Standard 5.2.2.1

An object's motion is affected by forces and can be described by the object's speed and the direction it is moving.

Benchmark: 5.2.2.1.1 Simple Machines

Give examples of simple machines and demonstrate how they change the input and output of forces and motion.

Benchmark: 5.2.2.1.2 Force & Changing Motion

Identify the force that starts something moving or changes its speed or direction of motion.

For example: Friction slows down a moving skateboard.

Benchmark: 5.2.2.1.3 Relating Force to Motion Changes

Demonstrate that a greater force on an object can produce a greater change in motion.

## Overview

Standard in Lay Terms

MN Standard in Lay Terms

Motion is when an object's position is changed.  This change is measured as distance traveled per time.  Change in position of an object cannot happen without applying a force.  The force upon the object can be measured by speed or direction.  The amount of force is determined by the change  in speed, direction an object.

Big Ideas and Essential Understandings

Big Idea

The motion of an object can be described by its position, direction of  motion, and speed. Motion can be measured and represented on a graph.

An object that is not being subjected to a force will continue to move at a constant speed and in a straight line.

If more than one force acts on an object along a straight line, then the forces will reinforce or cancel one another, depending on their direction and magnitude.

The Essentials

To any action there is always an opposite and equal reaction; in other words, the actions of two bodies upon each other are always equal and always opposite in direction.

Correlations
• NSES Standards:

The motion of an object can be described by its position, direction of motion, and speed. That motion can be measured and represented on a graph.  An object that is not being subjected to a force will continue to move at a constant speed and in a straight line.   If more than one force acts on an object along a straight line, then the forces will reinforce or cancel one another, depending on their direction and magnitude. Unbalanced forces will cause changes in the speed or direction of an object's motion. (NSES, 1996)

By the end of 5th grade students should know that:

1.    Changes in speed or direction of motion are caused by forces.

2.    How fast things move differs greatly.

Benchmarks of Science Literacy

By the end of the 5th grade, students should know that

Changes in speed or direction of motion are caused by forces. 4F/E1a

The greater the force is, the greater the change in motion will be. The more massive an object is, the less effect a given force will have. 4F/E1bc

How fast things move differs greatly. Some things are so slow that their journey takes a long time; others move too fast for people to even see them. 4F/E2

Common Core Standards

Language Arts Standards:

## Misconceptions

Student Misconceptions

Student Misconceptions about Forces and Motion

A list compiled by the Operation Physics Elementary/middleschool physics education outreach project of the American Institute of Physics. Author/editor is unknown.

1.      The only "natural" motion is for an object to be at rest.

2.      If an object is at rest, no forces are acting on the object.

3.      Only moving objects can exert a force.  If an object is at rest on a table, there are no forces are acting upon it.

4.      Force is a property of an object.  An object has force and when it runs out of force it stops moving.

5.      The motion of an object is always in the direction of the net force applied to the object.

6.      Large objects exert a greater force than small objects.

7.      A force is needed to keep an object moving with a constant speed.

8.      Friction always hinders motion.  Thus, you always want to eliminate friction.

## Vignette

The students gather in their groups to brainstorm the possible tools that could help them lift Mr. C. off the ground.  The obvious ones come up: use a crane (lots of laughs), an elevator, etc.  Mr. C. then asks them what could they do if they had no access to mechanics and today's technology?  Most of the students are stumped.  So, Mr. C.  introduces a large plank and a block of wood.  "Now, how could you use these simple tools to lift Mr. C.?"  The students come up with the idea of using it as a lever by putting the block of wood under the plank and placing Mr. C. on one end of the plank and another student at the other end.  Mr. C. asks "Where are you going to place the block of wood and who would be the person?"  Groups quickly come up with the idea of placing the block in the center under the plank, and that Jason should be the one to stand on the other end since he is the largest of the students.  Mr. C. then stands on one end of the plank and Jason stands on the other end.  The class is riveted with anticipation that Jason will be able to lift Mr. C.  They soon find out, as Jason stands on his end, that he cannot (another big laugh).  Mr. C. asks the groups to come up with a reason why this did not work and what they could do make it work.  Most groups come back with the idea of moving the block of wood.  Some say closer to Mr. C. and others say further away from the center.  At this time, Mr. C. poses another challenge: instead of Jason lifting Mr. C., Tess (the smallest girl) would have to lift Mr. C.  After a number of trials and moving the block of wood to various places under the plank, Tess is able to lift Mr. C, and she gets a rousing applause.

At this point, Mr. C. introduces the concept of  a lever and its ability to lift a load.  Mr. C. draws a diagram on the board and labels the parts of this simple machine.  He tells the class that the parts of this simple machine are the lever arm (plank), the fulcrum ( the block of wood), the effort (Tess standing on one end), and the motion or lift (Mr. C. off the ground).

Mr. C. then asks the class to go back to the other question that they are to try to answer (from group 3): "What is preventing us from lifting Mr. C. off the ground?"  The students make a list of possibilities in their notebooks and after some discussion, it is determined that gravity plays a part and mass has something to do with it as well.  Mr. C. then introduces that force is need to make the load (Mr. C.) move or lift, and that the greater the force results in a greater motion or lift.  In a following lesson, Mr. C. has them explore how changing the fulcrum can change the amount of force needed to move a load like Mr. C.

