This activity is a quick
way to demonstrate how blood is pumped through the blood vessels.
Do it with our Circulation Outline activity, and then add it to
your hand project from our workbook, About Me:
||All you need is
a straw and a red pipe cleaner. A clear straw is preferred (found
on amazon) because blood vessels are translucent, but you can
also use a pink straw.
your child a picture of a heart. Tell him that it's about the
size of his fist.
with your child that your fists are hearts that are pumping.
Practice squeezing your fists while mimicking the heartbeat
rhythm, pa-pum pa-pum pa-pum.
|Now have your child
hold the end of the pipe cleaner with his heart-fist and push
it through the blood vessel (straw) while pumping. If possible,
have him push only when he pumps. This takes some coordination,
so he might need assistance.
Why We Like It:
This activity teaches:
1. The size of the heart
and what it looks like
2. How the heart
3. Blood vessels are tubes
4. Blood does not continuously flow through the vessels, but moves
with the beat of the heart Kids enjoy "threading" the pipe cleaner
through a straw (a fine motor skill) and watching as the straw turns
from clear to red.
Extend the Activity:
Make 5 of these vessels filled with blood and add them to your hand
project from Lesson 9 in our workbook, About Me.
