====Summary====                   
{{$demo.summary}}



====Procedure====  
  -Take a nature walk around your school, garden, or local park to collect a variety of leaves from different trees and bushes.  
  -Bring the collected leaves back to your workspace and lay them out flat on a clean surface.  
  -Record observations for each leaf, noting details such as color, size, shape, edge (smooth, toothed, jagged), and vein pattern (parallel, branched, net-like).  
  -Sort the leaves into groups based on one attribute at a time:  
     *By size: small, medium, large  
     *By shape: oval, heart-shaped, needle-like, lobed  
     *By edge: smooth, toothed, wavy  
     *By color: shades of green, red, yellow, brown  
     *By vein structure: parallel, pinnate, or palmate patterns  
  -Once sorted, discuss how and why each group was formed and what traits were used.  
  -Create **leaf rubbings** by placing a leaf under a sheet of paper and gently rubbing a crayon or pencil over it to show its texture and vein pattern.  
  -Optional: Glue the leaves or rubbings into a “Leaf Journal” or make a display chart showing classification criteria.

====Variations====
  *Introduce scientific classification terms like “deciduous” and “coniferous.”  
  *Use printed leaf identification cards or field guides to identify tree species.  
  *Include measurements (length, width) and make graphs comparing leaf sizes.  
  *Use digital photos to create an online classification gallery.


====Safety Precautions====
  *Do not collect leaves from poisonous plants.  
  *Wash hands after collecting and handling leaves.  
  *Use blunt scissors or safety cutters if trimming leaves.  
  *Ensure students stay on designated paths and avoid climbing trees




====Questions to Consider====
  *Which characteristics were most useful for grouping leaves? (Shape and edge type often show clear differences.)  
  *Did you notice any patterns among leaves from the same area or tree type?  
  *How does leaf structure relate to a plant’s environment? (For example, needle-shaped leaves conserve water in dry climates.)  
  *Why do scientists classify plants and animals? (To organize living things and better understand relationships between species.)  
  *What challenges did you face when classifying your leaves? (Some features overlap, showing the need for consistent criteria.)
