■ CER: Nuclear Fusion & Spectroscopy Prompt: Make a claim explaining how nuclear fusion in stars creates new elements and how we use spectroscopy to tell us what elements are in stars. ✍■ Sentence Starters Claim • Nuclear fusion in stars… • Fusion changes elements by… • Spectroscopy shows… Evidence • One piece of evidence from our [notes/lab/reading] is… • The spectrum of a star shows lines for… • Our class reading explained that… • From our spectroscopy lab, we saw that… Reasoning • This evidence supports my claim because… • When we see hydrogen and helium lines, it means… • The presence of new element lines tells us… • This shows nuclear fusion is happening because… ■ Evidence Hints (from classwork only) • • • • • Notes: Nuclear fusion in stars combines hydrogen atoms into helium and can form heavier elements. Notes/Reading: Spectroscopy shows absorption or emission lines that match specific elements. Lab: Different elements give unique spectral “fingerprints.” Reading: Stars have hydrogen and helium lines, showing both the fuel (H) and product (He) of fusion. Notes: Heavier elements found in spectra (like carbon or oxygen) show that stars create new elements through fusion. ■ Remember: Use scientific sentences — do not start with “I think” or “I believe.” State your claim and back it up with evidence and reasoning.
