Swallow Hill Community College Faculty of Science – Key Stage 3 Scheme of Work Year 7 Module Title Casualty – topic 2 Development of medicines Lesson 10 POS R & C POS HSW 2.1 – structure of plants 1.1b(i) – scientific development 1.1b (ii) – how decisions are affected by society Lesson Outcomes Lesson Objectives Students will be able to label a diagram To be able to label a diagram of a plant of a plant and state what each part and relate each part to the relevant life does. Middle ability students will be process able to relate the parts to the 7 life To consider alternative medicines and processes. Higher ability will be able to consider how opinions have changed over link the structure to function. the years. Students will be able to give 3 examples of plants that can be used in herbal medicine Students will have considered different opinions on herbal medicine and form their own opinion. APP – assessment pieces to be collected from this lesson. Safety implications See notes on foxgloves Suggested Lesson Outline Starter Our friend in casualty gets a visitor, they bring him a bunch of flowers. What should you do with the flowers to keep them from dying? Phase 1 Very low ability- there are 2 worksheets for them to label a diagram of the plant and an extra one on roots if needed Medium ability – draw their own diagram / use the one provided to label the plant but also relate each part to the life processes in MRS GREN. A good opportunity here to revise the life processes from primary school Higher ability – AFL – they should be able to label a diagram of a plant – check they can do this, introduce xylem using the celery example. Could look at plant structure using the bioviewers (recommended) or microscopes. Look in more detail at what each part does, linking structure to function for the most able. Phase 2 (optional, depending on ability of group: card sort activity on linking life processes to plant structure) – could be done quickly on white board (higher), as a card sort (lower) or worksheet Phase 3 What plants can be used as medicines? See what students know. Show PowerPoint on herbal medicine. For less able groups the PowerPoint may need editing to contain less written information. Safety – please make sure students are aware that foxgloves are poisonous. St John’s Wort also stops contraceptive pill working (hopefully this shouldn’t be an issue!) As you go through the PowerPoint try to discuss with the students how opinions have changed over time about the use of herbal medicine and why. Discussion points for higher ability could be – why did herbal medicine become less popular in this country in the last 50 years? What herbal cures are still used? Why has herbal medicine become more popular recently? Plenary DVD clip 9C.2 from Year 9 science video vault on plant structure and maybe 9C.9 on root structure, could also show 9D.1 and 9C.8 about uses of plants. These clips are all only a couple of minutes. How does all this relate to our patient? Differentiation (Lower and Higher) See above Apparatus requirements Some wilted flowers and some sat in water, for higher ability celery that has been sat in dye to show xylem, bioviewers and slides on plant structure or microscopes. PowerPoint on herbal medicine, Year 9 video vault, optional worksheets on plant structure, optional card sort activity.
