Background Information

__1.) Important Vocabulary- Ashley Webb__ There are some vocabulary words that are used in the AIMS activity on Roller Coasters and the Picture Perfect activity Sheep In A Jeep that have to do with motion and force. These words are words that the students will need to know to gain a better understanding of the concept being explored. They are listed below under the activity they are involved in.

"Coaster Construction" and "Ball On A Roll" -Kinetic Energy- the energy an object has because it is moving -Potential Energy- energy an object has because of its position or shape
 * AIMS Activities**

"Rally Round the Room" -Engineer- a person that applies mathematics and science to the design and construction of real objects and mechanisms -Inclined Plane- a flat piece of material that makes an angle with a horizontal surface -Motion- the continuous change of position Kinetic and Potential Energy as well

"Bounce Back" -Gravitational Potential Energy- energy an object possesses because of its height relative to a reference level -Kinetic Energy also.

"Wind Rollers" -Kinetic Energy

"Slip, Sliding Away" -Friction- a force, a resistance to motion

-Motion- the continuous change of position -Force- a push or pull -Friction- a force, a resistance to motion -Gravity- force that pulls everything down -Air Resistance- friction with the air, slows motion of objects -Inertia- Newton's First Law

 * All of the vocabulary words and definitions came from the activities.**

Sheep In A Jeep Activity from Picture Perfect: #66 Traffic Light Cups AIMS Activities: Slip, Sliding Away:#27 I Think-We Think Wind Rollers: # 32 K-W-L Bounce Back: #21 Friendly Talk Probes (use to probe from the book on gravity on pg. 103) Rally Round the Room: #31 Justified True or False Statements Coaster Construction: #1 A&D Statements Ball on a Roll: #28 I Used To Think...But Now I Know

__3.) Misconceptions/Mistakes students make- Toni__
 * If an object is at rest, no forces are acting on the object
 * That force is a property of an object. An object has force and when it runs out of force it stops moving.
 * Large objects exert a greater force than small objects.
 * Acceleration is confused with speed.
 * Motion/velocity implies force.
 * The terms "energy" and :force" are interchangeable.
 * If an object is at rest, then it has no energy.
 * Gravitational potential energy depends only on the height of an object.
 * If we double the speed of a moving object, then we double the kinetic energy as well.
 * That things use up energy.
 * They are less likely to see passive forces. They believe that more force is needed to put an object into motion than to stop it.
 * In respect to gravity, that heavier objects fall faster than lighter objects.

//Further in-depth explanations of misconceptions can be found at the beginning of each activity's lesson plan.//
__4.) Basic Facts/Laws Covered- Samantha__ Facts on Motion: //The 3 Laws of Motion- Created by Isaac Newton//
 * “The first law says that an object at **rest ** tends to stay at rest, and an object in **motion ** tends to stay in motion, with the same direction and speed .”
 * The tendency to follow this law is called //inertia.//


 * “The second law says that the acceleration of an object produced by a net (total) applied force is directly related to the **magnitude ** of the force, the same direction as the force, and inversely related to the mass of the object.”


 * “The third law says that for every action (force) there is an equal and opposite reaction (force).”

Remind students that like all good scientists, experiments should be tested more than once.
