Update: we figured out why we have so many fruit flys: the recycled yogurt containers. Run the containers through the dish washer first before using them for science.
Keep the Patient Alive is a homeostasis lab. The Bio Co-op class did the lab today. We used 200 mL of water. The kids put the beakers into large yogurt containers. (Pretend the overflow is excretion and the ice and hot water added are IVs.) The lab took us about 45 minutes; however, I did a little instruction about properties of water, how to measure liquids with a graduated cylinders, and how to use a digital thermometer. These thermometers convert the TI 84 graphing calculator into a digital thermometer. It’s more responsive than a glass thermometer. This lab was a terrific, first lab. Take a look.
