##### Description

Science Objects are two hour on-line interactive inquiry-based content modules that help teachers better understand the science content they teach. This Science Object is the first of four Science Objects in the Force and Motion SciPack. It provides an understanding of how changes in position and motion can affect the way objects move, focusing on constant motion (where the direction and speed remain the same) and acceleration (a change in motion due to a change in an object’s direction or speed). The position of an object must be described relative to some other object while the motion of an object can be described by its direction and speed. Velocity is a measure of both an object’s speed and its direction (and can be described by vectors).

## Ideas For Use

Science Objects are two hour learning experiences teachers can use to enhance their understanding of a particular scientific concept. Teachers can access any topic “on demand” from the Internet. Topics are based on the science literacy goals in the national standards (NSES, Science for All Americans, Benchmarks, and the Atlas of Scientific Literacy) and tied to state standards.

Each Science Object provides an understanding of the science content by providing a structured set of learning experiences through simulations and practice assessments. Science Objects challenge teachers to explore and explain real world phenomena and are founded on the principle that learners must be challenged with a problem, observation, data, etc., in order to develop scientific understanding. Science Objects utilize the five phases of inquiry-based learning: Engage, Explore, Explain, Elaborate, and Evaluate.

Learning Outcomes:

Force and Motion: Position and Motion

• Identify the position of one object relative to the position of another object by providing the approximate distance and angles between the objects, the angles being measured from some reference line.
• Define the concepts of speed and velocity.
• Determine the average speed of an object given necessary information.
• Describe, draw, or otherwise detail the velocity of an object given magnitude and direction.
• Define acceleration.
• Recognize examples of acceleration and provide examples of acceleration.
• Distinguish between constant and changing motion.
• Distinguish increasing speed from increasing acceleration.
• Recognize that the state of rest is a state of zero speed (rather than as something fundamentally different than motion).

 Science Discipline: (mouse over for full classification) Acceleration Speed Vectors Velocity Intended User Role: Elementary-Level Educator, High-School Educator, Middle-Level Educator, New Teacher, Teacher Educational Issues: Inquiry learning, Learning theory, Professional development, Teacher content knowledge

• Physical Science
• Position and motion of objects
• An object's motion can be described by tracing and measuring its position over time. (velocity) (K-4)
• The position and motion of objects can be changed by pushing or pulling. (K-4)
• Motion and Forces
• The magnitude of the change in motion can be calculated using the relationship F = ma, which is independent of the nature of the force. (9-12)
• Unbalanced forces will cause changes in the speed or direction of an object's motion. (Acceleration) (5-8)
• The motion of an object can be described by its position, direction of motion, and speed. (5-8)
• Process Standards for Professional Development
• Research-Based
• Address teachers' needs as learners and build on their current knowledge of science content, teaching, and learning. (NSES)
• Design
• Introduce teachers to scientific literature, media, and technological resources that expand their science knowledge and their ability to access further knowledge. (NSES)
• Learning
• Build on the teacher's current science understanding, ability, and attitudes. (NSES)

##### Customer Reviews
 Loved the interactives Reviewed by: Wendy Ruchti (Pocatello, ID) on March 14, 2013 This science object was well-done. I enjoyed the walk through, and even though this was a review for me, I think it helps educators thing about the progression of their own lessons in teaching these concepts. I never know where to start when teaching forces, but realized that of course you start with position, speed, velocity, etc. just as the science object did.

 Good Job Describing Concepts Reviewed by: Jennifer M Tanko on October 22, 2012 This science object did a very good job making the concepts more concrete and relatable. Some of the questions are difficult but that helps you work through it and learn!

 so so discussion Reviewed by: Kelly (Los Ranchos de Albuquerque, NM) on July 20, 2012 This tutorial was interest, but a little shy on clarity when it came to more complex concepts. The secion in which it discussed average velocity versus instantaneously velocity, was not clearly defined. Examples could have been very helpful to illustrate this.

 Very Helpful Reviewed by: Tracey Williams on July 17, 2012 Helped me identify my own misunderstandings.

 Questions were tough Reviewed by: Brandy Stewart on December 30, 2011 This was a very informative object. The questions were difficult to follow, and some of the animations were confusing. If you took all that out and look at the information presented to you, and especially if you are familiar with the information already, it gives you a lot of ideas to use in the classroom.

 Position and Motion Reviewed by: Hubert Hill (Dallas, TX) on October 9, 2011 Way too technical!

 Review Force and Motion Reviewed by: Jean O (Jersey City, NJ) on April 30, 2010 This was really very difficult for me to understand. The videos was very helpful but I did find the concept something I would not be comfortable teaching to the students. I really would have to put a lot of time building my own knowledge about this topic.

 Position and motion Reviewed by: Marilyn Ortiz (Jersey City, NJ) on April 3, 2010 The tutorial has many self-checking questions and interactive video clips. I did enjoy the hare and tortoise video clip because it’s a story many students have heard and know that the tortoise wins the race because he had a steady pace throughout the race. The hands-on activity about rolling a ball across a smooth surface is an activity I will conduct in my classroom. I learned that when you specify the velocity of an object you must specify not only the speed but on which direction it is traveling.

 Fun! Reviewed by: Liz M (Interlaken, NY) on August 8, 2009 This one was kind of fun! I wish the sequence of these SO's was more obvious since it seems to help to do them in order. Some really good foundational knowledge for me to be aware of as I move forward. Good source of information!
