Unit6 cross curricular connection学案 2026-2027学年沪教版八年级英语上册

Unit 6 Wisdom counts 跨学科探究课学案 2026-2027学年沪教版八年级英语上册 Class __________ Name __________ Date __________ 教材定位 第96页 History 建议课时 40分钟 本课聚焦 比较实物、文字与技术证据，形成与证据强度相称的历史判断。 完成标志 完成一份带证据和保留意见的博物馆展签。 一 历史侦探的第一问 4分钟 Someone says, “We found the remains of an ancient city, so every detail in the story about it must be true.” Do you agree? YES / NO / NOT SURE What could the remains show? What might they not show? ________________________________________________________________________________ 二 读懂三种取证办法 7分钟 Read Exploring history: piecing the puzzle together on p. 96. Complete the chart in short phrases. Method An example in the text What can it help us learn? Study objects from the past __________________ How people ____________________. Study written sources __________________ What people ____________________. Use carbon-dating __________________ The ____________________ of a material. Use DNA evidence __________________ Information about ____________________. Key question: Why should historians compare different documents instead of trusting just one? ________________________________________________________________________________ ________________________________________________________________________________ 工具词 evidence 证据；source 资料来源；claim 待检验的说法；support 支持；prove 证明；reliable 可靠的。 读证据时问四句 Who made it? When was it made? What can it show? What can it NOT show? 一句提醒 A source can be useful without being complete. 有用的证据也可能只说明事情的一部分。 三 调查一则地方故事 12分钟 课堂模拟材料 以下River Town、年份和资料均为本课虚构的证据练习，不是真实考古发现。不同资料的内容需要互相核对。 Museum claim to check: “In Year 20, a boy named Lin rang the town bell at night and saved EVERY family before a flood.” Source A A story written in Year 120 A local storyteller wrote that Lin, a brave boy, rang the bell and saved every family in Year 20. The writer was not alive during the flood and did not name any sources. Source B A resident’s diary from Year 20 “Last night, I heard the bell. I took my children across the bridge before the water rose. I could not see who rang it. Some families were still leaving when we crossed.” Source C A town repair record from Year 21 “After last year’s flood, workers repaired the bridge and the bell tower.” The record lists materials and costs, but it does not name the bell-ringer or count the families who escaped. Source D A wooden support from the bell tower A laboratory report gives the wood an estimated age range consistent with Years 5–30. It does not show who used the bell or when the support was put into the tower. 1. Which source is an eyewitness account（亲历者记录）? ______ 2. Which source was produced 100 years after the claimed event? ______ 3. Which source uses scientific testing? ______ 4. Which TWO sources best support that a flood occurred around Year 20? ______ and ______. Give one detail from each. ________________________________________________________________________________ ________________________________________________________________________________ 5. Does an old piece of wood prove that Lin rang the bell? Explain one missing link in the evidence. ________________________________________________________________________________ 四 给结论划定边界 9分钟 Use the sources to judge each statement: S = supported; U = not yet established（尚未证实）. “Not proved” does not automatically mean “false”. Statement S or U Source and reason 1. A flood occurred around Year 20. _____ ___________________________ 2. The diary writer heard a bell at night. _____ ___________________________ 3. The bell-ringer was certainly Lin. _____ ___________________________ 4. Every family escaped because of the bell. _____ ___________________________ A classmate says, “Source C is official, so it can prove everything.” Write a reply with one strength and one limit of this source. ________________________________________________________________________________ ________________________________________________________________________________ 五 写一张负责任的展签 6分钟 Write 45–60 words for the museum. Include one supported conclusion, TWO named sources, and one point that is still uncertain. 支架 Source … describes …, and Source … records … . Together, they suggest … . However, we still do not know … . ________________________________________________________________________________ ________________________________________________________________________________ ________________________________________________________________________________ ________________________________________________________________________________ ________________________________________________________________________________ 六 下一步该找什么 2分钟 One extra source I would look for: __________________________________________________ It could help answer: ______________________________________________________________ 自评 [ ] 我说明证据出处 [ ] 我区分“支持”与“证明一切” [ ] 我保留仍不确定的信息 参考答案与证据分析 一与二 教材阅读 一 建议选NO。城市遗址支持当地存在古代聚落，但不能自动证实故事中的对话、动机或全部事件。 二 实物例子：tools / coins / clothes / artefacts；帮助了解how people lived。文字例子：official documents / diaries / letters / notebooks / photos；帮助了解what people did, said and thought。 碳测年：paper / wood；age。DNA：DNA from relatives / the Richard III example；family relationships / family trees。按照教材提供的功能概括即可，不要求掌握技术原理。 比较资料的原因：Old documents do not always give correct or complete information. Comparing sources helps historians check what really happened. 三 模拟证据调查 1. B。日记作者记录自己听见铃声并带孩子离开的经历。亲历者也有视野限制：他明确说没有看见敲钟者。 2. A。晚100年写成，且未交代来源；可说明后来的故事版本，却不足以证实姓名和“所有家庭”。 3. D。实验室报告使用科学检测，但给出的是木材年代范围，不是某个具体人物的行动记录。 4. B and C。B记载Year 20水位上涨、家庭撤离；C在Year 21记录修复“上一年洪水”造成的损坏。两条不同资料在时间和洪水事实上相互支持。 5. No. The wood’s age does not identify the bell-ringer or tell us when it was installed. 材料年代、安装年代和使用者是不同问题。 四 结论的强弱 1. S，B和C共同支持。2. S，B直接记载其所听到的铃声；这里的结论限定为“日记作者的记载”。3. U，只有较晚的A明确命名，缺少独立核对。4. U，B只涉及自己的家庭和部分他人，C也没有总人数，不能推出“所有家庭均因铃声获救”。 参考答案与历史思维评价 四 官方记录也有范围 示例：Source C records repairs after a flood. However, it does not name the bell-ringer or count the families who escaped. It cannot prove the whole story. “官方”不等于完整无误；“不完整”也不等于无价值。 五 博物馆展签示例 Source B describes a family leaving after a bell rang, and Source C records repairs after a flood. Together, they support a flood around Year 20. However, we still do not know who rang the bell or whether every family escaped. Lin’s story needs more evidence. 语言要点 support / suggest表达与证据强度相称的判断；however引出仍未解决的问题。避免把“可能”写成“肯定”，也避免因为存在未知就否定已经得到支持的部分。 展签评分 8分 判断标准 结论 2分 提出受到材料支持的结论；不把整则传说直接写成事实。 证据 2分 点明两条来源，并正确说明其内容，每条1分。 边界 2分 写清仍未知的问题；不把“未证实”等同于“已证明为假”。 表达 2分 信息连贯、读者易懂；词语能表达不同的确定程度。 六 下一步调查 示例1：A second diary from someone near the bell tower. It might help identify the bell-ringer. 需检查是否独立记录。 示例2：Records of families before and after the flood. They might help check how many families survived or moved away. 示例3：A dated record of the bell tower’s construction. It could help connect the old wooden support with the tower. 课堂收束 追问：“What evidence would make you change your mind?” 要求学生说明改变判断所需的新证据，可先用中文解释。 Unit 6 | 学科网（北京）股份有限公司 $
