To reinforce students' understanding of the human digestion process, the functions of several stomach and small intestine fluids are analyzed, and the concept of simulation is introduced through a short, introductory demonstration of how these fluids work. Students learn what simulation means and how it relates to the engineering process, particularly in biomedical engineering. The teacher demo requires vinegar, baking soda, water and aspirin.

The digestive system is amazing: it takes the foods we eat and breaks them into smaller components that our body can use for energy, cell repair and growth. This lesson introduces students to the main parts of the digestive system and how they interact. In addition, students learn about some of the challenges astronauts face when trying to eat in outer space.

In this video we introduce the digestive system. We look at the two types of digestion: mechanical digestion and chemical digestion. We also look at the two subdivisions of the digestive system: the digestive tracts and the accessory structures.

The mouth is our first stop in our digestive system. It is made of our cheeks, lips, tongue, and teeth. We take a look at the mouth as well as the components and how they help with the digestion of food.

Moving down the digestive system we take a look at the throat. Specifically we examine the pharynx, and the esophagus. We also look at how we swallow, breaking it down into the two phases.

This activity was designed for blind learners, but all types of learners can use it to understand how villi function in the small intestine. The purpose of this activity is to examine a model of the inside of the small intestine to support understanding of the function of villi in digestion.

The University of Saskatchewan offers this tremendous resource that promotes the richness and diversity of the sciences, nurture curiosity and innovation, and inspire students to consider a career in science, and support teachers to provide exciting educational experiences.

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.

Students learn about the unique challenges astronauts face while eating in outer space. They explore different food choices and food packaging. Students learn about the engineering design process, and then, as NASA engineering teams, they design and build original model devices to help astronauts eat in a microgravity environment --- their own creative devices for food storage and meal preparation.

Students reinforce their knowledge of the different parts of the digestive system and explore the concept of simulation by developing a pill coating that can withstand the churning actions and acidic environment found in the stomach. Teams test the coating durability by using a clear soda to simulate stomach acid.
