Earth Science Unit 1
Introduction and Mapping Skills
Suggested Time: 3 Weeks
During this unit, the students will gain an understanding of the scope of earth science as a survey
of astronomy, meteorology, geology, and oceanography. In addition, it is very important that
students review the scientific method that has been emphasized during their prior science
experiences and plan and conduct scientific investigations using inquiry methods and skills.
They should learn the importance of data collection and the analysis of data through practical lab
experiences. Students should gain experience in using metric units of measure and graphing
data. Safety rules and skills should be introduced in this unit and infused throughout the year.
The second part of this unit gives the students an introduction to mapping. Students will learn
how to read and interpret maps, globes, charts, and imagery. A review of cardinal direction, map
scales, map legends, and latitude and longitude are essential. Time measurement is taught in this
unit but is not a skill that is tested on the VA SOL test in earth science.
A performance assessment on scientific investigation and mapping should be introduced early in
this unit so that students may work on it throughout the unit. The resource is Performance
Assessment in Earth Science – Unit 1 from the Glencoe supplement entitled Performance
Assessment in Earth Science, pp. 1-4. Teachers should familiarize themselves with this activity
before planning the unit.

Scientific investigations require standard measures
and consistent, reliable tools.
Information and data collected can be organized and
expressed in the form of charts, graphs, and
diagrams.
Modern instrumentation for data collection includes
probeware interfaced to computers or graphing
calculators, digital cameras with imaging software,
and global positioning systems (GPS).
It is necessary to devote time and mental energy to
carefully study data for relationships and patterns.
Careful interpretation of the data allows us to more
easily defend our findings.
Experiments are designed to test hypotheses.
Hypotheses are tentative explanations that account
for a set of facts and can be tested by further
investigation.
Any valid hypothesis can be tested.
Hypotheses can be supported, modified, or rejected
based on collected data.
Changing relevant variables will generally change
the outcome of an experiment.
Conclusions are only as good as the quality of the

to validate it. Maps are drawn to scale. Scale relates
to actual distance and indicates how the map’s
features compare in size with Earth’s surface.
Distances on a map are determined by using a
variety of scales.
Symbols are used on maps to represent physical
features such as rivers, lakes, mountains, or plains.
Symbols can also be used to represent human-made
features such as highways, cities, or airports.
A map legend, or key, is a list of symbols used on a
map and an explanation of their meaning.
The locations of places on Earth are pinpointed
through a grid of imaginary lines on maps and
globes known as latitude and longitude. Latitude
determines a location by measuring north or south of
the equator. Longitude measures east or west of the
Prime Meridian.
Topographic maps relate to actual 3-D landforms,
both natural and man-made. Contour lines on
topographic maps show slope and elevation.
Time zones are based on location and influence
global communication and travel.
The Global Positioning satellites orbit Earth and
send signals that can be picked up by a user’s
receiver to determine position on Earth.
Air photos and satellite images relate to actual 3-D
landforms and may show physiological features and
elevation of a particular area.
Aerial photography allows mapmakers to study
photographs of land areas and determine the
contours of the land. Satellite technology gives an
even broader view of Earth by gathering data from
broad areas of Earth’s surface.

Stage 2- Assessment Evidence
Title of Performance Assessment City Planner
Description of Assessment Task In this performance assessment, students are asked to design three different hiking trails according to specific
criteria that serve different purposes. Students will explain and defend their decision for each trail for City
Council. The performance assessment consists of two components. In part A, students create an experiment
and demonstrate understanding of SOL ES 1.a, b, c, and d. In part B, students apply knowledge of SOL ES
1.e by analyzing and evaluating map features to determine best use of area recreational use in real world
application.

Science Practices In this performance task student will define the problem (engineering) from the information City Council has
requested. By using models and computational thinking, students will have the opportunity to engage in
crosscutting concepts. Additional science practices contained in this performance assessment are:
Planning investigations
Designing solutions
Engaging in argument from evidence
Obtaining, evaluation, and communicating information
4 C’s In this task, students will apply scientific principles to solve real-world problems with identified criteria
(critical thinking) with peers (collaboration). Students will also construct their defenses for City Council in
writing (communication) as well as construct a trail that follows recommended sustainability guidelines
(creativity).
Assessment Outcomes/Performance Expectations Analyze topographic maps
Create a topographic profile between two points on a map
Determine the distance between two points on a map using the scale
Interpret landforms, water features, map scale, horizontal distance between points, elevation and elevation
changes, and human made structures
Determine what data needs to be collected based on investigative questions
General Teacher Instructions Teachers should allow one to two blocks (90-180 minutes) for students to complete the assessment. Students
may work in groups. It is recommended that homogeneous grouping of 2 to 3 students be used. Prior to
students working on the assessment, teachers should spend a few minutes discussing the performance
expectations and the rubric. Students will need to be familiar with how to read a topographic map and how to
use a map scale and compass rose, basic knowledge of topography and topographic contours and know how
symbols are used on topographic maps. Student products will contain a plan for analyzing soil and a written
explanation for part A and a data sheet, correct profile, and trails added to the map for part B. Teachers may
modify the task or break the task into smaller chunks to be assesses at various points in the unit. It is
recommended that students and the teacher conference often throughout the assessment with students taking
feedback into account before turning in the final product.
Calibration for Scoring Student Work and Examination of Data
Scoring performance based assessments should occur in PLC’s. Research shows that when teachers “use,
score, and discuss results of high-quality performance assessments over time, both teaching and learning
improve” (Darling-Hammond, 2014, p. 11). It is recommended that teams follow the Team Protocol for
examining data found on the Secondary Science SharePoint site. A summary is also included below.
One person serves as the facilitator and shares an overview of the process.
Each team member is given 5-7 minutes to look over a sample of student responses (teachers may choose to look
over 3 or 4 very strong responses and 3 or 4 weaker responses). Each team member reflects on the following and
then shares their thoughts with the group:
o I wonder if…
o I predict that…
o Some possibilities for learning that the data might offer are…
After all members have shared their thoughts, they are provided 8-10 minutes to jot down their observations:
o What do you observe in the responses?
o What important points in the responses initially “popped out” at you?
o What patterns or trends did you notice?
o What surprising or unexpected features are present in the responses?
The team shares their responses to the above questions for 5-10 minutes.
The team chooses three student responses to evaluate as a team. Each teacher evaluates the responses based on
grading criteria established and provided in this document for 5-10 minutes.
Each team member takes turns discussing each responses, how the response was evaluated, and why. The team
discusses any discrepancies in grading and decides on how the performance assessment task will be evaluated. The
purpose of this step is to overcome rater bias.
Next, teachers grade their student’s responses and bring data to the meeting on a different date.
On the second meeting, teachers discuss the results. Teachers are provided with 5-10 minutes to reflect on the
following question: “What are the implications for teaching, learning, and improving student achievement in the
area(s) we have been examining?” The purpose of this step is to make connections between what needs to be done,
what should be changed, and what is working. The following questions should be taken into account as team
members individually record their ideas:
o What have we learned from the data?
o What steps should be taken next?
o What are appropriate strategies or solutions that will address the needs implied in the data?
o What does the dialogue make you think about in terms of your own practice?
o In what areas should we change what we are doing?
o What other data or information would help us determine if our solutions are working?
After individual think time, the team engages in dialogue for 10-15 minutes in which all members share their
thoughts. Each idea is considered and recorded on chart paper.
Team members take another 5-10 minutes to form consensus on one or two major issues identified and one or two
strategies to address these issues. The team also decides upon the method(s) to be used to assess whether the
strategies have successfully addressed the issues.

