In 2nd through 4th grade, we are not just learning about simple machines, we are practicing fine motor skills, spatial awareness, planning, problem solving, perseverance, and working together.
We started with an introduction to the different types of simple machines, then began exploring and engineering with each. This week, we built gear sequences, and students designed/began designing structures with wheels. They learned that scientists and inventors usually have to spend a lot of time fixing problems and trying new things before their products work. They've been working together to come up with ideas and solve problems.
