This recipe came from and I want to share it because I really like blueberry muffins. CHEMISTRY INFORMATION: The pure substances are white sugar and salt. The ingredients that are homogeneous mixtures are all purpose flour, baking powder, vegetable oil, milk, butter,and cinnamon. The heterogeneous mixtures are the egg and the blueberries. Physical changes that are happening is when the ingredients are being mixed and when you put the batter in the cupcake holders. The batter turning into the muffin and the muffins puffing while they bake show that chemical change is happening . Submitted by: "Annalisa D"
