StandardsEssential Questions How can we design a simple experimental procedure with an identified control and appropriate variables? What tools and procedures are needed to test the design features of our prototype? What protocol was used to determine if the engineering design process was successfully applied? How can we use data to draw conclusions about the major components of the universe? Are we able to explain how the relative distance of objects from the earth affects how they appear? SPI 0607.Inq.1 Design a simple experimental procedure with an identified control and appropriate variables. SPI 0607.T/E.1 Identify the tools and procedures needed to test the design features of a prototype. SPI 0607.T/E.2 Evaluate a protocol to determine if the engineering design process was successfully applied. SPI Use data to draw conclusions about the major components of the universe. SPI Explain how the relative distance of objects from the earth affects how they appear. Standards & EQs

Aerospace engineers design technologies that can fly inside and outside of the Earth’s atmosphere. There are many variables to consider when engineering a vehicle for space flight, so aerospace engineers often specialize on one aspect, such as aerodynamics or flight mechanics. Aerospace engineers collaborate with other engineers, scientists, mathematicians, and professionals on other aspects of space technologies. An important tool aerospace engineers use is the process of modeling. Since aerospace engineers design technologies that will be used in locations, which could be very different from Earth, they often use models and simulations to test the technologies. In this challenge, your team will learn about rovers sent to explore different destinations in space, and the rockets that transport them there. Your team will focus on creating models of technologies, such as rockets and rovers, that travel to distant worlds. Your challenge is to choose a destination to explore and design and create a rocket and rover specifically for that destination. Your team will consider what tools will be transported on the rover, but you are cautioned to choose wisely. Each tool adds more weight to the rover, and therefore to the rocket. Depending on the distance to your destination, the rover or rocket may have to be redesigned. In the end, can your rocket and rover travel safely to the destination chosen by your space commander? Liftoff Challenge

Rocket & Rover Destinations (from Earth): The Moon (Luna) 3 ft. (238,900 miles) Mars 10 ft. (57.4 million miles) Titan (a moon of Saturn) 15 ft. (886 million miles) Pluto 30 ft. (4.67 billion miles)

Restate your problem State what you already know List any limitations or controls

Complete research on the four destinations. Complete “Action Research” on how to get your rocket to each destination. Use a protractor to experiment with different angles. Test how far the rocket will fly with 0, 10, & 20 weights attached. What is the best combination of angles and weights for each destination? Action Research: Test how changing different parts of the rockets affects how far it goes.

Why did engineers at NASA include different tools on the Curiosity Rover? What are the different uses of the tools on the Curiosity Rover? Mars: Curiosity Rover

Design and Create a Rover Your team will work together to make a rover to explore a certain destination in space. Each team will decide what tools will go on their rover. Remember, choose tools wisely so that the rover is not too heavy for a rocket to launch its weight. IMPORTANT! Please note your team’s mission for your destination and make sure the tools you choose will help you complete the mission. The rover starts with a minimum of four weights to account for the weight of the body and the battery.

1.Complete the rover checklist by choosing your rover tools. 2.Materials manager, pick up your team’s rover and tools scissors, and tape. 3.Color and assemble the rover by cutting out the tools your team chose and attach the tools to your rover with tape. 4.Pick up the number of washers that represent the weight of their rovers in order to feel the weight. Side note: the next lesson will require your team to engineer a rocket that can carry the weight and still reach your destination. 5.Name your rover. Rover Instructions
