Do boys and girls learn and understand Sciences in the same manners?

Studies show that boys learn differently than girls. Brain scans tell part of the story. In general, more areas of girls' brains, including the cerebral cortex (responsible for memory, attention, thought, and language) are dedicated to verbal functions. The hippocampus -- a region of the brain critical to verbal memory storage -- develops earlier for girls and is larger in women than in men. "That has a profound effect on vocabulary and writing," Gurian says.

In boys' brains, a greater part of the cerebral cortex is dedicated to spatial and mechanical functioning. So boys tend to learn better with movement and pictures rather than just words, Gurian says.

There are also biochemical differences. Boys have less serotonin and oxytocin -- hormones that play a role in promoting a sense of calm -- than girls. That's why it's more likely that young boys will fidget and act impulsively.
