🌌 Part 1: Understanding the Big Bang Theory

1. According to the Big Bang theory, when did the universe begin? Explain your answer.

Sentence starters:
• The universe began approximately...
• Según la teoría del Big Bang, el universo comenzó aproximadamente...

2. Analyze the relationship between the expansion of the universe and temperature changes since the Big Bang. Use evidence to explain how these two factors are connected and what this tells us about the early universe.

Sentence starters:
• The expansion of the universe is connected to temperature because...
• La expansión del universo está conectada con la temperatura porque...

3. Compare and contrast three pieces of evidence that support the Big Bang theory. Rank them from strongest to weakest evidence and justify your reasoning:

Sentence starters:
• The strongest evidence is... because it demonstrates...
• La evidencia más fuerte es... porque demuestra...
• In comparison, ... is weaker evidence because...
• En comparación, ... es evidencia más débil porque...

4. Complete this statement and explain: The Big Bang theory states that the universe began as an extremely ________ and ________ point that rapidly expanded.

Sentence starters:
• The universe began as an extremely... because...
• El universo comenzó como un punto extremadamente... porque...

📝 Part 2: Analyzing the Evidence

5. Evaluate the Big Bang theory by examining both its strengths and limitations. What questions does this theory answer well, and what aspects of the universe does it struggle to explain?

Sentence starters:
• The Big Bang theory successfully explains... but it has limitations in...
• La teoría del Big Bang explica exitosamente... pero tiene limitaciones en...

6. Construct an argument for why the Cosmic Microwave Background radiation is considered the most compelling evidence for the Big Bang theory. Include at least two reasons and explain how this evidence connects to the theory's predictions:

Sentence starters:
• The CMB is the most compelling evidence because first..., second...
• La radiación de fondo cósmico es la evidencia más convincente porque primero..., segundo...

7. Think-Pair-Share: Analyze how Hubble's observations of galaxy redshift support the Big Bang theory. Explain the logical chain of reasoning that connects these observations to the conclusion that the universe is expanding:

Sentence starters:
• Hubble observed that galaxies show redshift, which means... This supports the Big Bang because...
• Hubble observó que las galaxias muestran corrimiento al rojo, lo que significa... Esto apoya el Big Bang porque...

8. Partner's idea from discussion:

Sentence starters:
• My partner shared that... / Mi compañero compartió que...

9. Synthesize your understanding: If you had to convince a skeptical friend that the Big Bang theory is valid, what combination of evidence would you present and how would you address potential counterarguments?

Sentence starters:
• To convince a skeptic, I would present... because this evidence shows...
• Para convencer a un escéptico, presentaría... porque esta evidencia muestra...

10. Predict what might happen to our understanding of the Big Bang theory as new technologies allow us to observe deeper into space and further back in time. Support your prediction with reasoning:

Sentence starters:
• As technology advances, I predict our understanding will... because...
• Mientras la tecnología avanza, predigo que nuestro entendimiento... porque...
