This week in Science we built a massive wave machine to demonstrate this difficult concept. Primary students were invited for demonstrations and enjoyed the awesomeness of Physics.
IB Biology students were using a colorimetric method to measure the concentration of reducing sugars and investigate rate of enzyme action. Also, in an outdoor Chemistry lesson we received the unexpected visit of some goats who helped us to figure out how intermolecular forces work.
The rest of the grades were covering theoretical concepts in preparation for more exams to come next week before Christmas.
We deserve the holiday!!!
