Objective: Understanding the different cycles that exist in nature and in our daily lives that govern the ways the biosphere functions.

Age group : 6-12

Lesson 1:

  1. Observe the following life cycles  in a pond.Draw and label.
  2. Life cycle of a frog
  3. Life cycle of a dragonfly
  4. Compare what is drawn and what is in the picture and learn the keywords.

Lesson 2:

Lifecycle of a butterfly :

  1. Draw the lifecycle of a butterfly.
  2. Observe and name a plant/shrubs/trees that attract lots of butterflies . Eg :Singapore cherry
  3. Observe and name a plant/shrub/tree that has caterpillars(erukkam plant) .
  4. Observe and name a plant where you find eggs of a butterfly (Neem tree).

Note : Butterflies, bees and wasps play an important role in pollination. Draw the lifecycle of a flowering plant.

Lesson 3 :

Lifecycle of a flowering plant:

Nitrogen cycle.png

Nitrogen Cycle :

  1. In this cycle, observe the nitrogen fixation by plants.
  2. Name some plants that fix nitrogen in the soil.
  3. Interview an organic farmer and find out what are the crops that fix nitrogen and how do they alternate crops.
  4. In your body, find out how nitrogen is used for body functions eg: protein synthesis.
  5. Look at the labels of different products that you eat .Write down the names of the compounds that contain nitrogen.

Lesson 9:

The cycle of Producer, Consumer and Decomposer:

  1. Write a paragraph about decomposers using the following keywords: dead decaying matter, moisture, nutrients , soil , breaking down .
  2. Write a paragraph on the role of fungal network for the growth of trees.

Lesson 10:

Rock cycle.png

Rock Cycle:

  1. Find names of rocks that are found In your locality.
  2. Write down the different forms of weathering.(Eg In Tiruvannamalai hill which is made of granite rock , often we see peeling happening due to heat and cracks form through which water penetrates and the gap increases eventually breaking the rocks. Roots of fig trees penetrate through smaller rocks. On of the teachers observed how a Pachai kiluvai tree had broken the rock into two parts. Similarly can you observe and find names of trees which penetrate and break rocks.

Lesson 11:

Soil cycle.png

Soil Cycle:

  1. Take a handful of soil .Use a lens and write down what all you see in the soil.
  2. Connect to the components that you have observed with the given picture of the soil cycle. Discuss the same.
