  • I will be able to understand Goldilocks Principle in relation to the importance of the Earth’s atmosphere and how it sustains life

  • I will be able to answer the following questions:

    • Compare and contrast Earth’s atmosphere to that of Venus and Mars. You may draw pictures to describe the difference, create a Venn diagram, draw a chart, or just write a description.

    • Explain how Earth’s atmosphere functions to keep us alive.

    • Predict what would happen to an astronaut if he were to take off his mask on the three different planets(Earth, Venus, and Mars)


What is an atmosphere

  • The mixture of gases surrounding the Earth or other celestial body, held in place by gravity

    • What does it mean by mixture?

      • Different types of gases blended together. For example, oxygen, nitrogen, carbon dioxide, water vapor, etc.

      • Mixture can be separated.

      • For example, trail mix is a mixture. You can separate the raisins from the almonds and M&M’s

      • How do you separate a mixture of air? It’s gases mixed together. Through a process called fractional distillation, the gases are cooled and compressed and expanded to liquefy them. Elements and compounds have different temperatures that they liquefy.

  • Place the correct pie chart with the correct planet.

    • Hint: Think about what gas should be present or absent to make a planet too hot, too cold, and just right


Venus too hot

  • 2nd planet from the sun

  • Similar atmosphere composition to Mars

    • 96.5% CO2

    • 3.5% N2

    • trace O2

  • Very dense atmosphere

  • CO2 concentration causes hot temperature and very hot greenhouse effect

  • Too hot to sustain life

  • Very high pressure

  • Trapping of the sun’s radiation by the combination of gases found in the atmosphere, which causes a planet to warm

  • CO2 concentration usually behind the trapping of infrared radiation

    • Other gases include water vapor, methane, and CFC’s


Mars too cold

  • 4th planet from the sun

  • Very thin atmosphere

    • 95% CO2

    • 2.7% N2

    • 0.13% O2

  • Due to thin atmosphere CO2 concentration has no effect on warming the planet, very low surface temperature

  • Too cold to sustain life

  • Very low pressure

    • Just the right amount of greenhouse gases (CO2, water vapor, methane) to warm the planet to sustain life

  • Composition of atmosphere

    • 78% N2

    • 21% O2

    • 0.9% Ar

    • Trace amount of greenhouse gases

  • Life on Earth helps sustain our atmosphere through the cycling of oxygen via photosynthesis

  • Without life Earth would either be like Mars or Venus

  • Pressure in between Mars and Venus

    First , you are going to complete a Training Module

    You are going to be changing the amount of gases

    You are going to write detailed observation s about what happened

    ex. When the _____ was lowered first, the fish died. Then the grass and trees died. And finally all the animals died. The temperature dropped. Lowering ____made life on Earth cease and lowered the temperature.

    Your second module is a Challenger module. You may need to refer to your notes for assistance for completion.
