BACTERIA & MICROBIOLOGY, CONTINUEDBioassay Experiment— Student Laboratory KitThis cooperative class experiment deter-mines the effect of concentrations of salt solutions on lettuce seed growth and devel-opment. With the results, students predict possible environmental effects of agricul-tural runoff, drilling and mining wastes and industrial discharge as well as the “toxicity” of ordinary table salt! FB1881 I $73.50Using Bacteria To Clean Clothes? Genetic Engineering in Action—Student Laboratory KitStudents investigate whether detergents with GMO-derived enzymes will “clean clothes” better than those without by comparing the ability to digest proteins (gelatin). Suggestions are included to make this into a cooperative class project by assigning groups different variables. Super Value Kit includes materials for 75 student groups.2 options available at flinnsci.com$26.20–$51.053M® Petriflim™3M® Petriflim™ stays refrigerated for 18 months, and 50 plates occupy the space of one Petri dish. Ready to use with various media, Petrifilm “plates” have sterile culture media between two plastic film sheets that you separate for inoculation then reseal and incubate. Growth occurs on the media film, and results are visible through the film. 3 options available at flinnsci.com$71.95–$85.60Biofilms—Student Laboratory KitBiofilms, or “slime cities,” thrive wherever there is water. This hands-on kit lets students treat microscope slides with substances and immerse them in biofilm-rich media. The coated slides are removed, stained and examined with a microscope to detect biofilm growth. The effects of different treat-ments on biofilm growth are compared and contrasted.FB1886 I $51.25MIDDLE SCHOOL LIFE SCIENCEGrowLab II®—Compact Indoor GardenThis is the plant stand you need for limited space.
