Teacher Resource Pack: Adapted for WAKE COUNTY Unit Planning Resources Subject Area/Grade: Physical Science, grade 5 Unit Theme: Motion & Design Conceptual Lens: *Systems, Order, Organization *Evidence, Models and Explanation Identify the Big Ideas: (Align to Essential Standards) Force and Motion Interactions Gravity Enduring Understanding (Generalizations) Nothing in the universe is at rest. Motion is as essential to understanding the physical world as matter and energy are. All motion is relative. All motion is governed by the same basic rules. Gravity is an attractive interaction. The earth's gravity pulls any object on or near the earth toward it without touching it. A gravitational field is caused by an object with mass. Changes in speed or direction of motion are caused by forces. The greater the force is, the greater the change in motion will be. The more massive an object is, the less effect a given force will have. The motion of an object can be described by its position, direction, motion and speed. Title: Force and Motion Estimated Time Frame: 23 days GRAPHIC ORGANIZERS: NC Science Essential Standards; Physical Science Domain; Forces and Motion strand Atlas of Science Literacy page 62-63, Laws of Motion How do forces affect objects? http://www.eduplace.com/science/hmsc/content/organizer/3/org_3f_15_1.pdf How Can motion be described? http://www.eduplace.com/science/hmsc/content/organizer/3/org_3f_15_2.pdf http://www.eduplace.com/science/hmsc/content/organizer/4/org_4f_16_1.pdf Newton’s Laws of Motion Inspiration example http://www.inspiration.com/inspiration-science-examples Qwiki graphic organizers: force http://www.qwiki.com/q/#!/Force gravity http://www.qwiki.com/q/#!/Gravitation NC Science Essential Standards 5.P.1 Understand force, motion and the relationship between them. 5.P.1.1 Explain how factors such as gravity, friction, and change in mass affect the motion of objects. 5.P.1.2 Infer the motion of objects in terms of how far they travel in a certain amount of time and the direction in which they travel. 5.P.1.3 Illustrate the motion of an object using a graph to show a change in position over a period of time. 5.P.1.4 Predict the effect of a given force or a change in mass on the motion of an object. Essential Questions (Guiding Questions) What is the origin of motion? How are motion and gravity connected? What is gravity? How does gravity ‘work’? How are gravity and mass connected? How are force and motion connected? How can we describe their relationship? How can we model the relationship of position, motion, direction and speed? Motion can be measured and represented on a graph. Essential Terminology: WAKE COUNTY acceleration: rate of increase of speed or velocity (example: accelerator pedal on a car) air resistance (drag): force of air pushing against the motion of an object balanced force: an object remains in place, no movement occurs control: part of an experiment that does not change, serves as the standard to compare other observations direction: the way the force is applied determines this way an object moves energy: ability to do work energy, kinetic: energy of motion (moving ball going down a ramp) energy, potential: stored energy (ball positioned at the top of the ramp) fair test: changing only one variable and keeping the other conditions the same force: any push or pull on an object friction: force that resists motion between two touching surfaces, slows things down and can also produce heat, acts in the opposite direction of the force gravity, gravitational force: force that brings objects toward earth inertia: the tendency of an object to resist a change in motion or keep doing what it is doing Note: the greater the mass of an object, the greater the inertia mass: how much matter an object contains momentum: force or speed of movement; mass in motion, example: a moving train has much more than a moving soccer ball Note: momentum = mass of an object x velocity (increasing the mass or speed increases the momentum) motion: an object changing position over time; change in position is measured by distance and time Newton’s 1st law of motion: *An object tends to stay at rest and an object tends to stay in motion with the same speed and in the same direction unless acted on by an unbalanced force. * Objects tend to keep doing what they are doing. * If the forces acting upon an object are balanced, the acceleration of that object will be zero (no motion). *also known as the “law of inertia” Newton’s 2nd law of motion: * Acceleration is always in the direction of the unbalanced force. *If you want something to accelerate faster, you need to decrease its mass. * Acceleration of an object depends upon two variables—the net force acting upon the object and the mass of the object. * Force = mass x acceleration or F = ma Newton’s 3rd law of motion: *Explains why forces act in pairs. * For every action, there is an equal and opposite reaction. * When one object exerts a force on a second object, the second object exerts the same amount of force back on the first object (but in the opposite direction). * Equal forces acting in opposite directions create a net force of zero. * Action and reaction forces are equal forces acting in opposite directions. The reason they can’t cancel each other out is because they are acting on different objects. propeller: two or more twisted blades that rotate around a central point or shaft (shaft: pipe or tube) recursive: consequential steps resistance: force pushing against the motion of an object speed (rate): distance divided by time (or d/t), example: 25 mph unbalanced force: motion occurs; the movement goes in the direction of the greater force (example: winning a tug-of-war game) validity: conducting a fair test variable: something in an experiment that can be changed velocity: speed with direction (ex.: 45 mph NW) weight: force of gravity pulling down on an object work: moving an object over a distance Identify Misconceptions *Construct formative assessment probes – see ‘how to’ on pages 85, 102, and 183 in Science Formative Assessment by Page Keeley.

