Problem
Which type of medicines (including liquids and tablets)
eliminate the most bacteria?
Hypothesis
If different types of medicines including liquids and tablets for
children and adults’ cold and infections are used on the bacteria
then the adult antibiotics tablet for adult will have more of an
affect on the bacteria that eliminates more bacteria which will
make the bacteria have less colonies than the bacteria without
medicine.
