Excretory System Teacher Resources
Find Excretory System educational ideas and activities
Learners investigate how kidneys function. They discuss how a dialysis machine works, and conduct an experiment in which they filter different substances through a plastic window screen, various sizes of hardware cloth, and poultry netting to analyze how the excretory system functions.
Students examine the functions of the kidney and its place in the urinary system. They discuss how astronauts go the bathroom in space, examine labeled diagrams of the urinary system, and draw a large scale drawing of the excretory system with chalk outside and walk through the drawing and explain how the different parts work.
Students discuss what happens to the trash in their home. They talk about what would happen if they didn't remove the trash. Students relate their home trash to the excretory system of their bodies. They label a diagram of the urinary system. Students model kidney function by creating a filtering system with gravel and a screen.
This interesting, 17-page series of lessons was written by two second grade teachers who attempted to write a full year's worth of curriculum for their classes. What is presented here is an excerpt from that full-year plan. These lessons focus on making books, writing tall tales and folk tales, exploring Asian cultures through language lessons, writing poems, and perfoming in plays. Some outstanding ideas!
