today, revise with marcus his science as he is going to have his science SA 2 tomorrow. so now all i have in my mind is respiratory system, circulatory system, digestive system, plant system and skeletal system. muscles contract and pull the bones to allow movement. joints allow us to bend. not to mention, anus, gullet. exchange of gases in the lung. spine protects our spinal cord, skull protects our brains. ribcage protects our lungs. functions of leaves, roots, stems, stomata, chlorophyll, tubers, woody stem.

ha, i realise marcus is good at remembering things. he just has to apply what he learns to answer the questions. and if the question ask you to refer to the diagram, you must refer to the diagram. you must be able to compare and contrast.

actually, these are the skills i've been teaching and teaching my students. refer to the diagram, answer the questions. question ask you to describe the relationship, then you describe the relationship. question ask for factors that affect food production, then don't give me effects of food variation (obesity and malnutrition)

so answer the question, refer to the diagram. same, it's the same. i hope marcus can score 90 out of 100 for his science. well, that is the target i set him.
