We will study mercury.

Students learn that mercury has been used by humans since ancient times and that methylmercury still exists.

They are asked to touch the ore (cinnabar), which contains mercury sulphide.

The ore is heavy and chunky because of the mercury content.

First of all, we learn about DNA.

DNA has been successfully extracted.

The white, fuzzy stuff is the DNA.

We will study about chromatography.
