Agroup of science students collect bacterial swabs from several locations inside their school. the collected bacterial swabs are spread over an agar-filled petri dish and bacteria colonies are grown. the students then install hand sanitizer dispensers throughout the school. one month later the students collect bacterial swabs from the same locations around the school and bacteria colonies are grown. bacterial growth is counted for each sample and the data is compared.
what might be the question the students are asking in this experiment?
a) how long does bacteria live
b) why does bacteria grow at schools
c) does my school have more bacteria than the average school?
d) does the addition of hand sanitizer dispensers throughout the school reduce the amount of bacteria?
