Thursday, January 24, 2013 MICHIGAN K.I.D.S. | WWW.DNIE.COM yeast and either baking soda, flour, salt or sugar. Nothing happened in the first three flasks. But sugar caused a violent reaction in the fourth. “It blew up!” said Josh Prim, 11, a Detroitarea 5th grader. Richard said the reaction is called cellular respiration. “That’s a process in which the enzymes in yeast take sugars and transform them into energy and CO2,” or carbon dioxide, a gas. Josh and his sister, Kayla, 9, were impressed. “Yeast helps dough to rise,” Richard said. “Do you think it’s alive or non-living? It doesn’t look like a plant, and it doesn’t look like an animal, but it’s alive.” How cool is that? Congratulations to everyone involved in giving us back our science center!
