Content Standard: I. Motion:
Students will understand the motion of objects and how forces can change that motion.
Common Assessment(s):

Performance Indicators Students will be able to	Essential Elements (Specific grade level learning objectives)			Suggested Performance Activities (Relating to Assessments)	Suggested Classroom Assessments	Vocabulary * Indicates a word the teacher uses to help students start to understand
1. Develop a variety of ways to describe the motion of an object.	Describe the motion of an object in a variety of ways			Introduce Ramps and Cars experiments Resources: View Ramps and Sledding in Bath http://www.bathpu blicschools.com/f ms/grade2/scienc e/sleddingwithow ney.htm Balances.

MAP Task: Paper Drop	Explain your seat belt demo (clay person on car hitting ruler). When the ramp gets higher the clay person goes farther. The higher ramp will make the faster the car . Possibly Common Assessment Maine LAD Task : Rolling and Sliding	Angle Backward Distance Down Fast Force Forward *Friction *Fulcrum *Infer Lever Motion *Pivot Predict Pull Push Ramp Simple machine Slant Slow Straight Up Weight Zigzag
2. Demonstrate that the motion of an object can be changed.	Explain how to change the motion of an object			Ramps and Cars Create several ramps. Change the height of the ramp. Test the distance that a small car can go with when the height is changed.	Given a a matchbox type of car or a ball and material to make a ramp, the students will predict how changing the angle of the ramp will affect either the speed or the distance that the car or ball will travel.
