Ramp bowling design challenge (Grade 2)
Grade: Two
Topic: Understanding structures and mechanisms, movement
Design Challenge:
Teachers and students work collaboratively to identify an environmental challenge regarding the use of cardboard and plastic. Using their background knowledge of the types of simple machines, the group will then collaborate on a solution by suggesting ways to make a toy that uses two simple machines and includes the use of plastic bottles and/or cardboard tubes. From there the teacher will narrow down the choices to the type and number suited to the group's capabilities. In this case the focus will be on reusing small plastic bottles and/or cardboard tubes to make golf ball bowling ramp game.
