- Abstract:
-
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.

Rockets need a lot of thrust to get into space. In this lesson, students learn how rocket thrust is generated with propellant. The two types of propellants are discussed and relation to their use on rockets is investigated. Students learn why engineers need to know the different properties of propellants.

- Abstract:
-
This activity teaches combustion as the interaction of a fuel source and oxygen. A burning candle is observed, then extinguished--first by a glass cup placed over it to cut off the oxygen supply, then using carbon dioxide generated by vinegar and baking soda. Some background information is provided about how car engines use gasoline as fuel, and how humans use food as fuel-- both are similar to how the candle uses wax as fuel. The activity is written for a kit that can be checked out of the library, but the kit is not required.

-
In this activity, students investigate the simulated use of solid rocket fuel by using an antacid tablet. Students observe the effect that surface area and temperature has on chemical reactions. Also, students compare the reaction time using two different reactants: water and vinegar. Finally, students report their results using a bar graph.

- Abstract:
-
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.
