Digestive System Lab

Description

Digestive System Lab Preview

SNAPs Lab Stations Activities require students to use science, math, literacy, problem-solving and engineering skills. They are designed to enhance students’ understanding of scientific concepts and help students apply scientific ideas to the real world. Each station activity promotes skills so to develop students into proficient and competent scientific thinkers.

SNAPs lab activities have five components:
• Science Skills Station to develop science skill proficiency
• Narrative Station to build science literacy
• Assessment Station to evaluate learning and understanding
• Problem-Solving Station to foster engineering design
• Synthesis Station and Project to inspire higher-order learning

Digestive System Lab Stations Activity Learning Objectives
1. Identify important structures of the digestive system.
2. Discuss the function of the digestive system and the function of digestive system organs.
3. Compare and contrast mechanical and chemical digestion.
4. Explain the process of digestion and how organs of the digestive system work together to break food down into simple nutrients that the body can use.
5. Diagnose diseases affecting the digestive system and determine treatment and outcomes for those diseases based on current medical practices.

Science Skills Station
Students will complete a demonstration of digestion (and other processes) at this station. Students will model mechanical and chemical digestion, absorption of nutrients and elimination of waste. Students will use the demonstration to better understand the function of the digestive system organs.

Narrative Station
Students will watch two videos about the function and structures of the digestive system. Students will also watch videos covering constipation (and large intestine anatomy), healthy bacteria in the gut and how your body knows you are full.

Assessment Station
Students will answer questions about key terms and ideas relating to the digestive system and digestion. Students must employ lower, mid and higher order thinking skills to answer these questions.

Problem-Solving Station
Students will diagnose diseases affecting the digestive system at this station. Students will be provided patients’ symptoms and lab results. For each patient, students will create a differential diagnosis and a final diagnosis. Students will determine the patient’s most likely treatment and prognosis based on current medical practices.

Synthesis Station
Students will compose a CER (claim-evidence-reasoning) report to summarize the lab. Students are provided the claim statement and must support the claim with observations, data and other information gathered in the lab. Students will explain how the evidence supports the claim using scientific reasoning.

Synthesis Project
Students will have a choice of 11 projects. Refer to the SNAPs Lab Stations Best Practices and Setup Guide for directions and suggestions on how to conduct the project.

NEXT GENERATION SCIENCE STANDARDS
This laboratory does not address a specific Next Generation Science Standard, but it complements NGSS concepts. It combines the three dimensions of science learning – science and engineering practices, disciplinary core ideas and crosscutting concepts – in order to meet the standard. This laboratory also makes interdisciplinary connections to STEM, Math CCSS and ELA CCSS to build the appropriate skills.
