An Environmental Science Investigation
You will need: agar plates exposed in different parts
of your classroom (prepared in advance by your teacher), dissecting microscope
or hand lens, reference books
Your task is to examine the types of microorganisms
that can be collected in different parts of your classroom.
Without opening them, examine the microorganisms growing in the petri
dishes. Sketch and describe the different types of colonies you observe.
reference books to determine whether your colonies are mold or bacteria (mold
colonies are generally fuzzier and larger than bacterial colonies).
different microorganisms present in different areas of the classroom? Develop
some hypotheses for your results.
