Science teachers may want to add doodling to their lesson plans, say researchers who found the freehand drawing may help students learn science.

It is much easier to draw than drawing a picture of the beaker. Cross-section diagrams are used in science to help make scientific diagrams of apparatus clear and easy to understand what they show.

Students who are allowed to draw to explain science terms are more likely to understand key concepts than those restricted to traditional methods.
