I found this recipe on Foodnetwork.com. I haven’t made them yet but I bet they’re really good. CHEMISTRY INFORMATION: The pure substances are Baking Soda, Salt and Sugar. The Homogeneous mixtures are flour, vanilla extract, and Butter. The heterogenous mixtures are bananas, eggs, and chopped pecan. Also the batter before it is mixed. One physical change is when you whip up the ingredients besides the bananas and sugar.Another physical change is when the you add the bananas and sugar and mix them together and they turn into mush. A chemical change is when the muffins are in the oven and they are getting brown on the top. Another chemical change is the muffins puffing up as they cook. Submitted by: "Cassidy T"
