Carol and Sam took a package of yeast and poured it into some warm water. Yeast is something your mother or dad might use when baking bread. Yeast helps the bread to rise. After an hour, the students noticed that the yeast solution was bubbling. They used a dropper to make a microscope slide of some of the liquid containing the yeast. This is what they saw. Carol said that she thought yeast was a living thing. Sam thought she was wrong. What do you think? Explain.
