lab? Obtaining, evaluating and communication information could be helpful for students to
understand content in this lab.
3.
Which of the Science and Engineering Practices are you surprised to find on the list (of 8 SEPs)? Why do
you think they are included? Engaging in argument from evidence is the SEP I found surprising because
of the engaging in argument from evidence. I believe they are included because of how we would engage
from information obtained.
