Yes, technology really changes children's activities, especially as they spend more time on screens. Now, with tablets and smartphones, kids spend more time sitting and less on physical activities. This change can affect their physical health and how they develop social skills.

Technology's effect on children's activities depends on its use. If used right and not too much, it can help in learning. But too much or without supervision can reduce physical activity and direct social interaction. The key is to balance screen time with other activities for children's overall development.
