IB Biology Y1 students model climate change

From November 8th to 20th, over 100 heads of state met to hold urgent talks on how atmospheric global warming may be limited to a 1.5 degree rise. In IB Biology, students modeled the effect of carbon dioxide on the enhanced greenhouse using simple laboratory apparatus. 

Simply by using a light source to represent the sun, two samples of the atmosphere were captured and then one spiked with enhanced CO2 – the latter generated by the well known degradation of a carbonate salt by a dilute acid.

This led to reflections by students on the paramount importance of high quality data on climate change, as world leaders tackle this great challenge.
