Misión: Sobrevivir en Marte

Los colonizadores han llegado a Marte y tienen que solventar varios desafíos. El primero es poder respirar y otro no más importante, obtener alguna fuente de energía para producir la electricidad necesaria en sus equipos.

A partir del agua encontrada en las rocas y del suelo marciano, se podrían obtener tanto oxígeno que les permitiría respirar como el hidrógeno que serviría de fuente de energía y su transformación posterior en electricidad.

Los equipos de tres o cuatro viajeros deberán resolver pequeños problemas científicos. Tras cada test resuelto correctamente se oculta una pista, que les llevará a descubrir el procedimiento que les permita obtener los dos preciosos elementos químicos que necesitan para su supervivencia.

Nuestros colonizadores deben dominar no solo su lengua materna sino también el inglés, ya que en los viajes interplanetarios las comunicaciones se realizan en este idioma internacional.

THE MISSION - GETTING OXYGEN FROM WATER.

• Your group is walking towards the base, but your oxygen reserves are running out. So you will not arrive…

• In the distance, on your way to the base, you see a metallic structure; it is the rover “Opportunity”. One of you thinks you are saved; has a great idea.

• This old rover collected rocks filled with water and keeps them in airtight tubes. If you get the water; getting oxygen from it is very easy.

This is your mission:

• Taking advantage of the materials that you will find in the "Opportunity". You must first obtain the water and from it the oxygen necessary to survive.

• You will build the facility to obtain the oxygen.

• You will record a video obtaining the precious gas; you will be saved and the test will be a success. It will be sent through “Classroom” to the teacher.

Rewards and penalties

• I will present you small tests of physico-chemical calculations. If you solve 3 of them correctly, I will give you a clue or part of the material necessary to produce oxygen.

• The tests will only be valid if the mathematical or physical-chemical processes studied in class are used. Other types of results will not be considered valid.

• With the final materials obtained, you should think about what type of process you should use to obtain oxygen.

• The only possible language in our communications is English. Spanish is forbidden

Test and clues

0.- First of all, you have to find information about how to get oxigen from water. Use your Pc but only one for group. Make a list of the materials you need.

Clues to solve:

1.- Perseverance has the following measurements: length 3m x width 2.7 m and height 2.2 m. Could you calculate its volume in inches?

2.- Another spacecraft will collect the rock samples that Perseverance will collect from the Martian soil in 2031. How long, in seconds, will it take until then?

3.- The launch of the probe that carried Perseverance to Mars left on July 30, 2020 and landed on February 18, 2021. How many days, hours and seconds did the trip last?

4.- On Earth at 20ºC and an atmosphere we have 25 liters of oxygen. If we can maintain the same pressure; What volume will that oxygen occupy, knowing that the Martian temperature is -50ºC? What earthly law have you used to solve it?

5.-Jezero is an impact crater on Mars, where Perseverance landed and once housed a lake. The diametre is 47,5 km. could you calculate the surface of the lake?. Express the results in I.S.

6.- The average temperature at night on Mars it reaches -80ºC. And the pressure is only 600 Pascals. Change this pressure to atmospheres and then calculate, what temperature would be reached at the pressure of the earth?. What earthly law have you used to solve it?

7.- The first pile in the story “Volta pile” was made up of the element Z=30 and the element Z=29. Could you tell me what those elements are, the electron configuration of Z=29 and a binary salt of the other element.

8.- To obtain in the metallurgical industry, the metal you need in your installation, two reactions take place. Could you write them? (this information is given in spanish)

1.- Monosufuro de dicobre + oxígeno molecular → oxido de cobre (I) + dióxido de azufre

2.- Monóxido de dicobre + sulfuro de cobre (I) → Cobre + oxido de azufre (IV)

1.-

2.-

9.- Calculate the molecular masses of each different chemical compounds that appeared in test 4.

10.- What process do you need to apply to obtain the water from the rock?. what process do you need to obtain the oxygen from the water?

1.- Process:

2.- Process:
