There are many forces acting on all objects that causes it to move or stay in place. The forces that we will discuss are gravity (downward force) inertia (an objects ability to remain unchanged), and friction (opposing force of motion). All forces can be considered balanced (no change in motion) or unbalanced (change in motion). When objects are in motion, they move in a particular direction at a particular speed, which is velocity, which effects acceleration.
Students will view and complete activity on http://powermylearning.org/educator/activities (once on website type in forces, and select Forces and movement) to have virtual practice and to observe the effect of forces on an object based on its mass and the amount of force acting on the object. The students will then complete the 10 question quiz (Print quiz score for proof of practice) after manipulating the activity. Students will also view applying forces for velocity practice and Forces and Motion: Basics.
After the students have complete understanding of velocity, forces acting on objects, and how mass effect the movement of objects, the students will complete force diagram, including the following:
*After achieving full comprehension, students will be provided the rubric for force diagram project
*Student will complete force diagram, Including the following:
-Illustration of object
-labeled forces
-amount of force in Newtons
-arrows to show direction of force
-Net force and overall direction of object
-Scenario explaining how the object movement would change if the mass was greater or lesser and the force stayed the same.
*Teacher will distribute I-pads
*Students will go to the following website (http://powermylearning.org/educator/activities
*Students will type in forces then select forces and movement
*Students will practice forces and movement by manipulating the car size and the amount of force being provided and observe the velocity of the object
*Students will then take the 10 question quiz (Print quiz score)
*Students will then visit applying forces to practice velocity
*Students will then visit Forces and Motion: Basics for the different types of forces on surfaces
*I-pads will be collected
**At home application and completion of Force Diagrams**
*After achieving full comprehension, students will be provided the rubric for force diagram project
*Student will complete force diagram, Including the following:
-picture of object
-labeled forces
-amount of force in Newtons
-arrows to show direction of force
-Net force and overall direction of object
-Scenario explaining how the object would move if the mass was greater or lesser and the force stayed the same.
*Students will have 3 checkpoints prior to the due date for final project.
***Prior to the project the students would receive notes, multiple activities for practice, and mini weekly assessments.
Students will be given a rubric that will provide them with specific information. The Rubric will be used to evaluate the students comprehension of the learning target. The rubric is below:

Total______/100
Students will be able to clearly identify forces acting on all objects.
Students will be able to demonstrate the effect of balanced and unbalanced forces acting on an object in terms of gravity, inertia, and friction.
Students will be able to communicate why an object will move in a particular direction and the net force being applied.
Students will be able to determine how the movement of an object is effected by the mass of the object.

Mrs. Rhea-Neely (Rubric)
Rubric will be distributed to students two weeks prior to the due date of the project. Students will have 3 checkpoints prior to the final project to ensure that progress is occurring. I will review the rubric with the students the day it is distributed and 1 week prior to the due date.
-Students will have notes on force, mass, and motion
Velocity and acceleration is included
-Students will have had mini-weekly assessments
-Homework assignments
-Terminology practice (Frayer Models)
