Lesson Plan


Students were asked to use what they learned about simple machines to create an invention. They were guided through the invention process: finding problems and then creating solutions to those problems. The students not only created their inventions, but also made a display board to go along with their invention. All students' inventions were then displayed during our Grade Three Invention Convention. Teachers used the rubrics to grade the assignment, students and parents used them to help design their display board and invention. The Invention Convention was the culminating project to our unit on simple machines and our entire year of science.
