6B have been
exploring the wonderful world of micro-organisms.
We have discovered
that yeast is a micro-organism used in bread making. It gives off a gas called
carbon dioxide that makes bread rise.
We have also grown
our own mould and found that mould grows best in a warm environment. We
discovered that mould was studied by scientists who used it to develop
important medicines. These discoveries
have saved many people’s lives over the last 80 years.
