Indiana Academic Standards for Science (2023) · Absorption and Excretion, the Urinary System

Teacher's field guide

What Students Need to Do: Students locate the kidneys, ureters, bladder, and urethra on a body diagram. They explain how each organ helps make, move, store, or release urine.
What Mastery Looks Like: A student labels all four organs and traces urine from the kidneys out of the body. They explain that the kidneys filter blood and adjust how much water leaves in urine.
Common Misconceptions: Students may think the bladder makes urine, rather than stores it. They may mix up the ureters, which carry urine to the bladder, with the urethra, which carries it out of the body.
How to Assess It: Give students an unlabeled urinary system diagram. Ask them to label the four organs, draw arrows showing urine's path, and write each organ's job.

Lesson moves

Have pairs place paper cutouts of the kidneys, ureters, bladder, and urethra on a torso outline, then draw arrows between them.
Ask students to write what would happen to urine flow if one ureter were blocked.
Play a card match: students pair each organ name with its location and job, then check against a diagram.
After discussing exercise and water loss, ask students why urine may look darker when someone has not had enough water.
