With the end of Organic Chemistry with grade 10 we performed the Chemistry classic polimerization experiment: slime production from borax and polyvinyl alcohol. Then students were investigating the change of physical properties of the product of that reaction.
Grade 11 Biology students performed an enzyme activity experiment to determine the rate of reaction of invertase breaking down sucrose. We used a standard curve produced the week before to determine the concentration of reducing sugars using the acidified potassium permanganate decolonization method (sounds more complicated than it is, really).
IB Chemistry students were either researching Organic Chemistry reaction mechanisms or understanding ionic bonding and learning chemical nomenclature of ionic compounds.
Grade 12 Biology students are finishing the Genetics topic and learning about Genetic Engineering.
And on top of all this, we have a new fish (Hypostomus plecostomus) and some Elodea plant for experiments in the Biology school aquarium (experiments only performed with the plant, not the fish).
What a week!
