Flinn STEM Design ChallengeTM
Students build a model of the nephron, the filtering unit of the kidney, and investigate its ability to filter various substances out of simulated blood. Simulated urine is analyzed using common urinalysis tests for color, clar- ity, pH, salt crystals and glucose. The results help students understand the importance of urinalysis as a vital tool in diagnosing physi- ological health conditions. Includes enough materials for 30 students working in pairs. FB1859 | $62.85
Students test five different simulated urine samples for five different common urinal- ysis factors. Results are then compared. Preliminary indications about the health of the tested individuals are explored. One urine hydrometer is included in the kit and

With the Flinn STEM Design ChallengeTM Digestion Connection, students discover
the inner workings of the stomach and its digestive capabilities. Then your students are challenged to design a pill coating that can withstand the stomach’s harsh acidic environ- ment, with a pH so low it can dissolve iron nails! By applying relevant concerns, students engage in a fun activity that integrates biological and engineering skills. Complete for 30 students working in pairs.

Functioning Lung Model—Demonstration Kit
Extra large, unbreakable, clear plastic housing makes this func- tioning lung model the best available. The functioning lungs can be seen from the back of the classroom as you demon- strate the principle of differential air pressure. The use of rubber stoppers on the ends of the bronchus makes replacing worn out lungs much easier than traditional models using string or rubber bands. The handle on the durable, latex diaphragm allows for easier expansion of the balloon lungs during opera- tion. Measures 53⁄4" x 11", comes assembled with instructions.

Exercise, CO2 and Respiration—
Laboratory Kits
How and why do athletes train to increase their breathing efficiency? Students will answer this question and explore the complex biofeed- back mechanism by which the body uses the production of CO2 and to regulate breathing.
