What have you created scientifically whenYou add flour sugar brown eggs vanilla extract and butter to a large bowl stir?

You haven't created anything scientifically by just adding those ingredients to a bowl and stirring. You've created a mixture.

Here's why:

* Scientifically, a mixture is a combination of two or more substances where each substance retains its own properties. In this case, you have flour, sugar, eggs, vanilla extract, and butter, each keeping its individual characteristics.

* To create something new scientifically (like a new compound), you would need a chemical reaction. Baking does involve chemical reactions, but they occur when you add heat and the ingredients interact.

So, your bowl of ingredients is just a mixture, but it's a starting point for a chemical transformation that will turn it into cake or cookies!
