In this lesson: Identify why arcs appear and compare telescope views.
Gravity Makes Distant Galaxies Look Bent
How to use these two pages
Give learners the student worksheet. It contains the story and questions, without the answers. Keep this guide for yourself. Use it to lead the activity and explain the answers afterwards.
Student worksheetA simple 15–20-minute lesson
- Before reading · 2 minutes
Show the title. Ask: “What do you think this story is about?”
- Read and answer · 8–10 minutes
Give out the student worksheet. Learners read for the main idea, then reread to answer the 2 questions. They can compare answers with a partner.
- Discuss and write · 5–8 minutes
Check the answers below together. Ask learners to point to the clue in the story, then finish with the open question.
Adjust the support: Let learners use word help or Level 1 if needed. For a challenge, compare the wording in another level. This activity is not a proficiency test.
Answers to the 2 questions
The question numbers match the student worksheet. Each answer includes a reason and the clue learners can find in the story.
What bends the light?
Correct answer: B — Gravity
Why: The first paragraph attributes the bending to gravity.
Clue in the story: NASA shared Hubble images of gravitational lenses on November 12. Gravity bends light from distant galaxies, making arcs in the images.
Which telescope covers a wider area?
Correct answer: A — Roman
Why: The second paragraph contrasts Roman’s wider area with Hubble’s detail.
Clue in the story: Hubble shows individual lenses in detail. The Roman telescope can cover a wider area to find more of them.
The open question: accept different answers
Ask learners: Explain the arcs and the different views of the two telescopes.
One possible answer: Gravity bends light from distant galaxies and makes arcs. Hubble shows individual lenses in detail, while Roman covers a wider area.
This is an example, not the only correct answer. Look for a relevant idea, a reason and the learner’s own words. Learners can answer aloud or write one or two sentences.

Purpose
to find more of them
To introduces the purpose of covering a wider area: finding more gravitational lenses.
