One of the exciting challenges for engineers is the idea of exploration. This lesson looks more closely at Spaceman Rohan, Spacewoman Tess, their daughter Maya, and their challenges with getting to space, setting up satellites, and exploring uncharted waters via a canoe. This lesson reinforces rockets as a vehicle that helps us explore outside the Earth’s atmosphere (that is, to move without air) by using the principles of Newton’s third law of motion. Also, the ideas of thrust, control and weight — all principles that engineers deal with when building a rocket — are introduced.

Designing and building a rocket requires many different types of engineers working together to create equipment that works properly. Engineers have to understand Newton’s three laws of motion as well as how exhaust behaves in order to calculate the thrust for a rocket to reach its destination. Engineers must also watch the weight of the rocket very carefully because a heavier rocket takes a lot more energy to get into space. Another important consideration for engineers is how the rocket will be controlled. Lastly, understanding how the rocket will behave in the Earth’s atmosphere — as well as in space — is critical in rocket design. To enhance stability, engineers can make use of various measures such as adding fins or small thrusters. Compare and contrast airplanes and rockets and explain why airplanes cannot travel into space.Define what thrust is and how rockets use thrust to get into space.Explain several considerations engineers have in designing rockets.Give an example of an explorer and describe reasons why explorers and exploration teams include engineers. 15TeachEngineering.orgJeff WhiteBrian ArgrowLuke SimmonsJay ShahMalinda Schaefer ZarskeJanet Yowellhttp://www.achievement.org/autodoc/page/ear0bio-1http://www.atk.com/rocketmotors/rocketmotors_rsrm.asphttp://www.allaboutspace.com/explorers/page/t/tereshkova.shtmlhttp://www.mounteverest.net/http://www.niehs.nih.gov/kids/quizwomentx.htmhttp://www.steponline.com/everest/junko_tabei.aspS11417B7International_Technology_Education_Association-ITEA_STL_StandardsTechnologyD.
