Can we grow plants without germinating their seeds? Explore and cite some examples.

Observe the life cycle of five plants grown at home, school, or in a nearby garden. Create a picture book containing pictures of various stages of their growth. Write the name of each plant and the duration of each of its stage.

Try to observe some of the stages in the life cycle of a butterfly or a moth. Are these stages similar to the stages in the life cycle of a mosquito?

In your opinion, would the environment affect the life cycles of insects? Explore and list the factors that affect the life cycles of insects.

Add more lines to the incomplete poem given below. Include information on the different stages in development of a frog. You may also draw and paint each stage as it appears in your poem.
