PROCEDURE:

Obtain water-washed beet cubes and three alcohols. Set up nine test tubes so as to obtain data for the chart below. (Serially dilute your alcohols: 8M, 4M, 2M).
Let stand for 20 minutes, then shake the tubes.
Record qualitative observations as to the color (dark red to colorless) of the liquid in the tubes.

Alcohol [...]

TARGET AUDIENCE
Secondary school students, grades 9-12
OBJECTIVES
Using two point discrimination on the skin, students will determine the relative number of nerve endings located in the skin. By calculating the reciprocal of these measurements, the students will have the appropriate data for predicting the relative size and drawing the homunculus found on the cerebral cortex. Comparisons will [...]
