Circulatory System - Structures and Functions of the Heart

Welcome to the introduction of the Circulatory System and today's focus on the structures and functions of the heart.

First I want you to complete the QFocus.  For this the person at the pink spot at the table group will be the recorder.  He/she will need their laptop and will record your questions into the correct Padlet below.  The student at the green spot will be the reporter for the table.  He/she will share out one or two of your questions with the group.  

QFocus: The organ of the heart is composed of many specific structures that allow for important functions within your body.

Second I want you to watch the video of the heart beating.

Task:

I want you to think about what kinds of things you witnessed in this short video.  
Why did it beat the way it did?  How many contractions does it look like it makes?
Did anything surprise you?
