Teacher's field guide

What Students Need to Do: Students make a model that links a cardiac muscle cell to cardiac muscle tissue, the heart, the circulatory system, and a person. They use arrows to show how these parts work together to move blood.
What Mastery Looks Like: A student puts the levels in order and explains how contracting muscle cells help the heart pump blood through vessels. Their model shows that the heart contains other tissues too, and that the circulatory system includes more than the heart.
Common Misconceptions: Students may confuse tissue with an organ or place organs inside cells. Some draw the circulatory system as just a heart, or think the heart is made only of muscle tissue.
How to Assess It: On an exit ticket, have students arrange these terms in a labeled diagram: human, heart, cardiac muscle tissue, circulatory system, cardiac muscle cell. Ask them to add one sentence explaining how contraction helps move blood.

Lesson moves

Give pairs five nested paper cups to label from cardiac muscle cell to person, then have them write each level’s job on its cup.
Ask students to write: Why can the heart pump blood when a single cardiac muscle cell cannot?
Play a card-sort relay: teams order five shuffled heart-related cards by level and explain each choice.
Have students count their pulse before and after marching in place, then mark on a body diagram the parts that move blood faster.
