Sophia - Environmental Science - Unit 1 Challenge 1
1 — Science & The Scientific Process
Identify the steps of the scientific method in a given situation.
Alexander Fleming made a great discovery in the 1920s. While cleaning some glass plates
upon which he had been growing bacteria, he noticed one plate had grown mold and the
bacteria was gone.
Which of the following activities corresponds with the conclusion step of the
scientific method?
a.) Fleming determines that penicillin (from mold) can be used to treat bacterial infections.
b.) Fleming wonders if there is a causal relationship between the mold and the disappearance
of the bacteria.
c.) Fleming introduces liquid mold to some bacteria cultures and no mold to others.
d.) Fleming hypothesizes that if bacteria are exposed to a certain kind of mold, the bacteria
will die.
2 — Environmental Science
Classify an element as either biotic or abiotic.
Which of the following is an abiotic element in this image?
a.) Moss
b.) Grass
c.) Rocks
