Body Systems Working Together
Major human body systems include the skeletal and muscular
systems, the circulatory and respiratory systems, the digestive
and excretory systems, and the nervous system. These
systems all have different jobs and abilities, but work together
with one objective — a healthy human body!
4. As the leader, you will be giving instructions to the group of
volunteers to help them accomplish the goal of moving the
bucket of water from person #1 to person #5. When your
group is ready, you can begin.
Conclusions
• Which human body system was the leader of the group most
like? Explain.
Objective
Create a living representation of how body systems work
together.
Materials
— 5 blindfolds
— a small plastic bucket full of water
— chalk
— a ruler
— a tray
— 5 volunteers to help
— an open area to work
• What was the most challenging aspect of completing this
investigation?
Safety Notice: All applicable laboratory safety rules must be followed. Students should
not perform any experimental activity without the teacher’s supervision and express
permission. Students must follow safety guidelines and wear appropriate protective gear.
Procedure
1. Have your five volunteers spread out but stand close
enough so that their fingers touch.
• In what ways did the volunteers rely on the leader? In what
ways did the leader rely on the volunteers? In what ways did
the volunteers rely on each other?
2. Use chalk to draw circles around the feet of each volunteer
to mark their position. Your volunteers may want to stretch
to get nice and loose. They’ll be doing some physical work!
3. Each volunteer will represent a body system. The challenge
is for all the systems to work together to get a job done —
just as the systems of the body work together to keep us
healthy. In this case, a small bucket of water must be moved
from person to person — first kid to the last — without
spilling a drop. However, each system will have special
abilities and limitations, like the systems of the human body
do:
a. The first person’s feet must remain planted and can
only use his/her hands.
b. The second person’s feet can move within the circle
but cannot use his/her hands.
c. The third person must keep a tray in both hands at
all times.
d. The fourth person’s hands can be used but must stay
behind his/her back.
e. The last person in line has to use a ruler instead of
his/her hands.
f. All five volunteers must wear blindfolds and cannot talk.
g. You will be the leader. You will be the only one who
can see, move around freely and talk.
