This chapter teaches fundamental separation techniques, fostering critical thinking and problem-solving skills essential for scientific inquiry. Understanding these methods encourages curiosity and experimentation, vital traits for aspiring scientists in exploring and analyzing the world around us.

The lighter component, the husk, gets blown away by the wind. The heavier wheat grains remain closer to the platform due to their weight, making them less susceptible to being carried away by the air.

The time farmers take to separate grains from husk varies based on methods used. Traditional winnowing can take several hours, while mechanical winnowers significantly reduce this time, completing the process in minutes for larger quantities.
