INTRODUCING THEDESIGN PROCESSWhen NASA engineers try to solve a problem, their initial ideas rarelywork out perfectly. Like all engineers, they try different ideas, learnfrom mistakes, and try again. The series of steps engineers use toarrive at a solution is called the design process.As kids work through a challenge, use questions such as the onesbelow to talk about their work and tie what they’re doing to specificsteps of the design process.IDENTIFY PROBLEMBRAINSTORMBrainstormingDESIGN At this stage, all ideas are welcome, and criticism is not allowed. What are some different ways to start tackling today’s challenge?BUILDDesigning Talk through the brainstormed ideas. What’s really possible givenyour time, tools, and materials? What specific goal are you trying to achieve, and how will you knowif you’ve been successful?REDESIGN What are some problems you’ll need to solve as you build yourproject?TEST &EVALUATEBuilding, testing,evaluating, and redesigning Does your design meet the goal set out in the challenge?

Leading a Challengefor eVents and Grades 3–8LaunCH itLEADER NOTESNever led an engineering challenge before? Don’t worry! From getting started, tohelping kids succeed, to wrapping up the activity, the leader notes give you all youneed to facilitate a challenge with kids. The leader notes are divided into thefollowing sections:The ChallengeDesign and build an air-powered rocket that can hit a distant target.In this challenge, kids follow the engineering design process to: (1) design and build arocket from a straw; (2) launch their rocket using a balloon; (3) improve their rocket basedon testing results; and (4) try to consistently hit a target with their rockets.1Prepare ahead of time2Introduce the challenge (10 minutes) Read the challenge sheet and leader notesto become familiar with the activity. Gather the materials listed on the challenge sheet.Basic air-poweredrocket, straw andballoon connection,straw and strawconnection Build a sample rocket and launcher. Tell kids about the role rockets play in getting people and equipment to the moon:To get to the moon, NASA uses a rocket. A rocket is basically a huge engine that liftsthings into space. Sometimes rockets carry people (called astronauts) into space. Sometimes,they carry NASA’s space shuttle, a satellite, or other piece of space equipment. Today you’ll makea rocket out of straw that uses air power to hit a target. By testing your rocket, you’ll find ways tomake it work better. Improving a design based on testing is called the engineering design process. Show kids your sample rocket and launcher. See if they can name the main parts.The large column that makes up most of the rocket is called the body. The wing-like sheets stickingout from the lower end of the body are called fins. The small capsule that sits atop the body is thenosecone. The nosecone is where the astronauts sit or where NASA stows the satellites orequipment it sends into space.Prepare ahead of time: Lists things to do to get ready for the activity.3Brainstorm and design (10 minutes)Distribute the challenge sheet. Discuss the questions in the Brainstorm and Design section. What are some ways you can change a rocket? (Kids can change: the length of the straw; thestraw’s weight; the weight and shape of the nosecone; the number and position of fins; the amountof air in the balloon; and how they release the air.) How will adding weight to the straw’s nose or having fins affect how it flies? (Adding weight tothe straw’s nose or placing fins near the back can help it fly straighter.)Introduce the challenge: Provides a script you can use to introduce the activity’skey ideas and show how the challenge relates to NASA’s goal of having people liveon the moon.Brainstorm and design: Helps kids think about different ways to meet a challenge.Since challenges offer kids many ways of succeeding, this section jump startstheir thinking about various approaches and possibilities. When you launch your straw rocket, how does the launch angle affect where it lands?