Students will compare three different types of sugar cookies: class-made from scratch, ready-made dough for cookies, and boxed cookies.

1. Show the class the three different types of cookies (or ingredients) and ask your class which cookies (out of the three) will taste the best. What is their reasoning?
2. Have students help bake the ready-made dough cookies. You can cut them into Valentine shapes and decorate.
3. Have students make the from-scratch cookies using the ingredients provided. These can also be molded or cut into shapes.
4. When all of the cookies have been prepared, lay out each set separately and have students taste them.
5. After the taste-test, graph the opinions for each type of cookie and discuss why the home-made (should!) taste the best.