Instructional suggestions/options

This standard is best understood if one (the teacher) really understands Newton's three laws of motion, (students aren't expected to know them) no matter what words one uses to articulate them, then much of the ways things move become clear. It is imperative that the student be led to observe and to analyze the way things actually move. The "Laws" of motion are laws only in the sense that they are rules that describe what actually is happening when an object moves. Isaac Newton, about three hundred and twenty years ago (1687), was able to summarize all the essential knowledge of motion in three fundamental rules: Newton's Laws of Motion.

Assessment Vignette:

Class is studying the motion of objects. One student, describing his idea about motion and forces, points to a book on the desk and says "right now the book is not moving." A second student interrupts, "Oh, yes it is. The book is on the desk, the desk is on the floor, the floor is a part of the building, the building is sitting on the Earth, the Earth is rotating on its axis and revolving around the Sun, and the whole solar system is moving through the Milky Way." The second student sits back with a self-satisfied smile on her face. All discussion ceases.

The ability to reason scientifically.

The ability to use science to make personal decisions and to take positions on societal issues.

The ability to communicate effectively about science.

This assessment standard highlights the complexity of the content standards while addressing the importance of collecting data on all aspects of student science achievement. Educational measurement theory and practice have been well developed primarily to measure student knowledge about subject matter; therefore, many educators and policy analysts have more confidence in instruments designed to measure a student's command of information about science than in instruments designed to measure students' understanding of the natural world or their ability to inquire. Many current science achievement tests measure "inert" knowledge-discrete, isolated bits of knowledge-rather than "active" knowledge-knowledge that is rich and well-structured. Assessment processes that include all outcomes for student achievement must probe the extent and organization of a student's knowledge. Rather than checking whether students have memorized certain items of information, assessments need to probe for students' understanding, reasoning, and the utilization of knowledge. Assessment and learning are so closely related that if all the outcomes are not assessed, teachers and students likely will redefine their expectations for learning science only to the outcomes that are assessed.

Learn a variety of techniques to help your special education students overcome challenges to enjoy success in science.

Overcoming Obstacles to Success in the Science Classroom

What specific techniques benefit special education students in the science classroom? Strategies designed to increase classroom success for special education students are based on sound instructional methodology, and thus have potential benefits for all students. When integrating the strategies suggested below, teachers must remember that the term "special education" is applied to students having a wide range of disabilities existing on a continuum from moderate to extreme. Instructors should consider individual needs and learning preferences when implementing strategies.

Dealing with Issues Related to Attention

Split up large chunks of instruction, particularly experimental procedures, into small parts. Have students repeat directions in their own words. Integrate hands-on instruction with traditional methods. Switching to a different instructional modality can re- focus wandering attention.

Use laboratory time for one-on-one instruction. Speaking with a student individually is a powerful tool for focusing attention. Find ways to integrate topics interesting to students. Encourage expression of opinion and discussion. Consider seating arrangements. There is no "right" seat for a student with a given disability. A student with difficulty focusing may experience increased success if seated away from high-traffic areas.

Incorporate body posture changes. Sitting straight up in a chair might not prove the most effective learning posture, particularly for students with Attention Deficit Disorder.

Dealing with Issues Related to Information Processing and Communication

Communicate information in multiple formats. Students may process information more effectively in an oral, visual, or kinesthetic framework. Write lab procedures in large, legible print. The blackboard or other communication medium should not be cluttered with irrelevant information.

Coincide verbal directions with demonstration whenever possible. Procedures such as lighting a burner and using a balance must be demonstrated and practiced for mastery. Clearly label laboratory equipment. Color coding materials may enhance identification. Develop cue cards which outline, in written or pictorial form, major procedural steps. Prominently display cards in sequential order.

Utilize multiple assessment tools. Students with disabilities may communicate understanding effectively through presentations, demonstrations, lab work, and the creation of portfolios.

Dealing with Issues Related to Organization

Maintain a clean, organized laboratory. Clutter is an additional obstacle for students already struggling with organization. Maintain consistent places in the lab for supplies and equipment. Clearly label these stations. Establish and constantly reinforce techniques for often-used procedures, such as cleaning and returning lab materials, using goggles, and using specific lab equipment.

Note to Teachers, Parents, and other adults using this site: Please read this important information before continuing to surf this Web site with your children and students.

Dealing with Issues Related to Social Interaction

Create a climate of acceptance by modeling patience and tolerance. Students must feel comfortable asking questions and expressing opinions in the science classroom. Build laboratory and cooperative learning groups carefully. Students with disabilities must be grouped with students who will allow them to participate and use their strengths, but who are also willing to cooperate with their areas of difficulty.

Dealing with Issues Related to Time and Making Transitions

Provide an initial orientation to laboratory organization, equipment, and procedures. Make this instruction ongoing throughout the year, ensuring understanding of existing structures, and incorporating new techniques and equipment as needed. Make students aware of time limits before and during laboratory exercises and small group work.

Warn students a few minutes before the scheduled ending of an activity. This eases transition from one activity to another, and forces the group to come to closure.
