Define the criteria and constraints of a design problem with sufficient precision to ensure a successful solution, taking into account relevant scientific principles and potential impacts on people and the natural environment that may limit possible solutions.
Evaluate competing design solutions based on jointly developed and agreed-upon design criteria using a systematic process to determine how well they meet the criteria and constraints of the problem.
Analyze data from tests to determine similarities and differences among several design solutions to identify the best characteristics of each that can be combined into a new solution to better meet the criteria for success.
Develop a model to generate data for iterative testing and modification of a proposed object, tool, or process such that an optimal design can be achieved.
Write informative/explanatory texts, including the narration of historical events, scientific procedures/ experiments, or technical processes.
Use precise language and domain-specific vocabulary to inform about or explain the topic.
Produce clear and coherent writing in which the development, organization, and style are appropriate to task, purpose, and audience.
Use technology, including the Internet, to produce and publish writing and present the relationships between information and ideas clearly and efficiently.
Engage effectively in a range of collaborative discussions (one-on-one, in groups, and teacher-led) with diverse partners on grade level topics, texts, and issues, building on others’ ideas and expressing their own clearly.
Present claims and findings, sequencing ideas logically and using pertinent descriptions, facts, and details to accentuate main ideas or themes; use appropriate eye contact, adequate volume, and clear pronunciation.
Include multimedia components (e.g., graphics, images, music, sound) and visual displays in presentations to clarify information.
Adapt speech to a variety of contexts and tasks, demonstrating command of formal English when indicated or appropriate
The point in a rocket around which its weight is evenly balanced; the point at which a model rocket will balance on a knife edge.
The point where the total sum of air pressure forces act on a body.
The aerodynamic force that opposes an aircraft’s motion through the air.
The stabilizing and guiding unit of a model rocket (which should be in a symmetrical form of three, four, or possibly more and made of reinforced paper, balsa, or plastic); an aerodynamic surface projecting from the rocket body for the purpose of giving the rocket directional stability.
Force that pulls everything down toward the center of the Earth.
The force that directly opposes the weight of an aircraft and holds an aircraft in the air.
The amount of matter in an object
The foremost surface of a model rocket, generally tapered in shape to allow for streamlining, usually made of balsa or plastic.
A stable and safe rocket where the nose of the rocket travels forward and moves in a predictable flight path. For a stable model rocket, the center of pressure should be located below the center of gravity.
The propulsive force that moves something forward.
