In this activity, the student will work as astrochemists to try to analyze the composition of the atmospheres of Mars and Earth. To do this, they are going to create a construction game of molecules that are more representative of the atmosphere of Mars.

Later they will be able to perform the same exercise for the molecules of the atmosphere of the Earth and the other planets of the Solar System, reaching conclusions of the existence of life, as we know it.

RECOMMENDED AGES : 14–18 years

KEY COMPETENCES (LOMLOE):

• Mathematical and science, technology and engineering competence
• Personal, social and learning to learn competence
• · Citizenship competence
• Competence in cultural awareness and expression

DIDACTIC OBJECTIVES:

• Learn about the gases in the atmosphere of Mars and Earth.
• Compare both compositions (atoms and molecules as well as their proportions).
• Build the molecules with a set of balls (atoms) and sticks (bonds).
• Differential between double and single covalent bonds.

MATERIALS:

• Set of balls (representing different molecules) and different sticks (representing different bonds)

INCLUSION:

• Adaptable for students with low hearing and ASD (guidelines outlined in the guide are followed)
• Adaptable for students with low vision or knowledge (contrast between colors and shapes to be built)
