I. Conceptual Understanding
1. Name the parts of the circulatory system.
• The circulatory system consists of:
• Heart
• Blood
• Blood vessels (arteries and veins).
2. Which system is responsible for our body’s movement?
• The Skeletal System and Muscular System together support body movement.
3. What is inhalation and what is exhalation?
• Inhalation: The process of taking in oxygen-rich air into the lungs.
• Exhalation: The process of expelling carbon dioxide and water vapor from the lungs.
II. Questioning and Hypothesis
4. If you have a chance to meet a doctor (cardiologist), what type of questions would you ask about the heart?
• What is the role of the heart in the circulatory system?
• How can we keep our heart healthy?
• What causes heart diseases?
• How many times does the heart beat in a day?
• Why do athletes have slower heart rates?
III. Experiments and Field Observations
5. Place your hand on the heart and feel the heartbeat carefully. Run for some time and feel it again. Do you find any difference? Write the difference with reasons.
• Observation: The heartbeat increases after running.
• Reason: When we run, our muscles need more oxygen to produce energy. The heart beats faster to pump more oxygen-rich blood to the muscles and remove carbon dioxide efficiently.
IV. Information Skills and Projects
6. Visit a doctor or a nurse nearby and ask the functions of vital organs. Make a brief note.
• Brain: Controls all body functions and processes messages from sensory organs.
• Heart: Pumps blood, transporting oxygen and nutrients to the body.
• Lungs: Absorb oxygen and expel carbon dioxide during respiration.
• Kidneys: Filter blood and remove waste materials as urine.
• Liver: Helps in digestion and detoxifies harmful substances.
V. Drawing and Model Making
7. Draw the following on a chart. Label them and display them in the classroom:
• i) Digestive System: Include parts like mouth, oesophagus, stomach, small intestine, large intestine, rectum, and anus.
• ii) Excretory System: Include kidneys, ureters, bladder, and urethra.
VI. Appreciation
8. What amazes you in these body parts? Write down.
• The brain amazes me as it controls the entire body like a supercomputer.
• The heart pumps blood tirelessly, ensuring the survival of the body.
• The digestive system breaks down complex food into nutrients efficiently.
• The lungs provide oxygen, which is essential for energy.
• The kidneys filter impurities, keeping our blood clean.
