"Ward's+Phenomena"

Used to determine if bacteria produce extracellular enzymes to catalyze the hydrolysis of starch. Organisms that produce a starch hydrolyzing enzyme will display a clear zone around the area of growth while other areas of the agar containing starch will turn blue-black.

To prepare media, add 20 g of phenol red dextrose broth to a liter of distilled or de-ionized water. The media will not be sterile until autoclaved prior to use.

Hands-on investigation even explores light separation.

This Pendulum kit is an excellent model for investigating energy.
