This week has been intense for the grade 12 students, working frantically in the experimental part of their internal assessments. This is an area that students always find difficult, as they have to decide the investigation, design the experimental methodology and do a real research exercise, solving experimental problems with innovative solutions and feeling like true scientists at last. We have students investigating water retention properties of super polymers for agricultural applications, others investigating hydroponics and nutrient deficiencies, effects of antioxidants on the oxidation potential of oscillating reaction systems, calculations of the efficiencies of two different ester synthesis techniques, calculations of the activation energy of a chemical reaction using rates, observing the effects of detergent pollution in the rate of photosynthesis and finally observing the effect of a chemical present in smoke and ashes in the rate of germination of seeds.
Grade 11 students have finished Atomic structure in Chemistry and started Biochemistry in Biology.
Bring it on!
