• Cooking Time: One hour
• Servings: One loaf
• Preparation Time: 30 min
• 1 cup of sugar (pure substance C12H22O11)
• 2 eggs (heterogeneous mixture)
• 3 bananas, mooshed (heterogeneous mixture)
• 4 tablespoons of butter- melted (homogeneous mixture)
• 1 ½ cup of flour (homogeneous mixture)
• ½ teaspoon of salt (pure substance NaCl)
• 1 teaspoon of baking soda (pure substance NaHCO3)
• chocolate chips (optional) (homogeneous mixture)

1. First you take a large sized bowl and put 1 cup of sugar in the bowl. Then you put 2 eggs in the bowl. Also put put 3 bananas, mooshed in the bowl. Then put the following ingredients into the bowl: 1 ½ cup of flour, ½ teaspoon of salt , 1 teaspoon of baking soda.
2. Then put 4 tablespoons of butter but you have to put the butter into a microwave so it is melted and then put it in the bowl. Then you could put chocolate chips (optional) if you want.
3. Then you mix it all up and grease a pan then put the banana bread mix into the pan.
4. Then set the oven for 350 degrees and put the banana bread in for an hour.
5. After an hour take it out of the oven with oven mittens.
6. Wait for it to settle for 30 minutes and then you can eat it.

I chose banana bread for this project because it was my Great Grandmother’s recipe and I want to pass it on through the family. CHEMISTRY INFORMATION: Bananas and eggs are heterogeneous mixtures. Sugar, butter, flour, and chocolate chips are homogeneous mixtures. Salt and baking soda are pure substances. A couple physical changes are mixing all the ingredients. Another would be melting the butter in the microwave. A couple chemical changes would be putting the banana bread in the oven going from a liquid to a solid. Another one would be the banana bread getting burnt in the oven at the bottom if you leave it in the oven too long. Submitted by: "Vanessa D"
