Ice core ! ... (10-12 years old)
The act of extracting the sample of ice called “ice sample carroting” - the shape of a
cylinder (which using a little imagination looks like large carrot) collected by drilling
deep into the ice cap.
Scientists analyze ice cores, because the ice is a memory of the climate and air bubbles
that are trapped are memories of the composition of the atmosphere.
