Students learn about various crystals, such as kidney stones, within the human body. They also learn about how crystals grow and ways to inhibit their growth. They also learn how researchers such as chemical engineers design drugs with the intent to inhibit crystal growth for medical treatment purposes and the factors they face when attempting to implement their designs. A day before presenting this lesson to students, conduct the associated activity, Rock Candy Your Body.

Health Science 20 - Excrement Lab & Case Studies - Dakota de Caux In order to explore diagnostic techniques and pathologies associated with the urinary and digestive systems, I had students complete an excrement lab activity and diagnose case studies related to the samples that they analyzed. During the lab, they conducted macroscopic and chemical analysis of teacher created urine and stool samples. Based on their data, they were asked to discuss potential pathologies that could be causing they symptoms that they observed. Once the lab reports were complete, each student was assigned a case study that was connected to a specific urine or feces sample and were asked to come up with a diagnosis that they would present to the class. Students were given two class periods to conduct their research and put together their presentations. This activity gave students the opportunity to apply their knowledge of the digestive and excretory systems while also making connections to real life medical applications through the completion of artificial excrement analysis and case study diagnosis. Students were noticeably engaged during all segments of this activity. The knowledge and skills that students acquired will help them be critical when discussing their own medical results with health care professionals. The case study portion of the activity encouraged students to locate reliable sources and recognize the need for additional test results or patient history in order to determine a diagnosis because certain excrement results can suggest numerous pathologies. We also discussed the importance of patient honesty in the selection of a correct diagnosis. This learning activity and assessment strategy encourages the development of critical thinking, collaboration, communication, and computer/digital technologies.
Purpose:
The purpose of this activity is to preform an analysis on a variety of urine and stool samples in order to understand the procedure and purpose of these tests in the health care world.

This lesson helps students explore the functions of the kidney and its place in the urinary system. Students learn how engineers design instruments to help people when kidneys are not functioning properly or when environmental conditions change, such as kidney function in space.

In this activity, students filter different substances through a plastic window screen, different sized hardware cloth and poultry netting. Their model shows how the thickness of a filter in the kidney is imperative in deciding what will be filtered out and what will stay within the blood stream.

Students learn how crystallization and inhibition occur by examining calcium oxalate crystals with and without inhibitors that are capable of altering crystallization. Kidney stones are composed of calcium oxalate crystals, and engineers and doctors experiment with these crystals to determine how growth is affected when a potential drug is introduced. Students play the role of engineers by trying to determine which inhibitor would be the best for blocking crystallization.
