Name: ___________________________ Date: ________________________
Student Exploration: Circulatory System
Vocabulary: artery, atrium, blood vessel, capillary, circulatory system, heart, platelet, pulmonary artery, pulmonary vein, red blood cell, urea, ventricle, vein, white blood cell
Prior Knowledge Questions (Do these BEFORE using the Gizmo.)
1. Why do you need blood? __Blood carries oxygenon and nutrients around you body.___________________________________________________
2. What organ pushes blood through your body? ______The heart_____________
Gizmo Warm-up
The Circulatory System Gizmo™ shows the heart and blood vessels that make up the circulatory system. Look at the heart.
1. How many chambers does the heart have? ___four_______
2. Do you see tiny “doors” that open and close as blood is pumped through the heart? __yes__ These are valves. Valves keep blood from flowing backward. 3. Turn on Show labels. What are the names of the chambers? Right atrium,
Left atrium, Left ventricle, Right ventricle
4. Observe the two parts of the heartbeat. The first part of the heartbeat is nicknamed “lub,” and the second is nicknamed “dub.” (This is because a heartbeat sounds like “lub-dub.”)
A. Which chambers contract during “lub”? _____left an right atrium
B. Which chambers contract during “dub”? ______left and right ventricle
5. Challenge: Why do you think the left atrium and left ventricle are shown on the right side of the diagram? __If you are looking the plane a human looks when he is looking away from his body it would be the left and right sides.
Activity A:
Blood flow
Get the Gizmo ready:
Turn off Show labels.
Turn on Show blood flow.
Question: How does blood flow through the heart? 1. Observe: Blood in each chamber of the heart is represented by little balls. Observe the balls as they move through the heart and lungs.
2. Label: Turn on Show labels. Label the four chambers
