We are kicking off Quarter 2 in Science Lab by watching how germs spread in our classroom. We did the same experiment as in the video below from Mark Rober. In our case we played Head Up Seven Up and tried to trace the UV powder back to the original couple of students.

This next video from MythBusters show has far the germs from our sneezes can travel!

How can the spread of a communicable disease be reduced?

Why might it be important for scientists to determine patient zero?
