A Study of Alternative Fuels

Photo shows a red tractor with a 7-blade plow attachment working through a green field. In the middle of the attachment a red hose lays out in the field.
Lesson 1: Creating an Electromagnetic Field

Student teams will work together to discover properties of electromagnets. They will work together to create their own electromagnets and experiment its strength to pick up paperclips using batteries of varying voltages. With this experiment, they will also learn about series and parallel circuits. Later lessons will require the use of these electromagnets to create a hand-built electric motor.

Lesson 2: Creating an Electric Motor

Students will discover some properties of electromagnets. They will create their own electric motor and measuring its torque by picking up a weight over a given distance and time. With this motor, they will learn how an electric motor works and to troubleshoot for optimum operation.

Lesson 3: Creating a Hydrogen Generator

Students will discover some properties of Hydrogen. They will work to create their own hydrogen generator and experiment by measuring its gas production and amperage used for production.

Lesson 4: Hydrogen Cars

Students will discover some properties of Hydrogen and how a PEM (Proton Exchange Membrane) operates. They will work to create their own hydrogen kit car and experiment by measuring its gas production, power output if the fuel cell, and the power requirements for operating the vehicle for one minute.

Lesson 5: Creating a Hydroelectric Powerplant

Students will discover a relationship between amperes and voltage to Watts as a hydro-electric powerplant produces electricity. They will work as a team to create a powerplant and measure the flow and force of electricity. The variables of air pressure will simulate different head pressures as it pertain to simple water dam design. They will compare their results to power requirements of various, everyday appliances.

Lesson 6: The Cycle Analyst

Students will use a Cycle Analyst to collect data from an electric go-kart and measure the efficiency of the system. The Cycle Analyst can be used on other small electric vehicles such as electric bicycles, scooters and golf carts.

Lesson 7: The Farmer’s Dilemma

Over the course of the previous six labs, the students are exposed to alternative power systems focusing on hydrogen and electricity. This last structure combines all the knowledge students armed themselves with into a comprehensive presentation regarding the future of farming in our area… specifically that of fuels the farm tractor will use to harvest crops. The intent is for the student to become knowledgeable about the pros and cons of various alternative and conventional fuels systems. The students will pair up to present one of several points of view regarding a fuel system whether it be alternative or conventional.

7 Lessons / 20.5 - 26.5 Hours

Through a series of alternative fuels labs, students will learn the basic principles of energy conversion and use via electrical and hydrogen labs.
Students will wrap up all of their labs with a final AVID-style Philosophical Chairs designed debate regarding alternative fuels pro and cons, environmental issues, and how our local farmers will face the upcoming conventional fuel ban on new vehicles.