(Launching a rocket straight up sends it high but not far; straight out makes it fall quickly to the floor.This could be a great opportunity to explore angles with kids.)4 sticks to the launch straw—The straw might have become wet as kids blew through it. If so, havethem wipe it. Also, check that the balloon is inflated enough. veers off course—Add fins, either at the rear or middle of the rocket. lands on its side instead of nose first—Add a little weight to the nose.9Leader notes pagea nasa/desiGn sQuad CHaLLenGeLaunCH itGoing to the moon? You’ll need a rocket. Plus some things tokeep busy. The rockets NASA sends to the moon go up to 18,000miles (29,000 km) per hour. But it still takes about three days toget there. So, sit back, relax, and enjoy the view.Build, test, evaluate, and redesign: Lists issues that might surface during achallenge and suggests strategies to use with kids who face these issues.we CHaLLenGe You to design and build an air-powered rocket that can hit a distant target.BrainstorM and desiGnThink about things that might affect how your air-powered rocket flies. How long will your rocket be? How many paper fins will your straw rocket have—0, 2, or more? How will adding weight to the straw’s nose or having fins affect how itflies? When you launch your straw rocket, how does the launch angle affectwhere it lands?Discuss what happened: Provides questions (and answers) for reviewing theactivity’s key concepts, helping kids reflect on how they used the design process(see page 2 for an overview of this process), and highlighting how the challengerelates to NASA’s moon-exploration efforts.Curriculum Connections: Lists the topics in a challenge that relate to conceptscommonly covered in science, math, and technology curricula.BuiLdMateriaLs (per rocket) balloonsmall lump of claypaper1 wide straw1 thin straw that fits insidethe wide straw tape target (box lid or paperwith a bull’s-eye drawn on) scissors1.

For example, if the straw rocket: falls quickly to the ground—Reduce theweight. misses the target—Launch it at differentangles. won’t fly straight—See if fins make adifference. Also, try adding weight to therocket’s nose. sticks to the launch straw—Makesure the launch straw is dry. If it isn’t,wipe it dry. Also, try blowing theballoon up more.launcher(thin straw)balloonKids’ challenge sheetTips for facilitating open-ended challengesDesign Squad TM/ 2008 WGBH Educational Foundation There are multiple ways to successfully tackle achallenge, so one successful solution is as goodas another. Help kids see that the challengesare not competitions. Instead, they’reopportunities to unleash an individual’s ingenuityand creativity. Have kids come up with several ways to solve aproblem before they move ahead with an idea.Photo: Renée Mattier When kids feel stuck, have them describe whatthey’re doing by explaining why they think theygot the results they did. Then ask questions toget kids back on track rather than telling themwhat to do. For example, ask: “Why do you thinkthis is happening?” or “What would happenif ?” or “What is another thing you could try?” When something’s not going as desired,encourage kids to try again. Problems areopportunities for learning and creative thinking.If a design doesn’t work as planned, encourage kids totry again. Setbacks often lead to design improvementsand success.4
Going to the moonwith nasaCould people live on the moon for months at a time? Yes! By the year 2020, NASAplans to build a lunar outpost capable of housing teams of astronauts for sixmonths or more. But there’s a lot to learn before this can happen. Between nowand then, NASA will prepare by sending several robotic missions to: identify good landing sites. Orbiting spacecraft will image and map the surfaceand identify hazards, such as steep slopes, rough terrain, and other obstacles. measure temperature, lighting, dust, and radiation levels. NASA needs to knowthis to design materials and equipment that will work reliably on the moon andassure astronaut safety. look for useful resources, such as minerals and ice. Shipping things from Earthis costly—over 25,000 a pound! NASA needs astronauts to make as much aspossible of what they need on site, using raw materials found on the moon,like calcium compounds to make cement and nitrogen compounds to fertilizecrops.Imagination fuelsinnovationTo explore the frontiersof Earth, the solar system,and the universe, NASAengineers find solutionsto extraordinarychallenges, and turndreams into reality.Design Squad TM/ 2008 WGBH Educational FoundationThe two missions featured in this guide—the Lunar Reconnaissance Orbiter andLunar Crater Observation and Sensing Satellite—are the first two missions NASAis sending and are the first step in NASA’s effort to return to the moon.NASA plans to build a lunar outpost to house astronauts for six months or more.Get this image at: www.nasa.gov/images/content/148658main jfa18833.jpg5
