Enjoy the hands-on experience of building and using the Bottle Racer, a modern adaptation of an old favorite. Explore the application of simple machines, energy conversion and investigate how changes in design affect performance.

Curriculum Topics: Simple machines, Stored Energy, Motion and Experimentation

### Standards

Idea Sheets are cross-referenced to subjects listed in the Common Core, Next Generation Science Standards, and California Content Standards.

Plan and conduct an investigation to provide evidence of the effects of balanced and unbalanced forces on the motion of an object. ||Next Generation Science Standards||Grade 3||Physical Science||Motion and Stability: Forces and Interactions |||Make observations and/or measurements of an object’s motion to provide evidence that a pattern can be used to predict future motion. [Examples: a child swinging in a swing, a ball rolling back and forth in a bowl, and two children on a see-saw.] “||Next Generation Science Standards||Grade 3||Physical Science||Motion and Stability: Forces and Interactions |||Plan and conduct an investigation to compare the effects of different strengths or different directions of pushes and pulls on the motion of an object. ||Next Generation Science Standards||Kindergarten||Physical Science||Motion and Stability: Forces and interactions |||Analyze data to determine if a design solution works as intended to change the speed or direction of an object with a push or a pull.||Next Generation Science Standards||Kindergarten||Physical Science||Motion and Stability: Forces and interactions |||Use evidence to construct an explanation relating the speed of an object to the energy of that object. ||Next Generation Science Standards||Grade 4||Physical Science||Energy |||Plan an investigation to provide evidence that the change in an object’s motion depends on the sum of the forces on the object & the mass of the object.||Next Generation Science Standards||Middle School||Physical Science||Motion and Stability: Forces and Interactions |||Develop a model to describe that when the arrangement of objects interacting at a distance changes, different amounts of potential energy are stored in the system. [Emphasis is on relative amounts of potential energy. Examples: the Earth & a roller coaster cart at varying positions on a hill, changing the direction/orientation of a magnet, & static electrical on a balloon.] [Assessment on two objects & electric, magnetic, & gravitational interactions.] ||Next Generation Science Standards||Middle School||Physical Science||Energy |||Construct, use, & present arguments to support the claim that when the motion energy of an object changes, energy is transferred to or from the object.||Next Generation Science Standards||Middle School||Physical Science||Energy
