Kidneys, urine formation and waste removal are the focus of this Grade 6 Science worksheet, which helps students explore how the urinary system filters blood, forms urine and removes metabolic wastes. Students also trace the path urine follows through the body and distinguish excretion from the removal of undigested food through the digestive tract.

Follow the journey from blood to urine

The reading passage introduces the kidneys as bean-shaped organs that filter blood, removing urea, excess water and some dissolved salts while allowing useful substances to return to the blood. Students learn the roles of the ureters, urinary bladder and urethra, following the route urine takes from the kidneys to its exit from the body.

A key learning point is the difference between excretion and the removal of undigested food. The resource explains that metabolic wastes are removed through excretion, while undigested material leaves the body as feces through the digestive tract. This comparison helps students connect each process to the correct materials and organs.

What students practise

The activities move from recognising urinary system structures to explaining how waste removal works. Students respond to multiple-choice questions and true-or-false statements, then use short answers to explain kidney functions, describe the route of urine and compare excretion with the removal of undigested food. A labeled-diagram task, categorization activity and short-note task provide additional opportunities to work with the topic.

The questions revisit important vocabulary and relationships, including urea, dissolved salts, urine, ureters, urinary bladder and urethra. Students are also prompted to consider how observations, models and evidence can help explain body systems. The reading passage includes a note about First Peoples knowledge, emphasising its diversity and the importance of using local First Peoples-authored or community-approved sources and crediting knowledge holders.

Included with the worksheet

• Printable student worksheet: Reading passage, multiple-choice questions, true-or-false statements, short answers, a labeled-diagram task, categorization and a short-note activity.
• Separate answer key PDF: Provides answers for checking student work.
• Student Notes lines: Space at the bottom of the worksheet for students to record notes.

Classroom use

Use this Grade 6 urinary system worksheet when introducing the kidneys and the body's waste-removal processes, or as follow-up practice after teaching body systems. The reading passage provides a starting point for the activities, while the short-answer tasks give students a chance to explain processes in their own words. The separate answer key supports checking and review, and the teacher guide offers preparation and discussion support.

Designed for Grade 6 Science: Body Systems, this resource provides focused practice with kidney function, urine formation, the urinary organs and the distinction between excretion and digestive waste removal. The resource identifies the BC curriculum framework; it does not specify an individual curriculum code.
