=== Objectives ===
* To observe different kinds of leaves and how they differ from each other
* To explore ways of classifying leaves
* To understand the different characteristics of leaves
=== Materials Required ===
* Variety of leaves
* Sheets of paper
* Crayons/Colour pencils
* Observation sheet
=== Process ===
# Ask students to collect different types of leaves from surroundings or if there aren't many trees/plans in the school surroundings, collect a variety of leaves in advance and hand them over
# Ask students to observe the different leaves and think of ways in which they can be classified
# Probe students to think about what characteristics of the leaves they are looking at for classification and why. Ask them to share their observations
# Explain the meaning of leaf shape, margin, tip and venation which are commonly used to classify leaves
# Next, each student from one group takes 2-3 leaves, puts them under a sheet and creates an impression by colouring on the sheet with a crayon/colour pencil.
# Ask students to then record the leaf structure, shape, margins, tips and venation based on the reference sheet provided by the facilitator
# Questions to probe students' thinking:
## Why is it necessary to classify leaves?
## What do you think determines the different characteristics (size, shape, margin, etc.) of leaves?
## Can the leaf properties say anything about the plant/tree?
