Literacy and Learning: Learning through talk: Comparing genetic diagrams, and impacts ion genetic engineering Discussion on timeline showing evolution 2A.M1 1. Teachers give a simple introduction to natural selection could involve the study of short and long-necked giraffes. 2. Learners draw a fictitious timeline, including pictures and genetic diagrams where appropriate to show how the species evolved long necks over a period of time. The key details of natural selection could be used to annotate the timeline 2A.D1 Discussion on different environments and species ability to adapt to survive Discussion on the five kingdoms Discuss and collaborate on producing ideas about the ways that humans affect the Earth, and the plant/animal species. How our actions have changed the earth Small/large group activities – practical 1 By CHu Syllabus References: practical work 2. Emphasis on key words use and meanings 3. Availability of a dictionary 4. Use of Google translate PP: 1. Regular assessment of student progress 2. Encouragement in class activities LAC: 1. Use of Collins differentiated work tasks available Boys underachievement: 1. Encourage full interaction in activities 2. Identify roles in group work 3. Peer supporting activities Assessment for Learning Opportunities: 1. Students have targets which they know and understand 2. Students know regularly at what level they are working in relation to these targets 3. Students know how they can improve their working at level so as to achieve their targets 4. The students have access to level/grade descriptors, e.g. in their books or on classroom walls, and they understand them, and there is reference to them within lessons 5. There are exemplars of good work available of different types which we can show to students and which, in particular, illustrate level/grade requirements 6. Schemes of work/lesson plans all make 1. Learners use the example of giraffes or other examples such as the peppered moth or an extinct species to produce a presentation which evaluates the role of genes and the environment on the survival of species. 2.http://www.biologycorner.com/worksheets/pepperedmoth.html - an interactive activity which illustrates how different populations of peppered moth change depending on environmental factors and predation. 2A.P3 1. Learners are introduced to different environments – this can be carried out as a brainstorm activity or as an outdoor practical activity which is extended by learners listing the types of organisms found in each environment. 2.Learners group organisms depending on their feeding relationships 2A.M2 1. Learners produce display work that shows how food chains interlink to form food webs. 2. Learners annotate food webs to give details of how organisms show interdependence. Further research using ICT will provide examples other than feeding relationships e.g. humans use some plants to produce medicines. Learners add these details to their display work or present their findings on interdependence as a separate poster or information booklet. 2A.P2 1. Introduce learners to the five kingdoms using a PowerPoint® presentation with pictures that give examples of organisms from each group. Learners work in pairs to place each organism into one of the five kingdoms, giving a reason for their answer. This work could be adapted where each group of learners is given a list of organisms to research with the aim of classifying them depending on their characteristics 2. Results are collated and pooled so that details of all classification groups are covered. 3. Review Key Stage 3 knowledge of the vertebrate groups 2 By CHu investigations- developing team work Use of roles within groups Learning from text: Use research and put information into own words Use of text books for research- students to gather appropriate information they required Use of library books Use of Principles Of science text books Learning through writing: Presenting work as: reports, leaflets, newspaper articles, posters Numeracy Links: Calculating using Punnett squares to illustrate genetic inheritance of specific characteristics different populations of peppered moth writing word equations then symbol equations then balancing them Calculating averages from practical results from Construct graphs lined/ bar/ curves from Cross-Curricular Links: Geography: looking at different areas within the country, then different countries environments the changing of some environments through human actions. specific reference to AFL 7. Learning objectives are differentiated and levelled/graded 8. Lesson observations show that each teacher is in “AFL mode”, i.e. always discussing their work with students and helping them see how they can improve in terms of level/grade descriptors and achieving targets. 9. There is evidence that teachers have the skill of asking the students the type of questions, both individually and to the whole class, that enables them to understand how they can progress, and where relevant lead them to see how they can move on to achieve higher levels/grades. 10. There is evidence that both peer and self assessment relating to the learning objectives are occurring in lessons as appropriate 11. There is the evidence of AFL comments in the marking of students’ work. 12. AFL is also being used to adjust schemes of work, lesson plans and overall teaching in the light of analysis of the ascertained responses of students Student Leadership Opportunities: Group work roles- manager/ leader during practical activities Organising a small group for a presentation to the class on Extension/Enrichment Opportunities: Working at the higher distinction grades, to evaluate, synthesise learning using flash cards and mini whiteboards which learners can use to categorise the organism on the cards that are shown by the teacher. 4. Learners construct a board game that focuses on the main characteristics of the vertebrate groups (reproduction methods, oxygen absorption methods and thermoregulatory processes). The game may include pictures of the vertebrates that could be ‘bonus squares’ for example with questions and answers also relating to classification groups.
