The Heart House: Science Model

and function of the human heart, perfect for introducing the circulatory system to younger students (Grades K-4) or as a fun, memorable review for older elementary grades.

This resource uses easy-to-understand analogies like a “House,” “Rooms,” “Doors,” and a “Battery” to make the science of the heart concrete and fun!

Key Features & Content:

Size and Strength: Compares the heart’s size to a fist and describes it as a strong, muscular pump.

Specialized Muscle: Identifies the heart as being made of cardiac muscle that works continuously.

The Heart House: Details the three main layers (Pericardium, Myocardium, Endocardium) using simple analogies like a raincoat and a smooth lining.

The Four Rooms (Chambers): Clearly labels and describes the function of the four chambers (Left/Right Atrium and Ventricle) as upper welcoming rooms and lower strong pushing rooms.

One-Way Doors (Valves): Explains that valves act as one-way doors to keep blood flowing forward, making the “FLUB-DUB” sound.

The Heart’s Battery: Explains that the heart has its own battery and wires (the pacemaker/SA node) that send the signal to squeeze.

Activity Idea: Includes an activity to “Make a Fist” to visualize the heart’s size and practice the “LUB-dub” rhythm.

Ultimate Summary: A final page summarizing the heart as a “strong muscle, smart one-way doors, and electrical spark”.

Perfect for: Health classes, science centers, interactive notebooks, and whole-class instruction on the human body.
