Iqbal and His Ingenious Idea

It's monsoon season in Bangladesh, which means Iqbal's mother must cook the family's meals indoors, over an open fire. The smoke from the fire makes breathing difficult for his mother and baby sister, and it's even making them sick. Hearing them coughing at night worries Iqbal. So when he learns that his school's upcoming science fair has the theme of sustainability, Iqbal comes up with the perfect idea for his entry: he'll design a stove that doesn't produce smoke!
