Mouse Brain/Human Brain Demonstration
Materials needed: old worksheets, small bowl, marker cap, pencil
Ask students to imagine that the bowl is a human skull and the marker cap is a mouse skull. (Using models of real skulls would make this activity more exciting!) The worksheets represent "information". Have students fill their "mouse skull" with "information" by tearing off a small piece of worksheet, rolling it into a loose ball, and fitting it into the marker cap. Next, have them take one piece of information and lay it on top of the bowl, and ask "Does it fit?" The answer is "no", but they should soon discover that if you crumple the paper, it will fit. Students should fill their "human brain" with as much "information" as possible by crumpling worksheets and pushing them into the bowl. Have students empty out both "brains" and examine the contents. Obviously the human brain, being much larger, was able to store more information, but crumpling the paper allowed it to hold much more. This is the reason for the gyri and sulci; the surface area of the brain is greatly increased, and this is where the connections for higher functioning take place.
