MOTION & DESIGN
In this unit student learn that objects move in specific ways which are planned, powered, and designed using concepts such as: friction, air resistance and energy.
This unit uses the inquiry-based approach to teach content about the motion and design of vehicles. The emphasis is on Newtonian physics. The vehicle that students build in this unit is a working model and students are expected to collect data in science notebooks, read non-fiction selections, and design, build, test, and improve vehicles using K'Nex.
Students are assessed with an end-of-unit test, an end-of-unit performance assessment, and ongoing formative assessment of their notebooks using a proficiency feedback guide at the conclusion of each lesson.

NEWTONS LAWS OF MOTION
5.P.1.1 & 5.P.1.4
Newton's Laws of Motion & Predicting Motion Explain how factors such as gravity, friction, and change in mass affect the motion of objects. Predict the effect of a given force or change in mass on the motion of an object. |

Inertia means that an object in motion will stay in motion in the same direction, or will stay at rest, unless another force acts upon it. For an object to change direction or stop moving, something has to overcome inertia.
|
Acceleration is a change in velocity. That means acceleration can mean a change in speed or direction. Acceleration can be thought of as an object’s change in velocity over time.
|
Energy does not change, and that means it is constant. When one object applies force to another, the energy becomes an equal and opposite reaction.
|
Forces - Motion - DESIGN
Anytime there is a change in motion, force is the responsible party. It has to overcome inertia to act on an object. Inertia keeps an object either sitting still or moving at a constant speed.
|
Gravitational force is the constant force of attraction between the masses of two objects. The attraction between objects and the Earth is called gravity. Weight is caused by gravity: it is the measurement of gravity’s force on an object’s mass.

distance-time graphs - motion graphs
5.P.1.3
Illustrate the motion of an object using a graph to show a change in position over a period of time. |

PROPERTIES OF MATTER
Matter is anything that has mass and takes up space. That is why mass and volume are the properties of matter.
|
Physical changes mean matter changes size or shape, not its atomic makeup. Chemical and nuclear changes alter matter on an atomic level.
