Abstract
Activities
Conclusions
As part of a National Science Foundation program
(NSF GK-12), engineering graduate students
(Fellows) work with inner city high school
science and math students to bring current issues
into the classrooms. Fellows are initially
trained in lesson planning and other pedagogical
techniques then are teamed with volunteer
teachers from schools that were selected to
participate in the program. Fellows develop and
deliver content that links with
classroom-required curriculum, in a way that
authentically teaches science, technology,
engineering and math (STEM) skills. This
interaction between the Fellows, high school
students and secondary school teachers enriches
all three perspectives and helps prepare Fellows
for possible faculty positions. Over the course
of a school year, a series of lessons was created
by an NSF GK-12 Fellow and taught in a Cincinnati
public school 10th grade biology class. Topics
covered included formation of the atmosphere
(biogeochemistry), global water and carbon
cycles, climate change, air pollution, health
effects of criteria pollutants, and the impacts
of transportation options on the environment,
equity and the economy (sustainability). The
Fellow taught a related unit in their math class,
applying basic statistics to the prediction of
health effects and control of pollutants.
Effectiveness measures included pre and post
tests, surveys, graded class work, homework, and
other assignments. Results included higher
scores for the students and greater interest in
engineering. The lessons also gave them facts and
broader scientific perspectives on topics that
have recently been highly publicized, equipping
them to be more discerning citizens. Most
importantly, the series showed the
interrelatedness of natural and anthropogenic
influences on climate and discussed the impacts
of personal choices.
- Lessons comprise a module taught over 15 days,
spread over a four-month period, to two classes
of 10th graders, roughly 40 students. The lessons
incorporated a variety of instructional
techniques including direct and indirect
instruction, questioning, and collaborative
learning. Specific learning activities included
lectures, demonstrations, labs, videos guided
with a worksheet of data to gather from the
video, field trips with a worksheet of questions
to answer, and more. Details about the STEP
program, including lesson plans for the
activities is available after the end of the
school year at http//www.eng.uc.edu/STEP. For
all lessons and field trips an attempt was made
to integrate math and science, to weave in
real-world applications and examples, and to link
the concepts to local Cincinnati situations.
Information about college educational
requirements and careers in science and
engineering, plus examples from the Fellows
experiences as an engineer were liberally
sprinkled through these lessons and other class
interactions during the year. - Major components of this series included
- Earth History Formation of the earth, its
oceans, and atmosphere plate tectonics origin
of major life forms ice ages esp. impact of
glaciers in Ohio climate variations and
predictions for future supercontinent formation
and climate. Students created a timeline of Earth
history and took a quiz on lesson content. - Living in a Greenhouse evaporation,
condensation, dispersion, thermal inversions,
carbon and water cycle review, GHG types and
sources, IPCC predictions, climate models,
potential effects in Cincinnati, sustainability,
actions we can take to minimize GHGs - Skittles Statistics colored candies represented
contaminant level in environmental samples,
statistical properties and plots of data sets,
acute and chronic toxicity, predicting health
outcomes - Health Effects of Air Pollutants demonstration
of CO2 formation through human respiration, lab
where students constructed a spirometer and
measured their vital lung capacity, respiratory
system functions, criteria pollutants and
sources, AQI, Cincinnati air quality data - Carbon Footprint/Sustainable Transportation
measuring particulates around school,
representing data on maps and with plots,
correlating particulates with sources, comparison
of impacts of transportation alternatives (bus,
car, bicycle, walking) and sustainability
implications of transportation choices.
Average improvement in class scores for
individual students who took all pre and post
tests was 65. Not all students took both the
pre and post test. A total of 40 students
participated in the lessons. Total average
improvement in class scores for series was 90.
The lessons were effective in increasing their
knowledge of the information, and (perhaps most
importantly) in increasing students confidence
in their abilities to learn science and math.
Total positive reports for this metric were 70.
The students were also interested in engineering
following the lessons. A total of 84 reported
being very or somewhat interested. Roughly
45 reported that the lessons had increased their
interest in engineering (data not shown here).

Educational Goals and Objectives
- This was an original series of lessons.
Individual lessons incorporated information from
a variety of sources, including - How the Earth Was Made (History Channel, AE
Television Network, New York, NY, 2007) - The Greenhouse Effect (Films Media Group,
Cambridge Educational, Princeton, NJ) - USEPA (numerous portions of website www.epa.gov
and several publications) - Teays River Fact Sheet, Ohio Department of

Specific objectives relating to the Ohio
mathematics and science standards and benchmarks
for 10th grade level were set for each lesson.
Another constraint was meshing with the classroom
teachers course content maps for the academic
year, which included preparing the students to
take a standardized state test. Additional
personal objectives of the Fellow were to help
create scientifically literate citizens, and to
dispel fear about the potential impacts of global
warming.
Humans create anthropogenic intersections of the
carbon and water cycles.
State Standards
- Over the course of these lessons, more than 17
Ohio science benchmarks from all 6 science
standards, and 13 Ohio math benchmarks from 4 of
the 6 math standards were addressed. Several of
the standards were covered repeatedly and from
different perspectives and in different
applications. Standards addressed included - Science Standards
- Earth and Space Sciences
- Life Sciences
- Physical Science
- Science and Technology
- Scientific Inquiry
- Scientific Ways of Knowing
- Mathematics Standards
- Number, Number Sense and Operations Standard
- Measurement Standard
- Data Analysis and Probability Standard
- Mathematical Processes Standard
