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	Suggested Classroom Assessments	Vocabulary
1. Describe the effects of different types of forces (e.g., mechanical, electrical, magnetic) on motion.	Pulls and pushes are forces. A force can change the motion of an object. Earth is a giant magnet.			Students will use magnets to move objects. Students will use static electricity to move objects (balloon/hair) McGraw-Hill text p. 209 Do as a whole group Maine LAD Task: Keep on Trucking (also J2, Inquiry and Problem Solving and/or K4, Scientific Reasoning)	Students will describe how a magnet would affect a paper clip.	absorb attract effect of force electrical forces gravity magnetic mass mechanical motion reflect repel
2. Draw conclusions about how the amount of force affects the motion of more massive and less massive objects.	The heavier an object is, the harder you must pull it to get it to move.			Students will experiment moving smaller and larger objects and will learn to draw conclusions based on their observations. McGraw-Hill text Grade 3 p. 77	Students will be able to explain how the amount of force affects the motion of a VW and a motor home, or a bicycle and a car, or a chair and a table.
3. Generate examples illustrating that when something is pushed or pulled, it exerts a reaction force.	Force works in pairs. Whenever you push or pull on something, you feel a push or pull working in the opposite direction.			Students will brainstorm examples of reaction forces (i.e., swings, seesaws, tree branches, yo-yos)	Students will be able to demonstrate or draw pictures which illustrate that when something is pushed or pulled, it creates a reaction force.
