A kindergarten class learns about inventions, inventors, and how to be an inventor. Engaging students in learning about pencil sharpeners led to researching and developing a lesson plan designed so students could learn how inventions are solutions to problems. Through identifying, researching, and brainstorming new inventions, the students practiced inventing a solution for a mock problem. As a class, in small groups, and individually, students were able to use scientific inquiry by posing questions, designing, and building solutions with natural and human-made materials. They tested their inventions, revised them, and reported results to the class. This lesson integrated subjects such as language arts, social studies, math, and art while meeting national science education standards. (Contains 2 figures and 1 table.)
