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.

1. Give some examples of animals that have thick fur on their skin.
Examples: Sheep, Polar Bear, Yak, and Alpaca.
2.Why is a hen called oviparous?
A hen is called oviparous because it lays eggs, and its young ones hatch from these eggs.
3. Sarath says that the duck and the crocodile belong to the same group. Do you agree, why or why not?
Yes, they both belong to the group of oviparous animals because they lay eggs. However, they are different in habitat and lifestyle. Ducks are birds, and crocodiles are reptiles.
II. Questioning and Hypothesis
4. What will happen if there are no crows?
If there are no crows, the natural ecosystem will be disrupted. Crows help clean the environment by feeding on waste and dead organisms. Without them, waste accumulation might increase, leading to a polluted environment.
