Giant Hands-On
Eyeball
Six times larger than
life, with five detachable
parts, it’s plain to see why
this giant, take-apart eye
generates such student
enthusiasm. Lucite® lens
which, your students will
discover, actually magnifies
objects and forms inverted
images. Next, they’ll
find that they can see through
the transparent, vitreous body. After they remove the
vitreous body, they’ll discover the light-sensitive retina.
Hand-numbered, the eyeball is accompanied by a twopage
study guide detailing the purpose and function
of its 19 principal features. Mounted on a tip-proof
wooden base, the unit measures 6" x 6" x 6".

Exploring the
Eye-Brain
Connection Lab
Learn that sight is as much
about perception as it is about
reality! This lab explores the
function of each part of the
eye and shows how they can
contribute to “tricking” the
brain through optical illusions.
Your students will use the
illusions and explanations provided
to experience different
types of optical illusions. Then
they’ll use what they learn to
create their own optical illusion.
Makes learning the parts
of the eye and their function
interesting and fun! Materials
for 40 students. Grades 7-10.
