Skeletal Unit Test
Case Study
There is a volunteer
neighborhood
cleanup day in your
community. A young
boy who is helping
out by dragging a
heavy bag of litter all
of a sudden lets out a
loud cry of pain.
You are thinking that
maybe the boy
pulled a muscle.
To your surprise,
you notice that his
hand is dangling as
if he broke his
forearm.
You rush the child to
his parents, and he
his hurried off to the
hospital. Later that
day, you see the boy’s
father and he tells
you how the boy is
doing. He laments
that his son should
really be more
careful about his
activities…
His son has broken
both is legs twice,
as well as that
same arm, on the
padded school
playground. He
then explains that
it takes a long time
for the boy’s bones
to heal.
The father mentions that
two years ago the boy
lost his hearing in one
ear after getting too
close to an exploding
fire cracker. The father
ends the story saying,
“Otherwise, he is your
typical kid. He hardly
has a sick day off from
school and he is growing
like a weed.”
Directions…
• Do not start googling like a madperson!
• Use your knowledge of bones and growing to
figure out what is going on here.
• Why is this boy so accident-prone?
• How is it that his bones break so easily?
• How might his hearing loss be related to
bones?
• Email me your answers! You will earn points based
on the rationale of your hypothesis, you don’t have to get
an exact diagnosis!