Students know that friction is a force that is created anytime two surfaces move or try to move across each other. Students know that all matter has mass. Students understand that changing any or all of these factors will affect the motion of an object. 5.P.1.2 Students know that it is possible to measure the motion of an object based on the distance it will travel in a certain amount of time. 5.P.1.3 Students know that a graph can be created using one axis to represent the distance that an object travels, and the other axis to represent Science For All Americans Motion is as much a part of the physical world as matter and energy are. Everything moves—atoms and molecules; the stars, planets, and moons; the earth and its surface and everything on its surface; all living things, and every part of living things. Nothing in the universe is at rest. Since everything is moving, there is no fixed reference point against which the motion of things can be described. All motion is relative to whatever point or object we choose. Thus, a parked bus has no motion with reference to the earth's surface; but since the earth spins on its axis, the bus is moving about 1,000 miles per hour around the center of the earth. If the bus is moving down the highway, then a person walking up the aisle of the bus has one speed with reference to the bus, another with respect to the highway, and yet another with respect to the earth's center. There is no point in space that can serve as a reference for what is actually Benchmarks Reference 4F 4G the period of time the object is traveling. Students know how to construct a graph that demonstrates a relation of distance to time. 5.P.1.4 Students know that the greater a force is, the greater the change (in motion) it produces. The greater the mass of the object being acted on, the less the effect of the (same) force. moving. Changes in motion—speeding up, slowing down, changing direction—are due to the effects of forces. Any object maintains a constant speed and direction of motion unless an unbalanced outside force acts on it. When an unbalanced force does act on an object, the object's motion changes. Depending on the direction of the force relative to the direction of motion, the object may change its speed (a falling apple) or its direction of motion (the moon in its curved orbit), or both (a fly ball). The greater the amount of the unbalanced force, the more rapidly a given object's speed or direction of motion changes; the more massive an object is, the less rapidly its speed or direction changes in response to any given force. And whenever some thing A exerts a force on some thing B, B exerts an equally strong force back on A. For example, iron nail A pulls on magnet B with the same amount of force as magnet B pulls on iron nail A—but in the opposite direction. In most familiar situations, friction between surfaces brings forces into play that complicate the description of motion, although the basic principles still apply. Everything in the universe exerts gravitational forces on everything else, although the effects are readily noticeable only when at least one very large mass is involved (such as a star or planet). Gravity is the force behind the fall of rain, the power of rivers, the pulse of tides; it pulls the matter of planets and stars toward their centers to form spheres, holds planets in orbit, and gathers cosmic dust together to form stars. Gravitational forces are thought of as involving a gravitational field that affects space around any mass. The strength of the field around an object is proportional to its mass and diminishes with distance from its center. For example, the earth's pull on an individual will depend on whether the person is, say, on the beach or far out in space.
