Introduction
of FUEL-EFFICIENCY project This project is aimed for grade
level 9 to 12 students. Project Description:
plan to have the students discover the most effective means of
personal transport.?Students will study mathematical models that describe
speed, energy efficiency, and economic cost.?In addition they will use
information in the biological sciences to examine the effects of pollution
and the costs of ecologically friendly alternatives to the car.?The
students will use chemistry to explore the chemical reaction that is
the foundation of internal combustion and they will create an ecologically
safe alternative to diesel fuel.?As teachers make connections across
disciplines, the students will be more engaged and be better learners. Driving Question: How do you create an eco-friendly
mode of transportation with low cost and high efficiency? Overall goals
of the project: Our goal is to create an innovative
interdisciplinary curriculum to catalyze the learning in math and science. Project Objectives: Math:
Performance or learner

Students will be able
to: 1.
This is the first of two lesson on slope and linear equations. Student should be familiar with the idea
of slope, y- intercept , the difference between positive and negative
slope and the idea of rate of change.

Rationale ?include theoretical reasons for doing the project As America enters
the technologically sophisticated twenty first century, many leaders
in industry and education are pointing to our student deficits
in math and science knowledge.? Of great importance in our society as
acknowledged by the TEKS is the ability to read and understand graphical
data representations.?Many students and adults do not see that math
is a tool that can model reality in graphs and charts that help in problem
solving.?Ultimately, these deficits in understanding undermine our democracy
need to share information as well as our nation economic competitiveness.
Students exiting
middle schools have been turned off by math education.?While we use
manipulatives to create a visual understanding of math at
early ages, students are often turned off as we move away from the hands
on activity to the number crunching that is much of middle school mathematics.
A similar process happens in middle school science as budget cuts restrict
real-life experiments. Students are forced to deal with science as an
abstract concept, generated only in science books. At the same time
that math and science interest is waning among middle school students,
interest in cars and independence is flourishing. The National Council
for Teachers in Mathematics (NCTM) and the National Science Foundation
(NSF) strongly recommends that science and math education should be
integrated in middle and high school classrooms to give students a more
holistic experience, as is the case in reality. Our project aims to
incorporate this interdisciplinary approach by examining the biological,
chemical, and mathematical implications of fuel consumption in contrast
to available alternatives, both in the present and in the future. Our project will
leverage the interests of the middle school student in transportation
and independence by allowing them the opportunity to study current fuels
and their biological and chemical impacts on society. This is the science
component that will lay the foundation for the students?comprehension
of the economic viability and mathematical understanding of different
fuels in relation to car usage.?We will use mathematical and economic
models to explore the relative values of different forms of transportation.?Starting
with simple cost benefit analysis and graphical representation, students
will analyze different forms of transportation.?Through this interdisciplinary
approach, we hope to address real world questions about economy that
students may have while making them aware of the chemical makeup and
environmental consequences of alternative energy forms.? Background With the gas prices escalating, it reminds us the importance of alternative fuels It is necessary to have knowledge of fuel and transportation for our living, since the transportation and gas price affect our daily living. From the big environment view point, fuel economy has been a major public concern for various reasons. First, we want to reduce our dependence on imported oil and enhance the nation energy security. Second, gas vehicles also contribute to the environment pollution, greenhouse effect and ozone problem. U. S. government has put a lot of efforts to encourage the research of alternatives fuels and the production of fuel efficient vehicles. Alternative fuels include ethanol, methanol, propane, natural gas, hydrogen,
electricity, and biodiesel.?Each
of the fuels has advantages and disadvantages. All of the alternatives
have one common advantage over gasoline and diesel: They improve our
energy security because they can be made from sources other than imported
petroleum. Biodiesel: Can be produced from corn.?Can be used
in diesel vehicle only. Electricity: Can be produced from a variety of sources, include
solar an wind.?No tailpipe emissions.?Currently
available vehicles have range of less tjam
200 miles between charges. Ethanol: Can be produced from corn, sugarcane molasses, agricultural
waste, yard and wood waste, waste paper, or energy crops.?It takes 1.3
?1.5 gallons of E100 (100% ethanol) to go as far as 1 gallon of gasoline. Hydrogen: Still in the research and development stage;?not
yet commercially available; Extremely low emissions;?Can be made from
many different materials, including water, natural gas, gasoline, methanol,
ethanol, etc.; used.in fuel cells. Methanol: Can be produced from feedstock.?It takes 1.7-1.9
gallons of methanol to go as far as one gallon of gasoline. Natural Gas: It takes 3.6 gallons of Compressed Natural Gas
or 1.6 gallons of Liquid Natural Gas to go as far as 1 gallon of gasoline. Propane: Reduced carbon monoxide emissions; fossil fuel based
(refinery byproduct or natural gas reserves); non-renewable. Alternative fueled vehicles (AFVs) can run on fuels other than gasoline and diesel. Alternative-fueled
vehicles are plentiful: over 400,000 alternative-fueled vehicles are
in use in the United States and thousands are in use in other countries
as well.? Flex-fuel Vehicles can run on regular unleaded gasoline, ethanol
or methanol. Bi-fuel Vehicles can run on gasoline, diesel, Compressed Natural
Gas or Liquefied Propane Gas. Electric Vehicles offer Zero Emission, quiet, pollution-free
operation. Fuel Cell Vehicle can be fueled with pure hydrogen gas.?This
promising technology has the potential to significantly reduce energy
and harmful emissions, as well as our dependence on foreign oil. Ref: 1. http://www.state.hi.us/dbedt/ert/atfv_hi.html#anchor693131 2. http://www.fueleconomy.gov/feg/current.shtml Standards

We are committed to both formative and summative evaluation throughout the project. The objective of this project-based, collaborative learning is to increase studentsÕ achievement in math and science, and to increase studentsÕ knowledge and skills in choosing an alternative fuel to improve our living environment. Various layers of evaluation are designed throughout the project to evaluate objectives: - How is the math and science learning happened in the project? - How is this learning being applied to the real-life? - Is the project doing what it is expected? If not, why? - What outcome is to be achieved? The teacher observes studentsÕ participation and engagement, challenges with questions, interviews students for their progress. Students will use notes to record their processes and document, review and analyze their work. These works are collected to be used for the final report – writing a letter to the editor. This letter will include their learning, processes and findings from math and science aspects. Through this evaluation, we wish to increase the impact of the learning of the math and science through the understanding of the impact of the environment in our daily-life. A significant impact will then be broadly applied to the public understanding of the alternative fuel efficiency.
