About this worksheet

This 3-page 5th grade science sheet puts the heart in front of students as a line drawing with seven numbered pointer lines. They name each part from a word bank: right and left atrium, right and left ventricle, aorta, vena cava and pulmonary artery. A note at the top reminds them that left and right mean the body's left and right, so the heart's right side sits on the left of the page. Page 2 adds a coloring task and three short questions, and the last page gives the answers.

“Construct an argument that plants and animals have internal and external structures that function to support survival, growth, behavior, and reproduction.”

The three questions on page 2 tie the chambers and vessels to their jobs, including why the left ventricle wall is thickest.

What's inside this worksheet

Parts of the Heart

Students write a name from the word bank beside each of the seven numbers on the diagram. A boxed note explains why the heart's right side appears on the left of the page.

Coloring Task

Students color the side holding oxygen-poor blood blue and the side holding oxygen-rich blood red, on the page 1 diagram or a smaller one under the instructions.

Heart Questions

Three written questions ask which chamber pumps blood to the body, which vessel carries blood to the lungs, and why the left ventricle has the thickest wall.

Answers

All seven labels, the blue and red sides, and sample responses to the three questions.

How teachers use it

Before blood flow lessons

Hand it out once you have introduced the four chambers. The note about left and right catches the most common mix-up, so read it aloud before anyone writes.

Colored pencils ready

Put blue and red pencils on each desk for page 2. Ask students to say which parts go with each color before they shade.

Exit ticket

Use question 3 on page 2 as an exit ticket. A good answer links the thick wall to pumping blood all the way around the body.
