HOW DOES YEAST GROW? Team # 7
ALE F NATALIA SOFÍA
All organisms need energy to grow. They get energy from food. • A fungus is a plant that doesn´t make its own food. • Yeast is a fungus. It needs sugar from dead plants to grow. • The sugar gives yeast the energy it needs to stay alive and grow. • People use yeast to make dough for bread and buns.
OUR INVESTIGATION We wanted to see how yeast grows when we mix it with sugar, flour and water. • We took ¼ cup of warm water • 1 package of dry baker´s yeast • A glass jar • 1 cup of flour • 1 tablespoon of sugar • 1 spoon
We pushed the dough down into the bottom of the jar, and we measured how high the dough was.
We concluded that it is important to use yeast when we bake cakes or cookies
