BACTERIA & MICROBIOLOGY, CONTINUEDBacterial Pollution (Coliform)—Super Value Laboratory KitStudents determine the presence or absence of coliform bacteria (indicative of the presence of untreated sewage and potentially pathogenic bacteria) in water supplies. By observing a dramatic color change that occurs in a lactose broth medium, students will determine whether coliforms are present. Super Value Kit includes 75 tubes of lactose broth medium with chlorophenol red indicator, sterile transfer pipets and instructions.FB2058 I $137.45Effects of Disinfectants and Antiseptics on Bacteria—Student Laboratory KitStudents thoroughly investigate and compare several antiseptic and disinfectant products, such as soap, alcohol and bleach. With the buzz in the media about bacterial resistance, you will hold a captive audience while discussing this important topic!FB1793 I $71.70FLINN SCIENTIFIC I MIDDLE SCHOOL LIFE SCIENCEViruses and Bacteria PosterPoster provides detailed drawings and actual photography of harmful bacteria and viruses. Examining the poster helps students identify these agents and learn how they cause harm to humans. Poster measures 35" W x 27" H. Laminated version available.FB1677 I $14.00Bacteria in Milk—Super Value Laboratory KitHow much bacteria grows in refrigerated milk or milk that sits out for a few hours or a day? Using a resazurin color reaction, students test refrigerated milk, boiled milk and room-temperature milk to determine and compare relative bacterial conditions. Super Value Kit is complete for five classes of 30 students working in pairs.FB2057 I $50.20What’s Living in YOUR Shower? Student Laboratory KitIntroduce students to environmental microbes “hiding in plain sight” with a hands-on culturing activity. Students develop sterile techniques, collecting and culturing samples from various surfaces. Students observe and diagram the result-ing microbial colonies to compare growth characteristics and discover the diversity of microbes and their unique “personalities.”FB1752 I $41.95Sam ’n’ Ella’s Café—Simulated Food Poisoning Laboratory KitDiscuss safe handling of food after students “eat” at Sam ’n’ Ella’s Café in a true-to-life simulation. Students select food from six categories and then test the “food” (water) to see who and how many people are “sick.” Students become food detectives to determine which food is contaminated and what “bacterium” may be to blame.
