Teacher Name:
 Paige Moore
Grade:
 Grade 7-8
Subject:
 Science

Topic:
 Gravity and Forces
Content:
 gravity free fall terminal velocity friction magnitude balanced force unbalanced force net force newton Isaac Newton
Goals:
 All students will master at least 80% of the content evaluated by Friday's test. Those students who do not meet 80% mastery will correct their tests over the weekend and retest on Monday.
Objectives:
 PS A.2.a To ananlyze the direction and effects of forces in a variety of situations. (e.g. gravity and friction) PS A.2.b Compare and contrast forces that are balanced and unbalanced. PS A.2.c Use arrows to illustrate the magnitude and direction of a force applied to an object. PS A.2.d Analyze the effect of an unbalanced force on an object's motion in terms of speed and direction. PS A.2.e Analyze the effect of balanced forces on an object's motion in terms of speed and direction. PS A.2.f Predict what happens to an object at rest or an object in motion when unbalanced forces act upon it. PS A.2.i Describe the motion of an object in free fall.
Materials:
 overhead projector
Introduction:
