This is the original recipe that Ruth Wakefield made back in 1937. It's a little different from the recipe on the back of the Nestle Tollhouse Chocolate Chip bag.
This article is from Wonderopolis about the woman who invented chocolate chip cookies. Chocolate chip cookies were actually an accident. In 1937, Ruth Wakefield was making her butter cookies when she realized she was out of bakers chocolate, so she chopped up a bar of semi-sweet chocolate and put it in the dough. When she took them out of the oven, she discovered that the chocolate bits had not melted like the baking chocolate did. She invented a new cookie!
This is a class from King Arthur Flour. It teaches kids math and science while they make bread dough that can be made into 2 loaves of bread (or one loaf of bread and 2 pizza crusts). The kids keep one loaf of bread for themselves and give one loaf away to make someone's life a little better.
In this article by Wonderopolis, kids learn why food rises when they bake it. This article teaches about yeast and what happens when yeast is mixed with sugar. Carbon dioxide forms, which makes the dough rise. There are also experiments at the end of the article to learn more about yeast.