City Planner Performance Assessment
Trail design is one of the most important factors to insure that the route offers optimum scenic, geologic,
historic, cultural and biological sites to provide a variety of diverse habitats for the trail user to experience.
Trail design is the critical connection to make the trail sustainable, to reduce impacts to the natural
environment, and to minimize future trail maintenance. City Council has requested that you plan three hiking
trails, each with a different difficulty level in the Campedo community. Most visitors to the mountain like to
camp and hike from the camp site. City Council has given you several criteria that must be followed to
develop the trail system. Your success as a planner depends on the attention to detail you use. Read through
all of the parts before proceeding.
PART A:
City Council will require answers to the following questions so be prepared to write a written response to the
council before the presentation: 1. Scientists describe soil based on color, texture, and consistency. You will need to create an experiment so that
you may use the data from soil test to identify the soil type (you will not need to carry this out until the plan is
approved but council will ask you to provide them with a plan on what data you will need to collect, how, and
why).
2. Where is it easiest to build the hiking trails and why? What areas are unsafe and why?
3. Justify why you decided to create a hiking trail at each location.
4. What did you have to take into account when you planned the hiking trails?
PART B:
All trails must meet the following criteria:
Easy access from a camp site and be connected to at least one other camp site
Be connected to at least one existing trail
A data sheet describing the length of trail and any other interesting features
Begin and end at the same camp site
Correct profile between the camp site and the farthest point on the trail
Determination of which trail surface will be used with a justification supporting the use of the surface including
total cost per trail. (use the alpa planning and design tool: http://atfiles.org/files/pdf/AltaTrailSurface.pdf)
Be sustainable as described by the National Park Service:
o Supports current and future use with minimal impact to the area’s natural systems.
o Produces negligible soil loss or movement while allowing vegetation to inhabit the area.
o Recognizes that pruning or removal of certain plants may be necessary for proper trail construction and
maintenance.
o Does not adversely affect the area’s wildlife.
o Accommodates existing use while allowing only appropriate future use.
o Requires little rerouting and minimal trail maintenance.
Level 1 trail needs to include the following:
Wheelchair access
Be no longer than 3 Km
Be paved and have rest stops with benches no farther than .5Km apart
Level 2 trail needs to include the following:
Be no longer than 6 Km
Be a looping trail
Level 3 trail needs to include the following:
Be between 6 and 18 Km
Contain a significant increase in elevation
Your responses (on a separate sheet):
1. List all action items City Council has requested of you:
2. Construct a plan for each action item and write a detailed justification for City Council.
3. In different colors, add the trails to the map. Be sure to add this to the key.

Introduction to Data Collection
Data collection is a very important part of science. Meteorologists collect weather data over time to keep an historical record and to help make forecasts. Oceanographers collect data on the salinity (saltiness) of seawater to study changing trends in our Earth’s oceans. While data have been collected by hand for thousands of years, the technology to collect data electronically has been around for fewer than 80 years. Only in the last 20 years has this technology been available to schools.
This experiment was designed to introduce you to two of the most common modes of data collection that will be used in this class. Part I will guide you through collecting and analyzing data over time. A Temperature Probe will be used to record the temperature of water for 60 seconds at a rate of one sample per second. In Part II, you will collect data using a mode called Events with Entry. This style of data collection allows you to collect one point of data, then will ask you to enter a corresponding value. In this experiment, the data collected will be the temperature of your hand and the value you enter will be your assigned group number.
OBJECTIVES
In this experiment, you will
Become familiar with the Data Pro program. Use a handheld and a Temperature Probe to make measurements. Analyze a graph of the data. Use this graph to make conclusions about the experiment. Determine the response time of a Temperature Probe.

Where IS North?
It depends. Do you mean geographic north or magnetic north? The geographic (true) north pole is the point at 90o N latitude. It is aligned with the rotational axis of the Earth. The Earth is surrounded by a magnetic field with a north and south magnetic pole. The magnetic north pole is the point to which a compass needle points. It is currently in northern Canada, but moves at an average rate of 15 km per year due to complex fluid motion in the outer core of Earth. Depending on your location, the difference between magnetic north and geographic north, called magnetic declination, can range from 0o to 30o.
Similar to a bar magnet, the Earth is surrounded by 3-dimensional magnetic field lines. The field lines of the Earth start near the south pole, curve around in space and converge again near the north pole. A compass needle aligns itself along the direction of the magnetic field lines. Magnetic inclination, or dip angle, is the angle that the Earth’s magnetic field makes with the horizontal plane at a specified location. Magnetic inclination is 0o at the magnetic equator and 90o at each of the magnetic poles.
The Earth’s magnetic field is used by many animals to determine direction. Every location on Earth has its own unique combination of magnetic field intensity and inclination. The Loggerhead turtle detects magnetic field intensity and magnetic inclination and uses this information on its 10 year migration around the Atlantic Ocean. Many birds use both stars and the magnetic field of the Earth to navigate. The birds can detect magnetic inclination. Birds in the northern hemisphere follow a line of decreasing dip angle that guides them on their southerly migration path.
In Part I of this experiment, you will measure the magnetic field of the Earth. You will use this data to determine magnetic north. Knowing the direction of true north, you will calculate the magnetic declination at your location. In Part II you will measure the magnetic inclination of your location.
OBJECTIVES
In this experiment, you will
Use a Magnetic Field Sensor to measure the magnetic field of the Earth. Calculate magnetic declination for your location. Measure the magnetic inclination of your location.

