Science VIIC 21/4/21 Topic taught and Homework

Integration with Art:

Chlorophyll painting

Chlorophyll, the green pigment found in a plant’s leaves, is a key ingredient in 

the process of photosynthesis. It also makes great paint!

Material required (to be sourced by the students): 8-10 leaves , a white sheet 

of paper, a metal spoon.

Draw the outline of the bark of a tree as shown in the image below.

 Press firmly on the leaves with a metal spoon to extract the pigment and use

it to colour the leaves of the tree. Avoid plastic spoons as they break when

pressed as firmly as necessary.

 The student can also ball up few leaves and use them as paintbrush to

colour the leaves of the tree.

 Upload the photograph/scanned copy of the work if the activity is done
