7.1: Forces & Motion 3 Dimensions & Progressions

Unit 1

STANDARD 7.1.2 ● Apply Newton’s Third Law to design a solution toa problem involving the motion of two colliding objects in a system. Examples could include collisions between two moving objects or between a moving object and a stationary object. (MS-PS2-1)

CONCEPTS

SKILLS

● Newton’s Third Law ● Colliding objects

● Design a Solution

LEARNING PROGRESSIONS

● A larger force causes a larger change in motion ● Motion of an object is determined by sum of forces acting on it ● The greater the mass of an object, the greater the force needed to achieve same motion

VOCABULARY ● Push ● Pull

● Weight ● Net Force ● Gravity ● Newton’s Law ● Inertia

● Momentum ● Velocity ● Acceleration ● Collision ● Mass

● Balance Force ● Unbalanced Force

● Speed ● Friction

POSSIBLE PHENOMENA ● A paper airplane can fy forward when dropped straight down. Engineering Challenge – Design and build a glider capable of fying 2X when dropped from a height of 1X. ● Sometimes when a person throws a water balloon at me I can catch it without it breaking and sometimes it breaks when I try to catch it. Engineering Challenge: Develop a device and/or method for catching water balloons that travel a specifed distance without breaking them. ● Slow Motion video of Golf Ball Collision/marble collision END OF UNIT COMPETENCY WITH LANGUAGE SUPPORTS ● I can apply Newton’s Third Law to design a solution to a problem involving the motion of two colliding objects

DIFFERENTIATION IN ACTION

Skill Building

Allow students many different opportunities to view Newton’s 3rd law in motion prior to designing a solution to a problem. ● Pop Can Engine ● Rocket Races
