Climate Change Snapshot

Overview

Students explore climate change by using evidence-based reading and writing to explain causes, effects, and how humans contribute to observed trends. The lesson builds skill in using domain-specific terms, organizing ideas for a short scientific explanation, and citing information from provided sources.

Learning intentions

• Students will be able to explain key concepts of climate change, including causes and effects, using accurate scientific language.
• Students will be able to determine the meaning of climate-related symbols and domain-specific terms in context.
• Students will be able to introduce a claim and organize reasons and evidence logically in a short scientific paragraph.
• Students will be able to gather and summarize information from multiple provided sources without copying.

Success criteria

• I can distinguish weather from climate and describe at least two causes of climate change.
• I can identify and explain at least two effects of climate change (for people or ecosystems).
• I can write a short claim-based explanation with organized reasons and evidence from the sources.
• I can correctly use key climate terms (for example: greenhouse gases, temperature trend, sea level, feedback).

Curriculum links

• Reading in Science and Technical Subjects: Determine the meaning of symbols and domain-specific words in context (CCSS.ELA-LITERACY.RST.6-8.4).
• Writing in History/Social Studies, Science, and Technical Subjects: Introduce topic clearly, organize ideas, and include formatting/graphics when useful (CCSS.ELA-LITERACY.WHST.6-8.2a).
• Writing: Introduce claim(s), distinguish from alternate claims, and organize reasons and evidence logically (CCSS.ELA-LITERACY.WHST.6-8.1a).
• Writing: Gather relevant information from multiple print and digital sources, assess credibility/accuracy, and quote or paraphrase while avoiding plagiarism using standard citation format (CCSS.ELA-LITERACY.WHST.6-8.8).

Lesson structure (45 minutes)

1. 0–5 min · Hook (Think–Pair–Share). Teacher displays three statements on the board: “Weather can change daily,” “Climate changes over long time periods,” and “Human activity affects climate.” Students think individually, then pair to decide which statements are true and why.
2. 5–12 min · Mini-lesson: domain terms + symbols. Teacher models reading a short “data snapshot” handout showing a simple line chart (example: rising global temperature trend) and a glossary box. Students highlight one term and one symbol/graphic feature, then write a quick “meaning in context” sentence for each.
3. 12–22 min · Source reading (multiple texts). Teacher distributes two short, student-friendly sources: Source A (brief explanation of greenhouse gases and causes) and Source B (brief explanation of impacts such as sea level rise, heat extremes, or ecosystem changes). Students read silently, then complete a two-column organizer: “Cause/evidence” and “Effect/evidence.”
4. 22–30 min · Discussion: claim vs. alternate explanation. Teacher prompts: “What evidence supports the claim that climate is changing over time? What alternate ideas might people have, and how could we address them with evidence?” Students discuss in small groups and record one supporting reason and one possible opposing idea (without arguing personally).
5. 30–40 min · Writing: structured paragraph. Teacher shows a paragraph frame with headings: Claim, Reason 1 + Evidence, Reason 2 + Evidence, Address an alternate idea. Students draft a short explanation using at least two pieces of evidence from Sources A and B, using a simple citation format provided on the handout (for example: “Source A” / “Source B”).
6. 40–45 min · Exit ticket (quick assess). Students complete an exit ticket with two parts: (1) “Define one key term from today and explain its meaning in this context,” and (2) “Write one sentence naming an effect of climate change and one type of evidence you used.”

Resources

• Two short climate change sources (Source A and Source B), grade-appropriate reading level
• “Data snapshot” handout with a simple temperature trend line chart and one or two symbols/labels
• Domain term list (greenhouse gases, temperature trend, sea level rise, heat extremes, feedback, climate vs. weather)
• Cause/effect evidence organizer (one per student)
• Paragraph frame with headings and a citation reminder (Source A/Source B labels)
• Highlighters or sticky notes
• Exit ticket slips or digital equivalent
• Projector/board for hook statements and discussion questions

Assessment

• Formative during reading: teacher checks organizers for accurate cause/effect pairing and correct term meanings in context.
• Formative during discussion: listen for whether students reference evidence from the provided sources (not opinions alone).
• Exit ticket: evaluate term accuracy and ability to connect an effect to evidence used in the paragraph.

Differentiation

• Provide sentence starters for the organizer and paragraph frame (for example: “One cause is… because…,” “An effect is… which is supported by…”).
• Offer a small “term bank” with brief definitions; students choose terms that fit their evidence.
• For students needing support, allow paraphrasing options with guided prompts (“In Source B, it says…,” “A chart shows…”).
• Extension for advanced students: require an additional sentence explaining a feedback mechanism (using the term bank) and adding one more piece of evidence.
• EAL/SEN supports: short chunks for reading, explicit modeling of how to interpret the chart label/symbol, and visuals on the data snapshot.

Key concepts to emphasize during discussion and writing

• Climate change refers to long-term changes in temperature and other climate patterns.
• Greenhouse gases trap heat in Earth’s atmosphere; human activities can increase these gases.
• Effects can include rising sea levels, more heat extremes, changes in ecosystems, and impacts on human communities.
• Evidence matters: students should use the provided sources rather than relying only on personal beliefs.
• Alternate claims should be acknowledged and addressed using evidence from sources.
