Kasi and Danaah's STEM Adventure

Once upon a time, in a cozy little house at the end of a winding road, lived two curious siblings named Kasi and Danaah. Kasi was eight years old, with big brown eyes that sparkled with excitement whenever she discovered something new. Danaah, her younger sister, was six years old, with a mischievous grin that always got them into fun adventures.
