Koby wanted to do an experiment where he could observe a chemical reaction. He decided that he was going to combine baking soda with water and with vinegar and see whether either one created a chemical reaction. Koby placed ½ teaspoon of baking soda into each of two identical glasses. He noticed the baking soda was lumpy, so he used a fork to break up the lumps. Why is it important to break up the lumps?
