    Improve Your Learning

    I. Conceptual Understanding

    1. Write a brief note on the uses of air?

    • Air is essential for breathing and survival. It carries smells, produces sound, and helps in various daily activities like flying kites, drying clothes, and drinking liquids through straws. Wind power is used to generate electricity and lift water for cultivation.

    2. Name the kind of clothes we wear in different seasons.

    1. Summer: Cotton clothes to keep cool.
    2. Winter: Woollen clothes to keep warm.
    3. Rainy Season: Raincoats and waterproof clothes to stay dry.

    3.Write differences between natural and synthetic fibres.

    1. Natural Fibres: Obtained from plants and animals (e.g., cotton, wool, silk). They are eco-friendly and breathable.
    2. Synthetic Fibres: Made artificially using chemicals (e.g., polyester, nylon). They are durable and affordable.

    II. Questioning and Hypothesis

    4. Name the reasons why people use woollen clothes in the winter season.

    Woollen clothes keep the body warm because wool traps heat and insulates against the cold. They are especially useful in cold climates.

    III. Experiments and Field-Based Observations

    5.Wash your dress with a detergent soap and write your experiences.

    Experience: Washing clothes with detergent removes dirt and stains effectively. Dark-colored clothes should not be dried in direct sunlight to prevent fading. Proper washing and drying keep clothes clean and fresh.

    IV. Information Skills and Projects

    6. Collect pieces of cloth, classify them into natural fabrics and artificial fabrics, and paste them on the chart. Display the chart.

    • Examples:
      • Natural Fabrics: Cotton, Silk, Wool
      • Artificial Fabrics: Polyester, Nylon, Rayon

    V. Drawing Pictures and Model Making

    7. Draw pictures of different types of dresses.

    Students can draw sarees, dhotis, uniforms, and casual wear like jeans and T-shirts.

    VI. Appreciation

    Say what you like at a tailor’s shop

    I like choosing the fabric for my clothes. Watching the tailor stitch the fabric into a perfect dress is fascinating. It feels exciting to see my ideas turn into reality.

    • Plants are very useful to us. They provide us with food, oxygen, medicines, timber, and fibres. Roots like carrot and beetroot are eaten as food, while flowers like jasmine and hibiscus are used for decoration and perfumes. Fruits provide us with vitamins and minerals. Plants also help in maintaining the balance of nature.

    • Water (Aquatic) Plants: Lotus, water lily, hydrilla.

    3. Identify and write some desert plants in your surroundings.

    • Cactus, barrel cactus, aloe vera.

    II. Questioning and Hypothesis

    4. What questions would you like to ask a gardener in your village to know about different types of plants?

    • What types of plants grow well in this soil?

    • How do you take care of flowering plants?

    • What are the benefits of different plants?

    • How do you grow seedless fruits?

    III. Experiments and Field Observations

    5. Go to a nearby garden or nursery. Identify and write the names of as many flowers and plants as you can.

    • Flowers: Rose, hibiscus, jasmine, marigold.

    • Plants: Tulsi, mint, neem, mango.

    IV. Information Skills and Projects

    6. Make a chart on the types of plants based on stems and hang it in your classroom.

    (This activity involves creating a visual chart showing types of stems like herbaceous, woody, or climbers with examples. Example: Banana – soft stem, Banyan – woody stem.)

    V. Drawing and Model Making

    7. Make some flowers using colour papers and decorate your classroom.

    Model Rose flower image

    (This involves crafting flowers like roses or lilies with coloured papers and arranging them in the classroom.)
