Source:

Collect leaves during a nature walk and create crayon rubbings. Then tap NFC-tagged leaf cards on the reader to hear facts about each plant species.

Categorisation

Props & Materials Required

  • •Fresh fallen leaves (various shapes and sizes)
  • •Thin white paper or tracing paper
  • •Wax crayons (peeled)
  • •Magnifying glass

Step-by-Step Instructions

1

Nature Walk Collection

Collect fallen leaves from the garden. Observe differences in size, edge shape, and smell.

2

Magnifier + Crayon Rubbing

Use a magnifying glass to inspect veins, then do crayon rubbings to capture the patterns.

3

Scan the Leaf Card

Match the rubbing to an NFC-tagged plant card and tap it. Speaker says: 'This is a NEEM leaf! Neem is a medicinal tree. Its leaves keep insects away!'

4

Classification Challenge

Sort leaf cards into 3 NFC reader zones labeled 'Tree', 'Bush', 'Herb'. Correct placement — green LED! Wrong — speaker hints: 'Tulsi is an herb, not a tree!'

Why It Works & Notes

Crayon rubbings highlight leaf vein structures. NFC-triggered audio facts create lasting botanical associations — children remember 'Neem leaves are used as medicine!' long after the activity.
