reflections of term 3......

this term is a very fast one but at the same time a fun-filled and enriching one. Although we did not have many lab lessons where we do experiments, i learnt a lot of things during lessons in class. for example, photosynthesis and respiration, pressure and also on cells. Even though photosynthesis, respiration and cells have been taught in primary school, i have been introduced to a more in-dept knowledge of all those topics. for example, in respiration, there is such a thing called aerobic respiration which i did not learn in primary school.
in term of test, i must say that i am both satisfied and unsatisfied. Satisfied because i managed to score a A2 for is and unsatisfied because i miss A1 by one mark for all three tests. I hope i can do well for my EOYs.

here is a video of respiration:
