Breathe In, Breathe Out... (Respiratory System Activities)

After studying the

Nervous System

and the

Circulatory System,

we continued our journey through the human body

by heading to the

Respiratory System.

We began by viewing...

...the "Once Upon a Time..."

videos about breathing.

Part 1

Part 2

Part 3

(I love the visual notes Baby Girl created

while we watched the videos!)

On another day during our study about

the Respiratory System,

we completed the

Breathe In, Breathe Out

activity found in our

From Head to Toe 

AIMS Science Book.

We created a model of the lungs

using a few simple materials

from around the house...

*2 liter bottle

(cleaned out and label removed)

*Duct tape

*2 balloons

*2 bendable straws

*Modeling clay

1.  Take the straws and bend the ends of them

at an angle.

2.  Stretch out the balloons.

3.  Attach the balloons to the ends of the straws

with duct tape.

4.  Place the straws back to back

to form a "Y" shape.

5.  Tape the straws together.

6.  Place a good sized ball of clay towards the

straight ends of the straws,

leaving the the holes open.

7.  Carefully place the straws into the bottle

and secure the clay around the opening of the bottle.

Then give the model a test drive...

We tried our model out a couple of different ways.

First the kiddos blew into the straws...

...and then they squeezed the outside of the bottle.

Totally-cool.

Finally,

we recreated a visual image of the lungs

following the instructions and printables from

Relentlessly Fun Deceptively Educational.

What a breath of fresh air these activities were!
