Turn a Plastic Bag into an Inflatable Heart

Materials Required:
Red plastic bag
Pipe cleaners (for veins and arteries)
Plastic straws
Tape or glue
Scissors
Steps Involved:
Color the plastic bag red and cut it into a heart shape.
Attach pipe cleaners to the plastic bag to represent veins and arteries.
Insert plastic straws into the edges of the bag, securing them with tape or glue.
Inflate the bag by blowing into the straws to simulate the heart “beating.”
Discuss how the heart pumps blood through the veins and arteries, and how this model represents that process.
