Target Audience, Project Description, Driving Question, Project Goals, Project Objectives, Rationale, Background, Standards, Assessments High school Physics, Geology and Pre-Calculus students; can easily be adapted for Integrated Physics and Chemistry students as well. This project is an exciting and collaborative project, which is used to tie together Physics, Pre-calculus, and Geology concepts. It allows the students to experience the life of a NASA engineer as they design and implement a Mars Rover Fueled on three different types of energy that can pick up a rock for analysis. Using these concepts they will design a mars land rover, present their proposals, and build and test their final and approved design. They will also be expected to present proposals and give oral presentations about their robotic mission. While working on their design they will become proficient in basic engineering and business software such as AutoCAD and Microsoft Power Point. Through emails, telephone calls to an assigned engineer mentor and a "Digital Learning Network" teleconferencing program hosted by JSC, students will learn what it means to be a NASA engineer. At the end of the project, students will demonstrate their Mars Rovers at a banquet opened to the community. Physics During the course of the project, students will explore these concepts using hands on methods through physical manipulative and interactive software. Through inquiry-based laboratory experiments, students will explore the concepts of force, work, and energy. Students will also have the opportunity to design their own labs when it comes to discovering different types of energy. Furthermore, students will be encouraged to share their discoveries with the rest of the class through various oral presentations. Pre-calculus Students will also be working with the mathematical concepts behind the main physical concepts. They will use interactive online simulations to see the abstract concepts of matrices and vectors. The students will work with the simulations to make observations about addition, subtraction, and multiplication of vectors when they create vectors in the plane to determine the relationships of vectors in 2 dimensions. They will also be able use the simulation to see how the dot product works and will be able to explain the dot product and to show work (w) equals force (f) times distance (d) is a dot product. Also, they will be able to show why the dot product is useful. Lastly, they will learn about the cross product and be able to relate it to the physics concepts needed for their project. GeologyStudents in the geology class will experience a wide variety of activities. Students will examine minerals and rocks first-hand and will also perform a balloon activity designed to represent the expanding universe and to help students understand Hubble’s Lab and Hubble’s constant. They will also learn how to identify surface features such as volcanoes, craters, and a river channels on a topographic map of Earth and relate what they’ve learned to a Mars map. Through geological principles such as Superposition, Horizontal Bedding, and Cross-Cutting Relationships, students will be able to tell a geological story of a given area on Earth and on Mars and then incorporate what they’ve learned when picking a Mars landing site. How would you design a robotic mission to Mars? In responding to the president’s challenge, NASA shifted its core mission to include, “inspiring the next generation of explorers…as only NASA can.” In doing so, they have worked to provide educators with a wealth of educational resources extrapolated from their unique missions such as the successful Mars Rover missions, Spirit and Opportunity. However, despite the plethora of rich resources, there is a lack of strong curriculum designed to effectively utilize the resources while cohesively connecting basic high-school concepts. Hence, the overall mission for the Mars-Bound project is to develop a strong, interdisciplinary curriculum that masterfully utilizes NASA-provided resources aimed at increasing student interest in science in math. Research has shown that students who are proficient in science, technology, engineering, and mathematics are more likely to pursue related subjects in high school and college and in career fields. Thus, the highest priority of our project is to create an environment where students are able to achieve the needed skills in an exciting and engaging manner. Students will be able to:

In an attempt to meet this challenge, we have developed an exciting interdisciplinary project that brings together Physics, Pre-calculus and Geology concepts. Over the course of 5 weeks, students will design a Mars robotic mission. As a result, students will develop a deep level of understanding of concepts not easily attainable through traditional instruction. During the course of the project, students will explore concepts using hands-on methods through physical manipulatives and interactive software. Moreover, each team will interact with engineers from Johnson Space Center through emails, telephone calls and a “Digital Learning Network” teleconferencing program hosted by JSC. One of the main goals of this project is to help students understand how math and sciences are intertwined, and how these subjects relate to real-world problems. By combining the curriculum in the students’ three courses to focus on the exciting Mars-based project, we also hope to engage and encourage our students to continue their pursuit of knowledge in these areas. However, in order for the interdisciplinary project to be successful, the educators involved need be familiar with the adequate background information. In this section, we aim to prepare the educators with the overall background information, as well as with the Physics, Pre-calculus, and Geology background information. One of the key aspects of this project is the interaction between the local NASA community and the students. Since