Question

slide 3: the miller-urey experiment
big idea: scientists tested if life’s building blocks could form naturally.
include:

• a picture or diagram of the experiment
• labels: water, gasses, sparks
• 1-2 sentences explaining:
• what the experiment tested
• what was created (amino acids)

Explanation:

To complete the task about the Miller - Urey experiment:

Diagram (Simplified)

Component	Description
Mix of Gases (CH₄, NH₃, H₂)	Represents the primitive Earth's atmosphere.
Spark Generator (Electrodes)	Represents lightning, which provides energy.
Condenser	Cools the vapor, turning it back into liquid.
Collection Flask	Where the liquid (with newly formed compounds) is collected.

(1 - 2 sentences)
The Miller - Urey experiment tested whether the building blocks of life (like amino acids) could form naturally under conditions similar to the primitive Earth. By simulating the primitive atmosphere (with gases), ocean (with water), and lightning (with sparks), the experiment successfully created amino acids, which are key components of proteins and essential for life.

Labels Explanation

• Water: The boiling water in the first flask represents the ancient oceans, and the water cycle (evaporation - condensation) is part of the experimental setup to circulate the gases and any formed compounds.
• Gasses (CH₄, NH₃, H₂): These gases are used to mimic the composition of the Earth's early atmosphere, which is thought to be different from today's (with little to no oxygen).
• Sparks: The sparks from the electrodes simulate the lightning that was common on the primitive Earth and provide the energy needed to drive chemical reactions between the gases and water.
