Cinthia decided to find out if it was worth spending the money to buy bags of potting soil sold at the store. She bought one bag of potting soil and some bean seeds. At home she put potting soil in ten pots and soil she dug up from her yard in ten other pots. She planted one bean seed in each pot. After one week, all twenty seeds had sprouted and all the seedlings had two leaves. She concluded that her soil was just as good as potting soil. What would be the best thing for Cinthia to do next?
