Standards

Physical Science: Forces and Motion
- 5.P.5 The student will demonstrate an understanding of the factors that affect the motion of an object.
  - 5.P.5A The motion of an object can be described in terms of its position, direction, and speed. The rate and motion of an object is determined by multiple factors.
    - 5.P.5A.2 Develop and use models to explain how the amount or type of force (contact and non-contact) affects the motion of an object.
2.MDA Measurement and Data Analysis
- 2.MDA.1 Select and use appropriate tools (e.g., rulers, yardsticks, meter sticks, measuring tapes) to measure the length of an object.
- 2.MDA.2 Measure the same object or distance using a standard unit of one length and then a standard unit of a different length and explain verbally and in writing how and why the measurements differ.
Science and Engineering Practices
- 2.S.1 The student will use the science and engineering practices, including the processes and skills of scientific inquiry, to develop understandings of science content.
  - 2.S.1A The practices of science and engineering support the development of science concepts, develop the habits of mind that are necessary for scientific thinking, and allow students to engage in science in ways that are similar to those used by scient...
