In this activity, students construct their own rocket-powered boat called an "aqua-thruster." These aqua-thrusters will be made from a film canister and will use carbon dioxide gas produced from a chemical reaction between an antacid tablet and water to propel it. Students observe the effect that surface area of this simulated solid rocket fuel has on thrust. Less

Students learn about the wonderful and fascinating country of China, and its environmental challenges that require engineering solutions, many in the form of increased energy efficiency, the incorporation of renewable energy, and new engineering developments for urban and rural areas. China is fast becoming an extremely influential factor in our world today, and will likely have a large role in shaping the decades ahead. China is the world's largest energy consumer and the largest producer of carbon dioxide emissions, leading engineers and scientists to be concerned about the role these emissions play in rural and urban public and environmental health, as well as in global climate change. Through exploring some sources of air pollution, appropriate housing for different climate zones, and the types of renewable energy, the lessons and activities of this unit present ways that engineers are helping people in China, using an approach to cleaner, smarter, healthier and more-efficient ways of living that apply to people wherever they live.

The module illustrates the typical synoptic pattern influencing fire weather in southeast Australia. A case study provides insight into how experienced forecasters combine the four key ingredients—wind, temperature, dew point temperature, and fuel state—to produce a fire danger index value and resulting forecast policy map. Then, a case exercise allows the learner to practice using weather and fuel data to create a fire weather forecast policy map for southeastern Australia. Less

In this activity, learners will be introduced to biomass gasification and will generate their own biomass gases. Learners generate these gases everyday on their own and find it quite amusing, but this time theyäóťll do it by heating wood pellets or wood splints in a test tube. They will collect the resulting gases and use the gas to roast a marshmallow. Learners will also evaluate which biomass fuel is the best either according to their own criteria or by examining the volume of gas produced by each type of fuel. Less

In this two-part activity, learners work in pairs to examine the four basic stages of a turbine engine. During the first part of the lesson, learners visit three stations: Combustion, Compression, and Intake to discover what happens as different forces act on air. In the second part, learners build a model of a turbine engine. This activity emphasizes the scientific method including prediction, observation, data collection, and analysis. This lesson plan includes instructions on how to set up the stations, discussion questions, diagrams, black-line masters, and sample worksheets for learners. Less

Ethanol is a clear, colorless liquid that has a very distinct alcohol smell. It was discovered/made as far back as 6000 B.C. in the production of beer and wine. The Chinese were the first to distill it from fermented rice liquor. It is fermented from glucose sugars of plant cell walls. Ethanol is the primary ingredient in alcoholic beverages and is a central nervous system depressant in humans. It is absorbed in the gastrointestinal tract and reacts violently with oxidants. Henry Ford used ethanol to run the first engine for the Model T. Currently, there is a lot of research related to increasing use of ethanol as a fuel to help the environment and offset the demand of oil since it burns much cleaner than oil and is a renewable resource. Ethanol is commonly used as a disinfectant; it kills organisms by denaturing their proteins and dissolving their lipids: it is effective against most bacteria and fungi, and many viruses, but is ineffective against bacterial spores. This disinfectant property of ethanol is the reason that alcoholic beverages can be stored for a long time. Less

In England in 1661, Irish chemist Robert Boyle discovered methanol as a byproduct of the distillation of wood, hence the archaic names, spirit of wood and wood alcohol. Methanol is a clear, flammable, and toxic liquid that can cause blindness if repeatedly inhaled or ingested. Consumption (>2 Tbsp) can be fatal, but the body can metabolize small amounts. Methanol is prepared by the catalytic combination reaction of carbon monoxide and hydrogen gases under high pressures. It is used in fuel mixtures to stretch the life of gasoline, in addition to its use in windshield washer fluid (50% MeOH) and paint strippers. Also methanol is used as industrial solvent in manufacture of streptomycin, vitamins, hormones, polymers and plastics. Less

Propyne, also known as methyl acetylene and allylene, is a colorless, non-toxic gas. It is flammable at room temperature and atmospheric pressure with a characteristic sweet acetylenic odor. Since it is heavier than air and may travel along the ground (like ether) and distant ignition is possible. Propyne is the second simplest member of the acetylene family. It can form explosives mixtures with air and oxidizing agents. It is used as welding torch fuel. Propyne has been identified in the atmospheres of outer planets and in interstellar clouds. Less

Propane, one of the simplest alkanes with three carbons and eight hydrogen atoms, is a colorless gas used in many home appliances e.g., grills. It is a hydrocarbon produced from crude oil and natural gas, which has been one of the successful alternative transportation fuels. The advantages of using propane as a fuel are lower maintenance costs, fewer spark plugs and oil changes, and less wear on such components as piston rings and bearings. Also, vehicle emissions from natural gas and propane are expected to be lower and less harmful to the environment than those of conventional gasoline. In the petroleum industry, propane is used as a combined solvent and refrigerant for the refining of lubricants and other products. Less

There is tremendous potential for the United States to forge new political alliances at home and abroad in the production of ethanol. At the same time, decreasing dependence upon petroleum will also have consequences. The relative benefits and disadvantages—political, social, economic, and environmental—must be weighed carefully by those who are in the position of crafting and implementing national policy. Less
