I don't put much emphasis on finding the right answer. I focus on the process. It takes a long time for the students to get it, but they find it's worth the struggle the first time they get that feeling of success. Mrs. Tindell also teaches importance of using the scientific method to her students. They each do science fair projects in the classroom rather than at home.
Students choose a project and do it in class.
Not all students will learn all the content in all areas, but they all learn the process. That is what is important. By doing it in class, they share the information they find. For example, last year, one student chose to do a project where they examined the effect of light color on mood. All the students in the class became the guinea pigs for the project and experienced the scientific discoveries of that student first hand.
