Teacher guide & answers
In this lesson: Distinguish observations, a research method and an unresolved scientific aim.
Euclid Opens Its First Major Data Collection
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 does DR1-Foundation bring together?
Correct answer: C — Approximately 13 months of observations
Why: The first paragraph defines the contents of the release.
Clue in the story: Euclid’s DR1-Foundation release brings together approximately 13 months of observations, ESA announced on November 12. It records light from over a billion objects.
Why would claiming the mysteries are solved be unsupported?
Correct answer: B — The text describes investigation as an aim
Why: The second paragraph says mapping is intended to help investigate the mysteries, rather than establish they are solved.
Clue in the story: Researchers can now begin constructing a detailed three-dimensional cosmic map. Such mapping is intended to help investigate dark matter and dark energy, rather than establish that those mysteries have already been solved.
The open question: accept different answers
Ask learners: Describe the available evidence and one conclusion the text does not support.
One possible answer: The release records light from over a billion objects across approximately 13 months. It supports construction of a map for investigating dark matter and dark energy, but does not show that those mysteries have been solved.
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.
Grammar to discuss
An intended purpose
is intended to help investigate
Is intended to states a purpose; successful resolution of the research questions is not asserted.
