    Chapter 4: Know Our Organ Systems | Class 5 | EVS | AP SCERT

    Andhra Pradesh

    Based on Chapter 4, “Know our organ systems” from the Class 5 EVS textbook, here are the answers to the “Improve Your Learning” section.

    Improve Your Learning

    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.

    Climate Change | Class 5 | EVS | Chapter 2 | AP SCERT Textbook Solutions

    Here are the answers to the “Improve Your Learning” section for the lesson “Climate Change”

    I. Conceptual Understanding

    1. What is climate?

    • Climate refers to the weather conditions such as temperature and rainfall prevailing in an area over a long period.

    2. What are the effects we face due to climate change?

    • The effects of climate change include untimely rainfall, droughts, floods, melting of ice, rising sea levels, cyclones, tsunamis, and forest fires. It also impacts food production and causes the death of aquatic plants and animals.

    3. What are the reasons for climate change?

    • The main reasons for climate change are deforestation, pollution from industries and vehicles, overuse of natural resources, burning waste, and the excessive use of plastic and harmful chemicals.

    II. Questioning and Hypothesis

    4. In your village, people are suffering from drought. Can you guess the reasons?

    • Drought could be due to a lack of rainfall caused by deforestation, climate change, overuse of groundwater, pollution, and improper agricultural practices.

    III. Experiments and Field Observations

    5. Observe the process used for disposing of garbage at your home and make a report.

    • At home, garbage is segregated into wet waste (food leftovers, peels) and dry waste (plastic, paper). Wet waste is composted to make manure, while dry waste is sent for recycling or discarded. However, in some cases, improper disposal, such as burning or dumping, causes pollution.

    IV. Information Skills and Projects

    6. Collect information about students who are using steel water bottles instead of plastic water bottles.

    • A survey at school shows that 60% of students use plastic bottles, while 40% have switched to steel bottles. The latter group prefers steel bottles for their durability, safety, and eco-friendliness, reducing plastic pollution.

    V. Drawing and Model Making

    7. Make a pen stand, flower vase, etc., by using a plastic water bottle.

    • This activity involves cutting and decorating plastic bottles creatively to reuse them as pen stands, vases, or storage containers, promoting recycling.

    VI. Appreciation

    8. Prepare some slogans on ‘Save Environment.’

    • “Plant Trees, Save Lives.”

    • “Reduce, Reuse, Recycle.”

    • “Say No to Plastic, Yes to Nature.”

    • “Save Water, Save the Planet.”

    • “Act Now, Save Tomorrow.”
