This helicopter is called Ingenuity and is designed to test whether or not flight is a good way to study distant bodies in space.  \nWe have sent spacecraft to other planets, but this is the first aircraft that actually flew on another world. In this activity, you will learn about this amazing feat of engineering as you build your own Mars helicopter model.  \nSTEPS  \nSuggested Grades: 3–8  \nTime: 30 minutes  \nMaterials:  \n• 1 large marshmallow  \n• 4 small marshmallows  \n• 5 toothpicks  \n• Cardstock (to print out the helicopter parts of this document)  \n• Scissors  \n1. The large marshmallow will represent Ingenuity’s fuselage. Ingenuity is fairly small, about 19 inches tall and weighing about 4 pounds, and the fuselage is about the size of a softball. The fuselage contains batteries, sensors, and cameras to power and control Ingenuity’s flight. It is insulated and has heaters to protect the equipment in the cold Martian environment where it can reach  \n-130°C at night.  \n2. Insert the four toothpicks into the marshmallow so they come out at angles as shown in Figure 1. The toothpicks represent the four hollow carbon-fiber legs on Ingenuity. Ingenuity’s legs are designed to be lightweight while still supporting the helicopter when on the Martian surface. To take up less space, Ingenuity’s legs were folded while it was being carried to Mars.  \nFigure 1. Insert the four toothpicks into the marshmallow to represent Ingenuity’s legs.  \nFLIGHT LOG ENDORSEMENT CODE:  \nMARHELO  \n3. Place a sall marshmallow at the end of each of the four toothpicks as shown in Figure 2. These make the ends of the legs rounded, just like on Ingenuity.  \nThe rounded ends of the legs help the helicopter sit firmly, even on mildly uneven ground.  \nFigure 2. Small marshmallows are added on to the ends of the four toothpicks.  \n4. Print out the final page of this document on cardstock or other stiff paper. As shown in Figure 3, you will need to cut out one set of parts (a solar panel and two rotor blades) for each helicopter you are making.  \nNOTE: The final page contains two sets incase you are making multiple models – you only need one set per model.  \nFigure 3. Cut out one set of parts foryour helicopter.  \n5. Make a small hole (see Figure 4) in the middle of each of the parts you cut out in the previous step. This can be done using a pushpin or other sharp object. This is to allow the toothpick to be pushed through the paper. Be careful poking the hole – you may need the assistance of an adult.  \nFigure 4. Poke a small hole in the center of each of the parts you cut out in the previous step.  \n6. Push a toothpick through the hole in the center of one of the rotor blades. The rotor blade should be about 3/4 of an inch from the end of the toothpick as shown in Figure 5.  \nOn Ingenuity, each rotor blade is about 4 feet long and rotates very fast (about 2800 revolutions per minute) . The rotor blades need tobe this large and rotate so quickly in order to create enough lift, the upward force on the helicopter, in the extremely thin Martian air.  \nFigure 5. Push the toothpick through the hole in the center of one of the rotor blades.  \n7. Push the toothpick through the hole in the second rotor blade and adjust the blades so that they are aligned in different directions as shown in Figure 6. There should be a space of about 1/8 inch between the two rotors.  \nIngenuity has two rotor blades in order to create enough lift. Additionally, the two rotor blades rotate, or spin, in opposite directions. Normally when a rotor blade spins, it creates  \na force on the fuselage. By rotating in opposite directions, the forces created by the two rotor blades cancel each other out.  \nFigure 6. Push the toothpick through the second rotor blade and adjust the blades so they are aligned in opposite directions.  \n8. Push the end of the toothpick with t","cbCaiusoBfkWx2wT","https://ap.wps.com/l/cbCaiusoBfkWx2wT","pdf",1408929,"English","# Activity Overview\n# Steps\n## Materials and Setup\n## Assemble the Fuselage and Legs\n## Add Rotor Blades and Solar Panel\n## Attach Antenna and Final Placement\n# Further Information","[{\"question\":\"What is the goal of the Mars helicopter activity?\",\"answer\":\"The activity introduces how Ingenuity flew on another world and guides you to build a Mars helicopter model to learn about the engineering behind it.\"},{\"question\":\"What materials are needed to build the model?\",\"answer\":\"You need marshmallows, toothpicks, printed cardstock parts (cut using scissors), and a method for making holes such as a pushpin or other sharp object.\"},{\"question\":\"Why do the two rotor blades spin in opposite directions?\",\"answer\":\"The rotors create forces on the fuselage, and rotating in opposite directions helps the forces cancel each other out while still producing enough lift.\"}]","Build Your Own Mars Helicopter - Activity Overview | PDF",1792132274,15]
