Cell Membrane Permeability—
Student Laboratory Kit
By: The Flinn Staff
Looking for a “Wow” from your students? The model organism Saccharomyces cerevisiae provides the drama in this study of the perme- ability of yeast cells and the function of the cell membrane . Using an indicator to observe which substances the cell membrane will allow, students discover that the cell membrane plays a vital role in regulating what goes into and out of the cell . The ability of substances to cross the phospholipid bilayer offers amazing visual evidence for facilitated diffu- sion and active versus passive transport . Kit includes reproducible student handouts, detailed background information, complete instructor’s notes with sample data and answers to all questions, and all chemicals and consumable supplies needed to perform the lab .
Complete for 30 students working in pairs. Super Value Kit is complete for 5 classes of 30 students working in pairs.
Yeast and Mold Soil Ecology—
Student Laboratory Kit
By: David Brock, Katie Loya, Roland Park Country School, Baltimore, MD and Mariel Torres, University of Maryland, MD
Soil is the foundation of all land-based life and is crucial to the health of any ecosystem . Discover more about soil ecology and the levels of yeast and mold in soil with this hands-on student laboratory kit! Students use PetrifilmTM strips and serial dilutions to quantify levels of yeast and mold in soil . Guided-inquiry activity allows students to create their own hypothesis, design and perform experiments, and analyze and interpret data .
Contains for 24 students working in pairs.
MudWattTM Classic Kit
Make a battery out of mud! This kit harnesses electricity that is released by common micro-organisms to create memorable learning experiences . Unlike most science kits, the MudWatt encourages you to use the scientific method alongside your creativity to design and conduct experiments . While forming hypotheses and testing them, learn about microbiology, engineering, energy and sustainability . The best part is that everything is completely reusable, including the packaging, which can be used as “food” for the micro-organisms!
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
One of the last frontiers in science today is the very dirt beneath our feet! 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.

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 resi-
due along with the paper towels and place into a Biohazard 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 .
