My one had little dots on it and I wonder if bacteria will grow on it more?
The next few weeks it grew more bacteria on it. On one side it had Squiggly lines and on the other side it had Black dots.
I like the way you add the photos are rally good
ReplyDeleteHi Alyssa-Rose, well done on having each step in the method on a new line. It makes it easier for someone else to follow your instructions. I like how you included a description of what the bacteria looked like. Next time, make sure all your writing is in the same font.
