Vocabulary Learning
🌌 The 'Opposite' Pair
Look at how the text describes stars. It uses a simple pattern to show differences:
- Blue Hot
- Red Cool
⚡ Fast vs. Slow
The text says the galaxy makes stars "very fast."
To describe things in your life, use:
[Subject] + [Verb] + [Adverb]
- The galaxy (Subject) + makes (Verb) + very fast (Adverb).
- I (Subject) + walk (Verb) + slowly (Adverb).
📏 Comparing Sizes
When we talk about two things, we add -er to the word:
Small Smaller
Example from text: "It is much smaller than our galaxy."
Rule: Use "Smaller than..." when comparing a tiny thing to a big thing.
