Building Clear Paragraphs

Overview

Lesson 3 of 8 in Experiment Report Writers. Students examine how a paragraph develops one main idea, jointly construct a paragraph from experiment evidence, then draft their own paragraph about the method or observations.

Learning intentions

• WALT write connected paragraphs that explain one main idea clearly.
• WALT select relevant evidence from an experiment.
• WALT explain how evidence supports the main idea.
• WALT use linking words to connect ideas.

Success criteria

• I can write a clear topic sentence.
• I can include relevant evidence from the experiment.
• I can explain how details support my main idea.
• I can use linking words to connect my sentences.

Curriculum links

• Writing: create, organise and revise ideas in clear, purposeful paragraphs for an audience.
• Language features: use precise vocabulary, sentence structures and linking words to communicate meaning.
• Oral language: discuss, clarify and build on ideas before writing.
• Inquiry and critical thinking: use observations and evidence to explain what happened in an investigation.

Lesson structure (45 minutes)

1. 0–5 minutes – Hook and connect Open with the experiment paragraph hook. Display a short, jumbled paragraph about a familiar class experiment, such as testing which material keeps ice from melting. Ask: “What makes this easier to understand?” Students briefly identify the main idea and any missing connections. Remind students that this is lesson 3: today they will turn experiment notes into a connected paragraph.

2. 5–13 minutes – Teach the paragraph pattern Use the paragraph pattern slides to introduce the structure: topic sentence, evidence, explanation and linking sentence. Model thinking aloud: “My topic sentence tells the reader the paragraph’s focus. My evidence is what we observed or did. My explanation tells why that detail matters.” Highlight linking words such as first, next, because, therefore, however, as a result and finally. Explain that evidence must be accurate and relevant, not simply an interesting detail.

3. 13–22 minutes – Joint construction Show experiment notes on the board or in the deck. For example: “We wrapped one ice cube in cloth and left one uncovered. The covered cube stayed solid for longer. The uncovered cube became smaller quickly.” Ask students to help construct a paragraph about the method or observations. Record suggestions and negotiate wording. Prompt with: “What is our main idea?”, “Which observation proves it?”, and “How does that evidence support our idea?” Read the completed paragraph aloud and check it against the success criteria.

4. 22–27 minutes – Rehearse before writing In mixed-ability pairs, students choose either method or observations. They orally rehearse a paragraph using the four-part pattern. Provide the sentence openers prompt cards to students who need support. Partners take turns being the speaker and the listener; the listener identifies the topic sentence, evidence and explanation. Students may use their experiment notebooks, labelled diagrams or class data. Encourage precise vocabulary such as measured, observed, compared, melted, remained and tested.

5. 27–39 minutes – Independent paragraph draft Distribute the connected paragraph drafting worksheet. Students write one paragraph about the method or observations from the class experiment. The worksheet includes a planning strip, a paragraph frame, a model paragraph and a space for a final draft. Pause at two feedback points: after the topic sentence and after the evidence sentence. Confer with individuals or small groups, checking that the explanation answers “How does this detail support the main idea?” Students may type, use speech-to-text or dictate to an adult/peer before recording their ideas.

6. 39–45 minutes – Review and share Students reread their paragraph with a partner and underline the topic sentence, circle evidence and box the explanation. They highlight one linking word. Invite two or three students to read examples, including a method paragraph and an observations paragraph. Finish with the success criteria exit ticket slips. Students identify one criterion they achieved and one next step. Collect drafts and exit tickets for planning the next lesson.

Resources

• the experiment paragraph teaching deck
• the connected paragraph drafting worksheet
• the sentence openers prompt cards
• the success criteria exit ticket slips
• Experiment notebooks, observations, results or class data
• Board and markers
• Highlighters or coloured pencils
• Visual timer
• Headphones or device access for speech-to-text

Assessment

• Listen during pair rehearsal and joint construction for accurate use of evidence and explanations.
• Check drafts for a clear topic sentence, relevant experiment evidence, an explanation and linking words.
• Use exit tickets to identify students needing further support with paragraph organisation, evidence or cohesion.

Differentiation

• Provide an uncluttered worksheet, enlarged print, dyslexia-friendly sans-serif font, generous spacing and optional text-to-speech or adult reading of instructions.
• Offer paragraph frames, sentence starters, sequencing cards, oral-to-written rehearsal and an exemplar at two levels. Allow students to draw or orally record ideas before writing.
• For ADHD and autistic learners, display the four-part pattern visually, give one instruction at a time, use a visual timer, provide a quiet workspace and offer planned movement or sensory breaks.
• Work with a teacher-led group to orally build sentences. Reduce the writing load without reducing the thinking demand; students may type or use speech-to-text.

Extension

Students combine short sentences using precise conjunctions such as because, although, while and therefore. They vary paragraph openings, replace repeated words with precise scientific vocabulary and explain how their changes improve flow.
