Human Body Systems Part 5 Digestive System Unit

Digestive System Unit Overview:

This unit includes 6 lessons (50 minutes each) with a 15-page printable work bundle. Students explore the digestive system through interactive activities, simulations, quizzes, and engaging visuals. The lessons follow a detailed, editable PowerPoint slideshow, which can be converted for Google Classroom. Comprehensive answer keys, materials lists, video links, crosswords, and assessments are included to streamline your teaching experience.

Key Features:

• Work Bundles: Students fill in critical notes, conduct activities, and answer questions, aligning seamlessly with the PowerPoint slideshows.

• Hands-On Activities: Includes a digestive system simulation, food breakdown experiments, and taste-related activities.

• Interactive Content: Features games, built-in quizzes, and hidden box challenges for active learning.

• Editable Resources: Easily customize slides and materials to fit your classroom needs.

Topics Covered:

• Nutrients and energy for living organisms.

• The process of chemical and mechanical digestion.

• Key digestive organs: stomach, liver, gall bladder, pancreas, small intestine, large intestine.

• The swallowing reflex, peristalsis, and the role of mucous.

• Form Follows Function in the digestive system.

• Activities demonstrating digestion time, nutrient absorption, and food breakdown.

Lesson Highlights:

Introduction to Digestion and Nutrients:

• Begin with a discussion on breakfast foods and nutrients.

• Explore the essential nutrients needed for life using visuals and student-led Q&A.

• Introduce chemical digestion with an activity involving chewing bread to observe enzymatic changes.

Taste and Mechanical Digestion:

• Conduct a taste activity with Sour Patch Kids, cocoa powder, and saltwater to explore taste buds.

• Demonstrate mechanical digestion with a hands-on activity using graham crackers, bananas, and water to simulate food breakdown.

The Digestive Process:

• Introduce the swallowing reflex and peristalsis through a golf ball simulation.

• Discuss the stomach’s role in digestion and experiment with baking soda and vinegar to mimic stomach acid reactions.

• Highlight the duodenum, liver, gall bladder, and their roles in digestion.

Small and Large Intestines:

• Show how villi in the small intestine aid in nutrient absorption (Form Follows Function).

• Use a tic-tac-toe activity to reinforce understanding of digestion and nutrient breakdown.

• Describe the large intestine’s function in water absorption and waste formation.

Digestive System Simulation:

• Students work in groups to simulate the digestive process, including mechanical and chemical breakdowns of food in small bags.

• Each group performs tasks representing different parts of the digestive system.

Review and Assessment:

• A 20-question review game wraps up the unit, with bonus questions for added fun.

• Hidden box challenges reinforce visual learning by revealing digestive system images step by step.

Additional Activities:

• Peristalsis Demonstration: Students mimic the movement of food through the esophagus.

• GI Tract Activity: Use a wacky noodle and garden hose to demonstrate the length of the gastrointestinal tract.

• Interactive Digestive System Assembly: Students work together to build the digestive system in the correct sequence.

Engaging and highly interactive, this unit combines science with hands-on exploration and games to ensure students fully understand the digestive system. The lessons are packed with visuals, simulations, and activities to make learning fun and memorable.
