the NASA Engineering Design Challenge
This instructional unit challenges students to build a model thrust structure that is as light as possible, yet strong enough to withstand the load of a "launch-to-orbit" three times. Students first determine the amount of force needed to launch a model rocket to 1 meter, then they design, build, and test their own structure designs. In collaborative groups, they revise their designs to increase the strength and reduce the weight of their structure. Materials are all readily available at hardware stores. Allow six class periods.
Editor's Note:This module, adaptable for grades 6-10, meets a broad range of national standards. It was originally developed by NASA Design Challenge to connect students in the classroom with the challenges faced by NASA engineers as they design the next generation of spacecraft, habitat, and communications technologies. This archived lesson plan lead students through design and testing, the evaluation process, documentation of results, and final shared reports.

AAAS Benchmark Alignments (2008 Version)
1. The Nature of Science
1B. Scientific Inquiry
6-8: 1B/M1b. Scientific investigations usually involve the collection of relevant data, the use of logical reasoning, and the application of imagination in devising hypotheses and explanations to make sense of the collected data.
6-8: 1B/M2ab. If more than one variable changes at the same time in an experiment, the outcome of the experiment may not be clearly attributable to any one variable. It may not always be possible to prevent outside variables from influencing an investigation (or even to identify all of the variables).
3. The Nature of Technology
3B. Design and Systems
6-8: 3B/M4a. Systems fail because they have faulty or poorly matched parts, are used in ways that exceed what was intended by the design, or were poorly designed to begin with.
6-8: 3B/M4b. The most common ways to prevent failure are pretesting of parts and procedures, overdesign, and redundancy.
4. The Physical Setting
4E. Energy Transformations
6-8: 4E/M2. Energy can be transferred from one system to another (or from a system to its environment) in different ways: 1) thermally, when a warmer object is in contact with a cooler one; 2) mechanically, when two objects push or pull on each other over a distance; 3) electrically, when an electrical source such as a battery or generator is connected in a complete circuit to an electrical device; or 4) by electromagnetic waves.
6-8: 4F/M3a. An unbalanced force acting on an object changes its speed or direction of motion, or both.
8. The Designed World
8B. Materials and Manufacturing
6-8: 8B/M2. Manufacturing usually involves a series of steps, such as designing a product, obtaining and preparing raw materials, processing the materials mechanically or chemically, and assembling the product. All steps may occur at a single location or may occur at different locations.
9. The Mathematical World
9B. Symbolic Relationships
6-8: 9B/M3. Graphs can show a variety of possible relationships between two variables. As one variable increases uniformly, the other may do one of the following: increase or decrease steadily, increase or decrease faster and faster, get closer and closer to some limiting value, reach some intermediate maximum or minimum, alternately increase and decrease, increase or decrease in steps, or do something different from any of these.
11. Common Themes
6-8: 11A/M2. Thinking about things as systems means looking for how every part relates to others. The output from one part of a system (which can include material, energy, or information) can become the input to other parts. Such feedback can serve to control what goes on in the system as a whole.
9-12: 11A/H2. Understanding how things work and designing solutions to problems of almost any kind can be facilitated by systems analysis. In defining a system, it is important to specify its boundaries and subsystems, indicate its relation to other systems, and identify what its input and output are expected to be.
9-12: 11A/H4. Even in some very simple systems, it may not always be possible to predict accurately the result of changing some part or connection.
9-12: 11B/H5. The behavior of a physical model cannot ever be expected to represent the full-scale phenomenon with complete accuracy, not even in the limited set of characteristics being studied. The inappropriateness of a model may be related to differences between the model and what is being modeled.
12. Habits of Mind
12C. Manipulation and Observation
6-8: 12C/M3. Make accurate measurements of length, volume, weight, elapsed time, rates, and temperature by using appropriate devices.
6-8: 12C/M5. Analyze simple mechanical devices and describe what the various parts are for; estimate what the effect of making a change in one part of a device would have on the device as a whole.
12D. Communication Skills
6-8: 12D/M6. Present a brief scientific explanation orally or in writing that includes a claim and the evidence and reasoning that supports the claim.
6-8: 12D/M9. Prepare a visual presentation to aid in explaining procedures or ideas.
