3 Third GradeTHIS UNIT BUILDS KNOWLEDGE FROM KINDERGARTEN AND IS A PREREQUISITE FOR: Middle School: Forces and InteractionsABOUT THIS UNIT: This unit is intended to build on the experiences and understandings of Forces and Interactions from the Kindergarten Unit, Motion: Pushes and Pulls. Students made observations, internalized questions about those observations, and investigated through trial and error, allowing them to anticipate, interpret, and make sense of the motion of objects. This unit builds and refines those ideas into forms that enable more subtle inferences about objects and their behaviors over intervals of time and space.

4 They form a better sense of causation and recognition of patterns in the motion of objects. In this unit the activities are geared to build on the inherent knowledge and experience that third- grade students have already acquired and use their knowledge in a wider range of tasks. Students will be given the opportunity to examine, measure, reflect upon, describe, and discuss how Forces of various origins are used to produce and control motion. They may be asked to analyze what they are already taking for granted. Students will look at things from a different perspective and consider what they may have previously overlooked.

5 Forces and Interactions is designed for third- grade students, and as a result of these lessons, students will be able to: 1. Observe and measure the motion of objects to discover patterns in Recognize patterns in data to use to make predictions of future Manipulate materials to change the motion of an object with contact Forces based on patterns of motion. 4. Collect and communicate evidence that multiple Forces have strength and direction and act on objects (balanced and unbalanced Forces ). 5. Manipulate materials to change the motion of objects not in contact with one another using electric or magnetic Interactions .

6 6. Demonstrate, through solving an engineering problem, how magnetism can be used to change the motion of an object. UNIT INTRODUCTION4 PLANNINGNEXT GENERATION SCIENCE STANDARDSD isciplinary Core Ideas : Forces and Motion Each force acts on one particular object and has both strength and a direction. An object at rest typically has multiple Forces acting on it, but they add to give zero net force on the object. Forces that do not sum to zero can cause changes in the object s speed or direction of : Types of Interactions Objects in contact exert Forces on each ,2,3,4,63-PS2-1.

7 Plan and conduct an investigation to provide evidence of the effects of balanced and unbalanced Forces on the motion of an object. 1,2,3,4, : Forces and Motion The patterns of an object s motion in various situations can be observed and measured; when the past motion exhibits a regular pattern, future motion can be predicted from it. 1,2,3,4,5,6,3-PS2-2. Make observations and/or measurements of an object s motion to provide evidence that a pattern can be used to predict future motion. 1,2,3,4,5, : Types of Interactions Electric and magnetic Forces between a pair of objects do not require that the objects be in contact.

8 The sizes of the Forces in each situation depend on the properties of the objects and their distances apart and, for Forces between two magnets, on their orientation relative to each other. 7,83-PS2-3.
