Exploring Life Cycles in 4th Grade Science

The video tutorial explores the concept of life cycles across different organisms, including animals and plants. It explains how life cycles involve growth, development, and reproduction, starting with eggs in animals like chickens and frogs, and seeds in plants. The video also covers metamorphosis in animals such as frogs and insects, highlighting the significant changes they undergo. Additionally, it describes the plant life cycle from seed germination to flowering and seed production.

• Only the shell

• Nutrients and water

• Everything needed for development

• They don't have a pupa stage

• They skip the egg stage

What is the first step in a plant's life cycle?
