WATER
A. Ocean Current—
Demonstration Model
Visually demonstrate the effects of temperature and
salinity on the circulation of water with cold blue and
hot red water and a saltwater concentration gradient.
AP7313—$33.55
B. Salinity of Water—Student
Laboratory Kit
Analyze sodium chloride in saltwater with a microtitration
of saline with silver nitrate and a fluorescein
indicator to understand how salinity affects water
availability and shortages.
FB1878—$77.55
C. How Hard Is Your Water?
Student Laboratory Kit
Test and measure the level of hardness in your local
water supply by analyzing its calcium and magnesium
salt residues. As the compounds become more
numerous, the “hardness” of the water rises.
FB0411—$21.45
D. Water Cycle Model with
Study Cards
Simulate the water cycle as it occurs in nature with
this two-piece plastic terrain model to study clouds,
fog, rain formation, rivers and melting snow processes
firsthand. Ten color study cards are included.
16" L x 12" W x 2½" D.
AB1159—$117.90
Deluxe Stream Table
This floor-model stream table lets students observe
erosion caused by running streams and waterfalls, see
the growth of deltas, create different drainage patterns
and more with two independent streams.
AP5126—$1,688.95
