In Aeronautical Engineering, hot-air balloons and various types of model airplanes are used to illustrate key principles of aeronautics and to develop associated skills. By constructing and launching hot-air balloons, engineering students understand the significance of surface area, volume, radius, and lifting force of the balloons as well as learn about the gas laws and what forces act on the balloons. They also learn how to make logic-based predictions. Then, students move on to airplanes – the basic paper airplane, balsa glider, foam wing glider, and rubber band-powered airplane. They learn about aspect ratio, stability, thrust, drag, lift, gravity, initial velocity, control surfaces, and more.
In the Surface Area and Volume activity, students use the hot-air balloons they constructed in the previous activity. Applying area estimation methods and formulas, they find the surface area of the tissue paper used to build each balloon and of the gores cut from the tissue paper. Using this information, they estimate the surface area of the assembled balloon.
Modeling each hot-air balloon as a sphere, students then calculate the volume in cubic units. They launch the balloons, recording the wind speed, outside temperature, and flight time. All the data is recorded, graphed, and evaluated.
An excellent activity for experimentation, rocketry is thoroughly explored in Aerospace Engineering. In this course, students build and launch rockets and record results from activities with four different types of rockets: fun-and-easy straw rockets, air-powered tube rockets, water-fueled bottle rockets, and solid-fuel rockets. With straw rockets, they understand center of gravity and independent, dependent, and control variables. Using air-powered (AP) tube rockets, students learn how to design a rocket experiment to achieve specific results and how to measure apogee using an altimeter. Water-bottle rocket activities help students understand how to apply basic trigonometry and to calculate apogee. Finally, students build and launch solid-fuel rockets to explore energy, ascending and descending velocity, and the process of design and documentation.
For the Computing Apogee II activity, students learn ways to calculate the apogee of a water-bottle rocket. They launch a rocket built in a previous activity several times as they stand 10, 20, 30, and finally 40 meters from the launchpad while recording the altimeter angle of each launch.
Using the recorded launch data and trigonometric functions, students calculate the height of apogee for each rocket launch.
In Air and Water, students learn about Earth’s dynamic systems of air and water. Students investigate Earth’s atmosphere, the water cycle, weather forecasting, and how water is cleaned.
DESCRIPTIONIn Air Everywhere, students study air – clean and polluted. Students also study how the air can keep airplanes in the sky.PERFORMANCE ASSESSMENT
DESCRIPTIONIn Air Power, students learn about the power of air. Students also learn that wind can push sails to make boats and cars move and that air can be compressed and used to do work. Air can make waves.PERFORMANCE ASSESSMENT
Introduce students to experimenting with variables and finding velocity with this unit on air-powered rockets. In the first section, students build simple straw rockets and test how different rocket lengths and launch angles affect flight. Students record the resulting data and use it to calculate velocity. In the second part, the class turns to rockets launched by the powerful AP Launcher. These tube rockets are ideal for outdoor or gymnasium launches that help students explore fin placement and design their own rockets. Finally, they build and launch rocket-boosted gliders.
The Varying Launch Angles activity delves into the effect of launch angles on the flight of straw rockets. After building a basic rocket, students complete two launches at a given launch angle and repeat this process while increasing the angle in increments of 15 degrees. As they work, students measure and record each launch’s flight time and range. After completing the launches, the data collected is evaluated to learn about the connection between launch angle and rocket performance.
OVERVIEWIn Alternative Energy, students explore the basic concepts of energy as well as the law of conservation of energy. Information is presented about renewable and nonrenewable energy sources and how these resource types are important for meeting global energy demands. The advantages and disadvantages of alternative energy forms such as solar, wind, biomass, geothermal, and hydropower are presented. Hands-on experiences include experiments with a wind turbine, solar cells, and hydrogen fuel cells.STUDENT OBJECTIVES
