Class: Grade 11-12 Date of lesson: 2012 Lesson title: Photosynthetic pigments, Stucture of Leaf Number in class: 15 and Chloroplasts Attainment range of pupils: all students are standard level Length of lesson: 80min

Learning objectives Learning outcomes (for all, most, some) - Identify the photosynthetic pigments All students will be able to: - Explain the relationship between the - recall that photosynthesis needs light action spectrum and the absorption - list the photosynthetic pigments spectrum of photosynthetic pigments in - identify the relationship between the action spectrum green plants. and the absorption spectrum of photosynthetic pigments in green plants. Assessment strategies Links to curriculum - Lab report - 3.8 Photosynthesis (IB) - Participation - 6.2.1 Photosynthesis (IGCSE) - Worksheet- puzzle - Fotosentez Lise 3 (MEB)

Prior teaching /learning Common misconceptions - Plants as a producers - Photosynthesis requires a green plant. - General formula of photosynthesis - Photosynthesis requires the presence of photosynthetic pigment, chlorophyll, found in green - Structure of leaf plants, but there are other pigments found in brown plants, red plants, and certain seaweeds that trap wavelengths of light that cannot be absorbed by chlorophyll alone. - Read more: http://intro.chem.okstate.edu/ChemSource/BIO/misco n.htm Key vocabulary Homework - Chlorophyll a - Worksheet - Chlorophyll b - puzzle - Carotenoids - Chromatography Pupils with special needs and support planned - Absorption Spectrum - more practices with worksheets - Granum - Thylakoid membrane Extension activities - Cyclic and - Non-cyclic reactions - Electron transport chain - Chromatography Cross curricular issues Chemistry Resources Risks and safety precautions - PowerPoint presentation - general lab safety rules. - Textbooks (MEB, IGCSE and IB)
