Exploring the World of
Soil Protozoa—Student
Laboratory Kit
By: David Brock, Kate Brockmeyer, Kalyani Ravi and Leah Miller,
Roland Park Country School, Baltimore, MD
The organisms that inhabit the soil are responsible for all of the ecological cycles
that make life possible for plants and animals. In this kit, students will gain valuable
insight on protozoans—the “lions and tigers” of the soil—as they explore soil samples
and actually quantify the number of these organisms. An excellent way for students
to extract and explore the exciting world of soil protozoa.
Comes complete for 30 students working in pairs.

Winogradsky Column:
Biosphere in a Bottle—
Student Laboratory Kit
By: The Flinn Staff
Students observe microbial growth in their personally constructed Winogradsky
column with soil collected from their surroundings. Repeating the soil microbe-growing
technique—made famous by the Russian microbiologist, Sergei Winogradsky—is
fun and motivating. Over a several month incubation period, students will witness
an array of protozoa, fungi, bacteria and algae as their Winogradsky column goes
through its successive stages. Includes enough materials for 10 Winogradsky
columns (chemical nutrients, wooden stirring sticks and teaching instructions).
Complete for 10 student groups. You supply the mud! The 10 columns included in
the kit can be reused.

The Glowing Germ
Contamination—
Demonstration Kit
By: Rhonda Reist, Olathe North H.S., Olathe, KS
It’s amazing how fast germs can be spread around your classroom. Place a small
quantity of glowing lotion on a frequently touched object without the students’
knowledge. During a discussion of how disease causing microorganisms are transmitted,
tell the students that you’ve contaminated one object in the lab before class
and want to see how far the contamination has spread. Turn off the classroom lights
and turn on one or more ultraviolet (black) lights. Anywhere that the fluorescent
lotion has been spread it will glow. Students will be amazed at how contaminated the
lab is. A perfect activity for illustrating the importance of good laboratory hygiene in
biology, microbiology, and chemistry classes alike. You’ll be guaranteed a classroom
full of clean hands. Includes an eight-ounce container of the lotion (enough for many
classes) and complete use instructions with presentation tips.
Concepts: Fluorescence, laboratory hygiene, ultraviolet light.
Time Required: One class period Materials Provided: Glowing Germ lotion.
Note: An ultraviolet light and a completely darkened room are necessary.

Microbes Around Us—
Student Laboratory Kit
By: The Flinn Staff
Yuck! That’s what your students will say when they see microbes growing on their
agar plates. Students will be amazed at the microbes they find on “clean” surfaces!
Once additional testing is completed, students will determine whether antibacterial
products really work. The step-by-step directions provided will help you prepare for
a safe and involving first microbiology laboratory.
Student experimental designs and lab group group size will determine how many
kits you will need. The preparation of sterile agar-filled Petri dishes requires the use
of an autoclave or pressure cooker.

Clean Up Microbiological Spills
1. Pour 70% isopropyl alcohol or 10% household bleach on any broken glass or contaminated
surfaces.
2. Cover spill area with paper towels, and saturate with additional alcohol or bleach
solution. Wait 30 minutes.
3. Wearing rubber gloves and using tongs, pick up all glass or residue along with the
paper towels and place into a Bio hazard bag.
4. Loosely close the biohazard bag, place it in the autoclave and sterilize the contents.
Follow safe disposal procedures for the biohazard bag.
5. Wash the spill area again with bleach or alcohol and wash hands thoroughly.
