Let use try:
to identify what type of leaves we have picked out.
What differences do you see between the leaves you have.
What are something similar you can identify between the leaves.
Try to identify the parts of a leaf.
Make small diagrams of your leaf ( no shading, if you want to shade use dots or * crosses (*).
Also make sure to make a title underneath the drawing which can start with for example:
Drawing showing a leaf of a sea grape tree.
Explore: lets view different leaves

Apex: point part of the leaf ( not in all types of leaf) helps in dripping excess water during rainfall.
Lamina/blade: helps in absorbing sunlight
Margin: gives the shape of the leaf (wavy, serrated, entire)
Mid rib: vein that runs in the middle
Petiole: short stem attaches leaf to stem.
Vein: transport water and food.

Photosynthesis Sunlight
Carbon dioxide + water Food + oxygen
Chlorophyll
The process of where plants use the carbondioxideexcreted by animals combined with water in side the chlorophyll and with the help of the suns energy it makes food (glucose) and excretes oxygen.
