Strong Reasons Evidence

Overview

Lesson 6 of 14 in Persuade Through Time. Students investigate how a change over time can be supported by historical evidence, then build a simple claim–reason–evidence chain about a familiar change in Australian life.

Learning intentions

• WALT connect a reason with relevant historical evidence.
• Students will identify a claim, reason and evidence.
• Students will explain how evidence supports a reason.
• Students will listen, discuss and build ideas collaboratively through inquiry.

Success criteria

• I can state a clear claim about a change over time.
• I can give a reason for my claim.
• I can choose evidence that matches my reason.
• I can explain how my evidence supports my reason.

Curriculum links

• Creating short persuasive texts for a familiar audience and purpose.
• Understanding how texts use ideas and details to influence an audience.
• Listening to and contributing relevant ideas in group discussions.
• Asking questions, investigating sources and communicating an understanding of change over time.
• Using evidence from sources to support an explanation.

Lesson structure (45 minutes)

1. 0–5 minutes – Hook and retrieval

Display a before-and-after image, such as a classroom from the past and a classroom today, using the opening comparison slide. Ask: “Which classroom would you choose? What makes you think that?” Students turn and talk, then share one observation. Briefly revisit the previous lesson’s meaning of claim and reason.

2. 5–12 minutes – Model the chain

Open the claim–reason–evidence teaching slides. Explain that a claim is what we think, a reason tells why, and evidence is a detail from a source that helps prove the reason.

Model aloud: “Classrooms today are more comfortable. They have better lighting, because photographs show large windows and electric lights.” Point to the source detail and say: “This supports my reason because it shows how the classroom was lit.” Invite students to help identify the claim, reason and evidence.

3. 12–17 minutes – Guided source investigation

Show three or four simple class sources in the source investigation slides: photographs, a short child-friendly caption and an object or record connected to changes such as transport, communication, school life or home life. Ask: “What do you notice? What does this source tell us? Which reason could it support?”

Record student observations using the sentence frame: “This evidence supports the reason because it shows…”

4. 17–30 minutes – Collaborative evidence sort

Place students in groups of four or five. Give each group one change to investigate and distribute the claim–reason–evidence investigation sheet. Provide each group with a small set of teacher-prepared source excerpts or images.

Groups choose a claim and reason, then select the strongest evidence for that reason. Students may draw, point, dictate or write. Encourage collaborative construction: one student reads the source, one explains it, one records and one checks the match. Confer with groups using: “What is your reason? Which part of the source helps you know that?”

5. 30–37 minutes – Explain and challenge

Groups prepare a short oral explanation using the frame: “We think ___ because ___. Our evidence is ___. It supports our reason because ___.” Groups share with a partner group. Listeners respond: “Your evidence matches because…” or “We wonder if…”

For students ready for extension, ask them to rank two or more pieces of evidence from strongest to weakest and explain their ranking.

6. 37–43 minutes – Individual response

Students complete the final section of the claim–reason–evidence investigation sheet independently. They draw or write one complete chain about their group’s change. Encourage the use of the word because to connect the evidence to the reason. Students who need support may orally rehearse their response with the teacher or a partner before recording it.

7. 43–45 minutes – Plenary and exit check

Return to the final reflection slide. Ask: “What makes evidence useful?” Invite two students to complete: “Evidence is relevant when…” Collect the worksheets or listen to two individual responses as a quick check for understanding.

Resources

• the introduction, modelling, source investigation and reflection deck
• the claim–reason–evidence investigation sheet
• Three or four historical photographs, object images or short source excerpts
• Large paper or whiteboard
• Markers, pencils and coloured pencils
• Group tubs or folders containing one change and its source set
• Optional sticky notes for recording observations
• Teacher-prepared preselected evidence cards for students requiring greater support

Assessment

• Listen during group discussion for students who distinguish a reason from evidence and select evidence that matches.
• Check each worksheet for a connected claim–reason–evidence chain and an explanation using “because”.
• Note whether students can explain why their evidence supports their reason; use this to plan the next lesson’s modelling and conferencing.

Differentiation

• Provide preselected evidence cards, fewer source choices and a completed example for students who need support.
• Use the graphic organiser on the claim–reason–evidence investigation sheet, sentence frames, oral rehearsal and teacher conferencing.
• Support EAL learners with visual sources, gestures, repeated key words and partner talk before writing. Accept drawing, labelling, scribing or recorded oral responses.
• Allow collaborative construction and mixed-ability grouping. Extend confident students by asking them to rank evidence by relevance and justify their ranking.