this project was designed with the intent of using it in the Texas areas, many of the resources listed below relates to Johnson Space Center. However, if educators in other states are interested using this curriculum, they should look at their local NASA center’s website for contact information. First, before beginning your students in the project, it is important to contact JSC about assigning mentors for each group of students. To do this, you will need to contact Ms. Debbie Herrin (email: mailto:eduoutre@ems.jsc.nasa.gov ail) about JSC’s “Education Outreach Program”. The program seeks to capture young people’s interest in science, engineering, mathematics and technology. Over 200 JSC employees volunteer to share their knowledge and experience with teachers and students. Volunteers participate in various outreach opportunities including lecturing or performing hands-on activities in the classroom, career shadowing, tutoring, mentoring and judging at science fairs. It is recommended that you contact her at least three months prior to beginning the project. For more information abut the program, visit their website - http://education.jsc.nasa.gov/app/request.cfm. Also, the educators will also need to contact JSC about their “Distance Learning Network” program. Again, this should be done in advanced – at least 6 months. In doing this, you will be providing the students with a truly unique experience. The DLN is a live interactive video teleconference. Events are presented from unique JSC facilities (e.g., Neutral Buoyancy Lab and the Space Mockup Facilities). Students at all levels have the unique opportunity to interact directly with NASA representatives, experts, and even astronauts to gain new appreciation for the importance of science and education. To set up your event, you will need to visit the website - http://learningoutpost.jsc.nasa.gov/ . If you have any questions, you can also contact the project lead, Mr. Douglas Goforth (email: mailto:douglas.w.goforth@nasa.gov). Finally, since the project deals directly with a mission to Mars, it would be a good idea to be familiar with past and present NASA missions to Mars. It is recommended that educators spend some time reviewing NASA’s official Mars website - http://marsrovers.jpl.nasa.gov/classroom/. This website has information regarding past, present and future missions. Furthermore, it provides a plethora of learning resources ready to use in the classroom including lesson plans, multi-media resources, and links to other useful sites. Educators involved with the Physics component of the project should be familiar with the following:
This project’s main goal is to relate the concept of vectors to forces. In order to do this it is necessary to have the knowledge of adding, subtracting, and solving matrices. Also, it is important to know the concepts of vectors and be able to perform the dot product and cross product. To relate these concepts of vectors to forces it is important to know that force is a vector and the dot product is used to calculate work. This way it is easier to relate the real world concepts of forces when building the rover to the math that is necessary. When working with vectors the students are using geometry sketch pad, therefore it is helpful to know how the program works. Geology encompasses many topics, from rocks to paleontology to weather. The most fundamental elements are covered for this project. The general consensus for the formation of the Universe is the Big Bang (10-15 Billion years ago) based on background radiation and Hubble’s Law (galaxies are moving away from the Earth). Condensation of the Solar System began around 4.57 Billion years ago and this is also the time we find the earliest meteorites. The oldest known rocks on Earth are 4.1 Billion years old. We don’t find rocks older than this because they have been subjected to plate tectonics (subduction back into the mantle). A current theory for the formation of the moon is that a Mars-sized body collided with the proto-Earth around 4.5 Billion years ago which tilted the Earth’s axis to its current 23 degrees and the ejected material is what formed the moon. The moon is receding from the Earth at 3.7 cm/year which is slowing Earth’s rotation and causing our days to become longer each year. The moon’s rotation and revolution are the same so the same side of the moon is always facing Earth. Eventually, in 5 billion years, the Earth will constantly have the same side facing the Sun but at this point the Sun will have expanded and engulfed the Earth. The Earth formed through the process of differentiation. The spinning of the Earth acted as a centrifuge and as a result the heavier elements (sulfur, iron, and nickel) “sank” to the Earth’s center to form the core while the lighter elements (silicon, aluminum, and oxygen) “floated” to the top where they cooled and formed the outer crust. Between the crust and the core is the mantle (>90% iron, magnesium, silicon, and oxygen). Our present atmosphere and oceans were formed by evolution of primitive atmospheres and oceans that formed as a result of steam and gases released during volcanic activity. Around 2500 Million years ago there was an increase in oxygen and the process of life began. Fossil bacteria have been found that are as old as 3.5 Billion years old. Hypotheses for the formation of life include hydrothermal vents and extraterrestrial sources (comets). There was an explosion of life (the Cambrian Explosion) at 543 Million years ago in which there was an increase in diversity and preservation of hard bodies. The largest mass extinction occurred during the , around 250 Million years ago during which 95% of all species on Earth were lost. The most famous extinction is the Cretaceous-Tertiary (K-T) at 65 Million years ago which wiped out the dinosaurs. Theories for these mass extinctions include asteroid impacts, glaciation (rapid climate change), and volcanic eruptions (similar to impacts). Helpful definitions:
