Grade 12 chemistry students completed a lab experiment that involved finding the ion composition of two unknown solutions. Students performed various qualitative tests on the solution, such as precipitate, flame, and ash tests. Using the results of these tests, they were able to determine the elements in the aqueous solution.
The grade 12 Algebra and Geometry class started their adventure into vectors. Students learned about vectors, dot products, their properties, and the steps to check if two vectors are orthogonal. These new topics enhance their existing mathematics knowledge and will be applied in greater complexity in the following units.
