Homemade Stethoscope

We've been enjoying studying the human body this year.  We're loosely following Guest Hollow's Curriculum.  One of the fun kits we ordered was the Magic Schoolbus - Journey Into the Human Body.  Today we built our own stethoscope using some tubing, a funnel and a balloon.  The amazing thing is that it really worked!  I could not believe how loudly and clearly we could hear the heart beat. Then the kids jumped up and down for awhile to get their heart racing and listened to it slowly get back to a resting pace.  We're really enjoying this kit.

Reading the directions...

Putting the balloon on the funnel...

It works!

Final Product...our homemade stethoscope..

Looks like a great activity. Budding doctors in the house?
