When the Sun rises: 1. How does the sky look? 2. What do the birds and animals do? 3. What changes do we find at home?
The sky looks orange in colour during sunrise, and the Sun also appears orange. As the Sun rises higher, the sky gradually becomes bright and blue.
Birds and animals become active during sunrise. Birds start chirping, leave their nests, and begin searching for food. Animals also start their daily activities.
At home during sunrise, people wake up from sleep, morning routines begin, artificial lights are switched off as sunlight enters the house, and household activities start.
