Modeling Kidney Function Lab
Investigation
Model the action of a kidney for a striking visual demonstration.
Students construct a model of a kidney using
a semi-permeable membrane to filter a completely safe
solution which simulates blood. The simulated blood
contains “cells” which cannot cross the semipermeable
membrane, remaining in the kidney model. The resulting
filtrate resembles urine, which students test for salt and
other waste products. The simulated blood cells can also
be seen and counted under a microscope just like real
blood! Students will: investigate the function of a human
kidney by constructing a model, understand the mechanism
of urine formation in the kidney, observe osmosis
as it relates to kidney filtration, and relate kidney function
to homeostasis. For 40 students. Middle school and
up. Sh. wt. 1.47 kgs.

Life/form ® Human
Reproduction and
Development Kit
There’s no better way to depict the actual
size and developmental stages of a fetus
than with these incredibly realistic replicas!
A thorough multimedia program, this
kit presents an in-depth look at embryo
and fetus development in humans. The
accompanying text and teaching guide
provide background information and study
questions and include transparencies and
blackline masters. The videotape titled, The
Miracle of Life, along with the transparencies,
tells the fascinating story of embryonic and
fetal growth. The blackline masters highlight
important study points for students. The
dramatic Life/form ®
reproductions show the
stages of human development in a unique,
innovative way — plastic models and replicas each student can examine and study. The kit offers a direct and complete
approach to an understanding of human reproduction from fertilization to birth. Nasco’s total teaching program offers
nine realistic Life/form ®
reproductions, four models of the early stages of the embryo, five actual replicas of the growing
fetus, PLUS…
