Lipids Overview

Overview

In this lesson, students are introduced to lipids and their role in the body. They will classify fats, oils, and waxes, and practise differentiating saturated from unsaturated fats using everyday examples.

Learning intentions

• Students will describe what lipids are and where they are found in food and the body.
• Students will categorise lipids into fats, oils, and waxes using simple properties and examples.
• Students will distinguish saturated fats from unsaturated fats using their typical sources and characteristics.
• Students will explain, with evidence, why the type of fat matters for health.

Success criteria

• I can correctly name and give an example of a fat, oil, and wax.
• I can describe the key difference between saturated and unsaturated fats.
• I can sort given food examples into saturated and unsaturated categories.
• I can justify my sorting using simple scientific reasoning (e.g., typical food sources and “when/why” a fat is more likely to be saturated or unsaturated).

Curriculum links

• Biology: nutrition in humans, including the role of nutrients in the body
• Health and lifestyle: linking food choices to health outcomes
• Working scientifically: using evidence to support explanations and making reasoned conclusions

Lesson structure (60 minutes)

1. 0–5 mins: Retrieval starter Students recap the unit so far (carbohydrates and proteins) using quick oral prompts and a 3-question “thumb check” (no writing required). Teacher links back: nutrients → energy and body function → need to understand lipids next.

2. 5–15 mins: Introduce lipids (short, clear input) Teacher explains that lipids are a broad group of nutrients that include fats, oils, and waxes. Students follow a dyslexia-friendly handout with short sentences and an image-based “lipid map” (teacher-led). Key idea: different lipids have different physical properties and roles.

3. 15–25 mins: Categorise fats, oils, waxes In pairs, students sort provided picture cards (e.g., butter, olive oil, candles/wax, nut paste, animal fat) into fats, oils, waxes, with a one-sentence reason for each category. Teacher circulates, checking vocabulary and misconceptions (e.g., “wax only exists in candles”).

4. 25–35 mins: Saturated vs unsaturated (guided reasoning) Teacher models a simple comparison: saturated fats are commonly found in animal-based foods and certain solid fats; unsaturated fats are more common in plant-based oils and some soft foods. Students annotate a comparison table (two columns) using sentence starters: “I think this is saturated because…” and “I think this is unsaturated because…”

5. 35–48 mins: Evidence task (food sorting + justification) Groups of 3–4 use a set of food labels/cut-outs (or teacher-prepared cards) to sort foods as “likely saturated” or “likely unsaturated.” Each student completes a quick written justification (1–2 sentences) linked to the success criteria. Teacher checks that students can explain their reasoning, not just guess.

6. 48–55 mins: Class discussion + misconceptions check Teacher facilitates a structured share-out: each group presents one food and explains their reasoning. Students use a “challenge phrase” protocol: “Can you explain how you decided…?” This targets deeper understanding and addresses common errors (e.g., assuming all fats are unhealthy, confusing “oil” with “unsaturated” in every case).

7. 55–60 mins: Exit ticket (assessment for learning) Students answer two prompts:

• “Name one difference between saturated and unsaturated fats.”
• “Sort: butter, olive oil, nuts, cheese (choose likely saturated/unsaturated and give one reason).” Teacher reviews for next-lesson planning.

Resources

• Dyslexia-friendly worksheet with lipid map and short sentence frames
• Picture card set: fats, oils, waxes examples
• Comparison table template: saturated vs unsaturated (two-column, large font)
• Food label/cut-out cards (or prepared teacher cards) for sorting
• Pair sorting recording sheet (space for 1–2 sentence justifications)
• Sentence starters and misconception prompts
• Exit ticket slips
• Coloured pens or highlighters for categorisation
• Projected slide/board example for teacher modelling

Assessment

• Formative: teacher observes pair sorting and checks the one-sentence reasons
• Formative: group justification during the evidence task (accuracy + reasoning)
• Summative-ish for this lesson: exit ticket differentiating saturated and unsaturated fats

Differentiation

• Support: provide a completed example table for one “model food,” plus a word bank (fat, oil, wax, saturated, unsaturated, plant, animal, solid, liquid)
• Support (reading): use shorter handout sections, larger font, and allow students to discuss answers before writing
• Extension (advanced learners): ask students to add a “strength of evidence” comment to their justification (e.g., “My evidence is strong/medium because…”), and to compare two similar foods and explain why one might be more saturated
• SEN/EAL: offer visual supports (icons for solid vs liquid, plant vs animal) and sentence frames; allow oral responses if writing is a barrier
