NATURAL SELECTION AND ANTIBIOTIC RESISTANT BACTERIA
Kit #904S — Developed by SEPUP

Why is it important to take an antibiotic as prescribed? Students model the effects of
antibiotics on the population of disease-causing bacteria during an infection . During the
simulation, some groups complete the full course of antibiotics, while others miss doses . They
then graph populations of more-resistant and less-resistant bacteria . Students observe the
selection of more-resistant bacteria that can take place if antibiotic treatment is intermittent or
discontinued prematurely . Through this activity, students learn why it’s important to take “the
full course” of antibiotics .
Accommodates unlimited classes, each with 16 groups of two students.

PHOSPHATE IN FRESH WATER
TEST

Kit #19-1-PH
A major cause of water pollution is too much phosphate .
Students begin to understand and appreciate why some
areas of the country have restricted the use of detergents
that contain phosphates, due to the problems caused by this
“non-biodegradable” substance . The presence of phosphate is
indicated in this qualitative test when the water sample turns
blue .
Accommodates 10 groups of students per class and a maximum
of 150 tests.
