Crying in the name of Science

Crying in the name of science!

Year 12 biology students are completing Area of Study 3 practical investigation where they are testing the antibacterial effectiveness of tears compared to antiseptics and disinfectants.

Tears contain enzymes called lysozymes which have antibacterial properties and help destroy pathogens trying to get into your eyes! 

Shout outs go to Emily and Katie for letting us harvest their tears.
