Question

Turn a nature walk into a research project.

1. Observe different leaves and study their adaptations for various environments, such as desert, very moist or aquatic habitats.
2. Consult an elder community resource person about their knowledge on different plant leaves, such as leaves that remain fresh for a long time, repel water or deter insects. Find out their traditional uses, such as making plates, preparing cooling wraps or functioning as insect repellents

Answer 1

1. Observe different leaves and their adaptations
   • Desert plants (e.g., cactus, aloe vera): Leaves are small, thick, or modified into spines to reduce water loss and store water.
   • Plants in very moist areas (e.g., banana, colocasia): Leaves are broad and large to capture more sunlight. Some have drip tips that help rainwater flow off quickly.
   • Aquatic plants (e.g., lotus, water lily): Leaves are broad and flat so they can float on water. They have a waxy surface that repels water, and stomata are usually on the upper surface.
2. Information from an elder/community resource person
   1. Banana leaves: Stay fresh for a long time and are traditionally used as eco-friendly plates for serving food.
   2. Lotus leaves: Their waxy surface repels water and keeps them clean (self-cleaning effect).
   3. Neem leaves: Have a strong smell that repels insects. They are placed with stored grains and clothes to protect them from pests.
   4. Tulsi (Holy Basil) leaves: Traditionally used in home remedies for coughs and colds, and are believed to help keep insects away.
   5. Aloe vera leaves: Their cooling gel is applied to burns, cuts, and skin irritation.

Different plants have leaves specially adapted to their environments. These leaves are also valuable in daily life for serving food, traditional medicine, cooling, and protecting against insects.
