Modeling Convection Currents
Small groups of students can use unique Lab-Aids®/
SEPUP materials to investigate convection currents
in water and develop an operational understanding
of the relationship between
water temperature
and its movement.
This knowledge can
then be applied to
geology as students
analyze data about the
earth’s layers and convection
currents in the
lithosphere. The information
gathered from
these experiments is
then combined
to explain the
motion of the
earth’s tectonic
plates.
Grades 6—12.

Force-Motion Wheel
Students will investigate various earth and space events with experiments that include
observing and recording force and motion concepts related to gravity, magnetism, Coriolis
effect, polar constellation movement, and earth’s heat transfer cycles. The hands-on activities
may be completed on a desk, table, and/or classroom overhead projector. Includes
acrylic Plexiglas ® wheel (8-1⁄2" dia.), super magnets, launch clip, steel balls, bumper pads,
pivot caps, adhesive gum, clear tubing and connectors, and teacher guide. Grade 9 and up.

Earth Science
Weather
Current Flow Activity Model
Demonstrate the effects of density on current flow! Differences in density — caused
by variations in temperature and salinity — determine our ocean’s currents. Using this
durable, clear, acrylic model, your students will simulate the movement of warm and
cold water between polar and equatorial regions. They’ll also model the current movement
which results from density gradients. In the process, students will learn about
convection currents, weather fronts, and how ocean currents affect our climate. Model
includes segmented compartments which allows separation of water of different densities.
Includes comprehensive teacher and student guides with a variety of activities.
18" L x 3" W x 8" H. Middle school and up. Sh. wt. 3.91 kgs.
SB37371M — $303.40
Coriolis Effect Kit
As the steel spheres track a pattern on the kit’s
turntable, students simulate the effect of the
earth’s rotation on winds, ocean, currents, and
material objects. Each kit includes one 14" dia.
base with erasable tracing surface mounted on
a turntable, removable launch structure, two 5 /8"
dia. steel spheres, and teacher’s guide. Grades
6—12. Sh. wt. 0.59 kgs.
SB28782M — $51.15
Ocean Activity Model
Large, easy-to-use model gives your class a
firsthand look at ocean circulation patterns.
Simply place cold, blue-coloured water in one
cylinder and hot, red-coloured water in the
other to watch density currents in action. Your
students can also substitute saltwater and
freshwater to observe their effect on circulation.
Made of durable plastic for years of use. Includes
detailed teacher’s guide. Size: ¼" L x 4½" W x 12"
H. Grades 5—12.
Sh. wt. 1.27 kgs.
SB31280M — $118.95
Water Cycle Model Activity Set
This three-dimensional demonstrator creates a water cycle as it occurs in nature. A fascinating,
ingenious experimental model that actually causes the rain to fall, then evaporate
in a continuous cycle. It also graphically shows distillation of water as it changes to gas.
Students can examine the evaporation and condensation process within the plastic
model. Study cards encourage hands-on learning. Teacher developed activity notebook
also includes a full-colour overhead transparency and basic understandings to support
classroom activity. Grades 5—12. Sh. wt. 1.36 kgs.
SB25175M — $118.95
Water Cycle Model Only. Sh. wt. 0.99 kgs.
SA09171M — $107.05
Accent Water Cycle Kit
You don’t need expensive equipment
to study water cycles in your
classroom! With these few materials,
plus salt water, crayons, a can of cold
soda pop, you can study evaporation
and condensation, humidity and the
dew point, deposition and sublimation
— all with hands-on activities.
Teacher developed instructions feature
background material, detailed
procedures, challenge questions,
journal pages, and answers to all
posed questions. Three distinct lesson
plans could encompass a week’s
instruction! Kit includes lesson plans,
20 thermometers, 8 aluminum cans,
20 plastic containers, sponge, tablespoon,
and 10 plastic spoons. For up
to 30 students working in groups of
three. Grades 6—12.
Sh. wt. 7.63 lbs.