Magnetic inclination (o)
PROCESSING THE DATA
1. The difference between the measured magnetic north and true north is called magnetic declination. What is the magnetic declination for your location? What modifications would be needed on a compass in your location to keep you on course when following a map?
2. How does the measured magnetic inclination compare with the accepted magnetic inclination for your location?
3. Scientists have found that the magnetic field of the Earth is continually changing. What
would be the implications of a big change?
EXTENSION
1. Compare the magnetic declinations of various locations on your continent and discuss the adjustments needed on a compass at each location to stay on course.
2. Research current theories on why the magnetic north pole moves.

Combining Latitude and Longitude
In order to give the exact location of a place on earth, we must use both latitude and
longitude. We must tell how far east or west it is, as well as how far north or south. We can
do this more easily by combining the lines of latitude (parallels) and the lines of longitude
(meridians), which form a pattern called a grid.
Below is a map of the original thirteen colonies. Use the grid to identify the colony in which
each of the following points is located. Sometimes you must estimate.

TIME ZONES
PURPOSE: Label the 24 Standard Time Zones on a world map and use time zones in North America to
determine variations in dates and hours from place to place
BACKGROUND: The earth rotates 360
These time meridians, beginning with the Prime Meridian, mark the centers of the 24 standard
time zones. This is a man-made system designed for convenience although it is based on earth
movements. Consequently, the time zone boundaries are often altered to conform to political
divisions or natural features.

Time Zones of North America Map
DIRECTION: 1. Label the world map, Standard Time Zones.
2. Notice the dotted longitude lines. These are the time meridians. Beginning with 0
Prime Meridian which passes through Greenwich, England), label the time meridians.
3. As one advances eastward toward the International Date Line, one hour is gained in each zone.
In the boxes at the lower edge of the map indicate the increase in hours from Greenwich.
2+ 1+ 0

4. As one advances westward from Greenwich to the International Date Line, hours decrease.
Label the boxes accordingly.

5. Interpret the world map.
a. If it is 7 a.m. Tuesday in Greenwich, what time and day is it in Bombay?
b. If it is 10 p.m. Tuesday in Greenwich, what time and day is it in Bombay?
c. If it is 2 p.m. in San Francisco, what time is it in Honolulu?
d. If the time is 12 noon in Honolulu on Sunday, what is the time and day in Sydney?
e. What happens to the date when we cross the Date Line?
f. The International Date Line is not a straight line. Often time zone boundaries are slightly
irregular in shape or slightly off of the time meridians. Why?
6. Look at the map, Time Zones of North America.
a. In which hemisphere (by longitude) is this map located?
b. How many standard time zones are across North America?
c. Name from east to west the time zones of the continental United States?
d. In which time zone do we live?
e. What other countries are parts of our time zone?

Build Your Own Topo Map
Purpose: To read directions and build a topography map.
Procedure: 1. On a sheet of paper, construct a square that is 18 cm on each side and divide it into 36 equal sections. I did it
for you :)
2. Lightly pencil in the sections numbers as shown:
6 5 4 3 2 1
7 8 9 10 11 12
18 17 16 15 14 13
19 20 21 22 23 24
30 29 28 27 26 25
31 32 33 34 35 36
3. With a blue pencil, draw a river winding through sections: 4, 9, 15, 23, and 24.
4. Draw and label the contour lines with these specifications:
a. The highest part of the map is 700 feet in sections 6
b. The contour interval is 20 feet
c. The land slopes gently down to the southeast with the lowest elevation
5. Using the correct symbols place the following objects where they would go on the map.
A Primary highway running north to south form sections 5 through 32.
A Secondary highway running east from the Primary highway across sections 20 and 21 and to the center
of 22.
Then this Secondary highway veers northeast through 14 and 12.
An unimproved road running south from the Secondary highway in section 22 down through 27 and 34.
A single track railroad running diagonally across the map from 19 to 12.
Three houses along the west side of the highway in section 8,
A cemetery on the east side of the highway in 17.
A small lake in 31
Two houses with a trail between them in 23.
A swamp covering most of sections 1, 2, and 3.
A school along the east side of the road in 27.
Two depressions, one in 35 and one in 36.
Answer these questions on the back of the map:
1. How do you draw the contour lines when they cross a river?
2. If this map was an actual place, where else would you need a road?
