SCIENCE WORKSHEETS ON CIRCULATORY SYSTEM
Your 11-year-old just stared blankly at a diagram of the human heart and asked i...
Heart Anatomy Diagram Worksheet
A labeled diagram of the human heart showing chambers, valves, and major blood vessels. Students color-code oxygenated and deoxygenated blood flow, then answer questions about the heart's pumping action and circulation pathway.
Blood Flow Path Labeling Activity
Trace the journey of a red blood cell from the lungs to the toes and back. This worksheet includes arrows and blank spaces for students to fill in key structures like the aorta, vena cava, and capillaries.
Circulatory System Vocabulary Match
Match terms like artery, vein, capillary, and plasma to their correct definitions. A fun cut-and-paste or draw-a-line activity that reinforces key vocabulary for upper elementary or middle school science classes.
Heart Rate Experiment Recording Sheet
Students measure their pulse before and after exercise, recording data in a table. They then graph their heart rate changes and write a short conclusion about how physical activity affects circulation.
Blood Components Pie Chart Worksheet
A blank pie chart representing the composition of blood—plasma, red cells, white cells, and platelets. Students calculate percentages and label each section, with a short reading passage explaining each component's function.
Circulatory System Crossword Puzzle
A 15-clue crossword covering major terms: aorta, atrium, ventricle, hemoglobin, and more. Perfect for review or homework, this worksheet challenges students to recall definitions and spellings in a fun format.
Oxygen Exchange in Capillaries Diagram
A detailed illustration showing how oxygen and carbon dioxide diffuse between capillaries and body cells. Students label arrows and write a paragraph explaining the exchange process using provided word banks.
Healthy Heart Habits Checklist
A practical worksheet where students check off heart-healthy habits like eating vegetables, exercising, and avoiding smoking. They then write a short pledge describing one change they will make to improve their circulatory health.
Circulatory vs. Respiratory System Venn Diagram
Compare and contrast the circulatory and respiratory systems using a two-circle Venn diagram. Students list unique functions and shared roles, such as transporting oxygen and removing carbon dioxide from the body.
Blood Vessel Types Comparison Table
Fill in a table comparing arteries, veins, and capillaries by structure, function, and wall thickness. Includes a small diagram for each vessel type and a follow-up question about why veins have valves.
Heart Anatomy Diagram for Students
A labeled cross-section of the human heart shows chambers, valves, and major blood vessels. This science worksheet helps students identify parts like the aorta, ventricles, and atria while learning blood flow direction.
Blood Flow Path Activity Sheet
This worksheet traces oxygen-rich and oxygen-poor blood through the circulatory system. Arrows guide students from the heart to lungs and body, reinforcing how arteries, veins, and capillaries work together.
Circulatory System Vocabulary Match
Students match key terms like plasma, platelets, and pulse to their definitions. This worksheet builds science vocabulary while explaining how blood transports nutrients, oxygen, and waste throughout the body.
Healthy Heart Experiment Worksheet
A hands-on activity where students measure their pulse before and after exercise. The worksheet prompts them to record data, graph heart rate changes, and understand how physical activity strengthens the circulatory system.
