Have you seen or used tools at home? Chances are you have used a simple machine more than once! Simple machines begin with six basic instruments that help humans work more efficiently and provide mechanical advantage to performing tasks. While many simple machines operate work with moving components, some machines perform tasks by remaining stationary. Learn about Newton's three laws of motion and how they apply to the forces at work!

United States

Define a simple design problem reflecting a need or a want that includes specified criteria for success and constraints on materials, time, or cost.

NGSS

3-5-ETS1-1

Generate and compare multiple possible solutions to a problem based on how well each is likely to meet the criteria and constraints of the problem.

3-5-ETS1-2

Plan and carry out fair tests in which variables are controlled and failure points are considered to identify aspects of a model or prototype that can be improved.

3-5-ETS1-3

Define the criteria and constraints of a design problem with sufficient precision to ensure a successful solution, taking into account relevant scientific principles and potential impacts on people and the natural environment that may limit possible solutions.

MS-ETS1-1

Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.

MS-ETS1-2

Students develop, test and refine prototypes as part of a cyclical design process.

ISTE Students

1.4.c Innovative Designer

Students communicate complex ideas clearly and effectively by creating or using a variety of digital objects such as visualizations, models or simulations.

1.6.c Creative Communicator

Apply Newton’s Third Law to design a solution to a problem involving the motion of two colliding objects.*
