How does the urinary system work with the digestive system

Content Statements

This unit shows how the digestive system breaks down ingested food into particles small enough to be absorbed into the blood and use this food to produce cellular energy.

Overarching Essential Question

What do the digestive and urinary systems do with the food taken into the body and how is that food converted into energy and waste removed from the body?

Overarching Enduring Understandings

The digestive system  breaks down our food into usable particles that the body can use and convert into energy and together with the urinary system the waste is eliminated

Unit Essential Questions

What are the structures and functions of the alimentary canal, and accessory digestive organs?

What is the structure and function of a kidney?

How do enzymes work in digestion?

What is the structure and function of the bladder?

Unit Enduring Understandings

The digestive and urinary systems work to breakdown and metabolize food and eliminate waste from our bodies.

Unit Rationale

To understand the workings of the human body we have to understand the digestive and urinary systems.

Unit Overview

In this unit students will explore the workings of the urinary and digestive systems using teeth identification to start the digestive system lab and a kidney dissection for as the major organ of the urinary system. 

Authentic Learning Experiences

Cat dissection

21st Century Skills and Themes

Collaboration

Students work cooperatively to conduct labs.

Oral Communication

Students use science vocabulary in discussion. Students will discuss lab results when writing lab conclusions.

Critical Thinking

Making predictions and formulating hypothesis and interpreting data from lab and data given by teacher.

Written Communication

Students write their predictions, observations and/or interpretations using science vocabulary.

Technology

Students use the internet to research, and view different cells, to investigate current events.

Unit Learning Targets/Scaffolding to CPIs

Students will use what they already know about the scientific method and lab reports to write complete and detailed lab reports.

Students will use what they know about ATP to understand digestion and breaking down food to get energy.

Key Terms

Mastication - chewing

Nephron - the structural and functional units of the kidneys

Pyloric sphincter - connects the stomach to the intestine

Small intestine - the body’s major digestive organ

Ureters - two slender tubes that bring urine to the bladder

Urethra - a thin walled tube that takes waste from the bladder to the outside

Urine - nitrogenous wastes and unneeded substances from the body

Customizing Learning/ Differentiation

Special Needs

Students are engaged in small group work, where students of differing abilities and learning styles should be grouped together.  Students act as peer coaches to support students with special needs.

ELL

The student will share their own perspective or cultural ties to their studies.  Students will improve their English using magazine and newspaper articles for weekly current event summaries.

Gifted Learners

Supplement studies with current event biology articles.

Mainstream Learners

Throughout the unit during class time, plan and hold small learning sessions/work groups where students can selectively attend to learn more about specific topics.  Hold these sessions often, changing the topics, using maps, making models, interpreting data, graphs and charts.
