Science SCI.IV.3.1 Strand: Using Scientific Knowledge in Physical Science - Motion of Objects Standard: Benchmark: Grade: 1 All students will describe how things around us move, explain why things move as they do, and demonstrate and explain how we control the motions of objects. Describe and compare motion of common objects in terms of speed and direction. Constructing and Reflecting: SCI.I.1.1 - Generate reasonable questions about the world based on observation. SCI.I.1.3 - Manipulate simple devices that aid observation and data collection. SCI.II.1.2 - Show how science concepts can be illustrated through creative expression such as language arts and fine arts. Vocabulary Context Direction words – east, west, north, south, right, left, up, down Speed words – fast, slow, faster, slower Motions of familiar objects on two dimensions, including rolling or throwing balls, wheeled vehicles, sliding objects. Knowledge and Skills Resources Coloma Resources: Students will describe, compare or demonstrate the motion of objects in terms of speed (fast, slow, speeding up, slowing down) and direction (right, left, east, west, north, south, up, down).

What is faster than a speeding cheetah? Whitman, 1997 Instruction Assessment Benchmark Question: How does speed and direction affect the motion of objects? Focus Question: How do you describe the movement of an object? • • • Required: Students will describe the motion of a ball that has been kicked, rolled, thrown in terms of speed, direction and change of direction using precise description. Vocabulary to be included: fast, faster, slow, Teacher will label the classroom with direction slower, left, right, (up, down) north, south, east, and west. signs (N,S,E,W) The class will observe the flight of a paper airplane discussing and listing its motion in terms of speed and direction. In pairs, students will select words from a hat and act out the movement of an object demonstrating the selected speed and direction words. Direction Words: North South East West Left Right Speed words: fast slow faster slower (Give students rubric prior to assignment) Scoring Rubric Criteria: Description Beginning (60%) – Describe movement using both direction and speed vocabulary, less detail in identifying the change in speed and direction. Developing (80%) – Describe movement using both directional and speed vocabulary, also identifying change in speed and direction. Secure (100%) - Describe movement using both directional and speed vocabulary, identifying change in speed and direction and acknowledges factors that cause change. Teacher Notes: Describe how things around us move, explain why things move as they do, and demonstrate and explain how we control the motion of objects. Young children should become acquainted with the scientific descriptions of the motion of objects, which generally includes discussion of speed, direction and changes in speed or direction. The understanding of the force/motion relationship can become increasingly quantitative, as the students get older. Instruction should be included which will help students overcome a common belief that sustained motion always requires sustained force. Early elementary students can develop a foundation for understanding magnetic attraction through various investigations of magnetism. Determining categories of objects that are attracted to a magnet, distances through which a magnet will attract objects and how many small objects a particular magnet will attract helps children consolidate their experiences into scientific knowledge. Elementary students should be able to understand that simple machines are devices controlling forces. A lever can transform a small downward force into a large upward force thus making a task easier. Simple machines help us to accomplish tasks that would otherwise be impossible. Young children can see simple machines all around them. Homes and playgrounds offer rich experiences for children to experiment with concepts related to simple machines.
