Become a Part of Space History -- Grades K-4
Charting Your Journey to Mars!
Students will study the effects of radiation on human space travelers and analyze different materials that simulate space radiation shielding for Orion. After participating in activities guided by their teachers, students will recommend materials that best block harmful radiation.
All students completing the challenge can join participants from around the world to celebrate the Exploration Flight Test-1 of Orion by having their names flown on board as virtual crew members. The deadline to submit student names for the virtual crew is July 31, 2014.
Get started. Follow the steps on this page to guide K-4 students through activities to complete the challenge.
Step-by-Step Educator Guide -- Grades K-4
Step 1: Register to Participate in Exploration Design Challenge
Register before beginning the NASA Exploration Design Challenge. Registration is easy and free.
Click on the registration link. You will be taken to a National Institute of Aerospace website to complete the process. After registering, you will receive a confirmation email, which includes a link to submit student names for the virtual crew upon completion of the challenge. Please keep this email until completion of the challenge.

Step 2: Introduce the Design Challenge
A. Use the following Student Scenario to introduce students to the NASA Exploration Design Challenge for grades K-4.
When traveling in space, the space vehicle protects astronauts from space debris, which usually can be seen, and space radiation, which cannot be seen. One of the most difficult things to block is space radiation, and it is also the most deadly. Space radiation affects human cells and tissues.
For long space missions, materials used to build the spacecraft must give the space explorer more protection from space radiation than what is currently provided.
NASA and Lockheed Martin are developing the Orion Multi-Purpose Crew Vehicle. Orion will serve as the exploration vehicle that will carry the crew to space and protect them during extended space travel.
B. Encourage students to ask questions about Orion and the challenges explorers will face traveling to Mars by viewing one or more of NASA's "Ask the Experts" videos found on the NASA Exploration Design Challenge website.
Step 3: Guide Student Scientists
A. Complete Part 1 of the Ray Shielding Activity. Part 1: Steps 1-10 in the Instructional Procedure will help guide student scientists through an experimental analysis of different materials and their ability to block simulated space radiation.
B. Background information, procedures and a data collection chart for Part 1 is included in the Ray Shielding Student Section.
C. The Ray Shielding Activity can be modified easily for students in grades K-2. Younger students may not be able to complete the data collection charts, but they can test assorted materials such as tissue paper, construction paper or cardstock to see which materials best block the simulated radiation.
D. Use these additional/optional resources to help guide learners through the Ray Shielding Activity.

› Script [2MB PDF file]
› Presentation [4MB PDF file]
Step 4: Guide Student Engineers
A. Challenge student engineers to design a solution for the following problem.
Problem: Which of the materials provided will block the most simulated space radiation and be the best material for designing a radiation shield for Orion?
B. Use the Elementary School Design Packet for Grades K-5 to guide student engineers through the design process.

Step 5: Submit Student Names for the Virtual Flight Crew
A. Once students have completed Steps 2 - 4, please submit student names for the virtual crew by using the link on your confirmation email. If you need to have the link re-sent to you, please send an email to firstname.lastname@example.org.
These student names are added to a list of all participants in the NASA Exploration Design Challenge. The list of names will fly on the Exploration Flight Test-1 of Orion as virtual crew members. The virtual crew will be the only crew flying on Orion’s inaugural mission. The names must be submitted by July 31, 2014, to join the virtual crew.
B. After submitting these names, download certificates recognizing participation in the NASA Exploration Design Challenge. Certificates for both students and educators are available for download and may be duplicated.
Step 6: Encourage Student Experts
A. Extend student interest and engagement by returning to the NASA Exploration Design Challenge website to find new video segments, resource links, and press releases.
B. Additional activities in the Resources section may be completed to strengthen student understanding about radiation and the effects of radiation on humans. These activities include inquiry explorations, hands-on activities and interactive simulations.
Safety in the Educational Classroom and Laboratory
Safety is an important goal for all curricular areas of education. Safety issues are a special concern for STEM-based (science, technology, engineering and mathematics) activities and courses. Many national and state academic standards address the need for schools and subject areas to promote student development of knowledge and abilities in a safe learning environment.
It is the responsibility of the school's administration for providing a learning environment that is safe, up-to-date and supportive of learning. Additionally, teachers are responsible for their students' welfare in the classroom and laboratory.
Teachers must be knowledgeable and diligent in providing a safe learning environment. Students should receive safety instructions relevant to the topics being taught. Assessments must accompany the lessons on safety, and records must be kept on student results. The teacher must properly supervise students while they are working. The teacher must inspect and maintain equipment and tools to ensure they are in proper working condition. Parents should be informed about the subject in which their child is enrolled and should be educated about the safety plan that is being used. The teacher should develop a safety checklist to assure safe conditions exist and procedures are being followed in the classroom and laboratory.
Below are examples of safety rules that may be used. Teachers should develop their own safety rules to fit the needs of their classroom.
- 1. Conduct yourself in a responsible and safe manner at all times.
- 2. Follow all written and verbal instructions carefully. If you do not understand a procedure or how to use a tool, ask your teacher before proceeding.
- 3. Keep your work area clean at all times.
- 4. Use proper safety protection, i.e., gloves, goggles, proper clothing.
- 5. Notify your teacher in an emergency.
