A. Mechanics
|
1. Cite evidence from observations to describe the motion of an object using position and speed.
|
a. Describe the position of an object by locating it relative to another object or to its background.
|
b. Using information from multiple trials, compare the speeds (faster or slower) of objects that travel the same distance in different amounts of time.
|
c. Using information from multiple trials, compare the distances that objects moving at different speeds travel in the same amount of time.
|
2. Explain that changes in the ways objects move are caused by forces.
|
a. Observe and describe the way an object's motion changes in a variety of situations (rolling a ball, bouncing a ball, dropping a yo-yo, winding up a toy, etc.) and identify what may have caused the change.
|
b. Describe changes in the motion of objects as they move across different textured surfaces and suggest possible causes for the change.
|
c. Observe and describe that objects fall to the ground unless something holds them up (gravity).
|
|
B. Thermodynamics
|
1. Recognize and describe that heat is transferred between objects that are at different temperatures.
|
a. Recognize and describe that the temperature of an object increases when heat is added and decreases when heat is removed.
|
b. Recognize and describe that heat will flow between object at different temperatures until they reach the same temperature.
|
|
C. Electricity and Magnetism
|
|
D. Wave Interactions
|
2. Identify and describe the relationship between a sound and the vibrations that produce it.
|
a. Based on observations of objects that produce sound, relate vibration to the back and forth motion of parts of the object.
|
b. Pose questions concerning the relationship between loudness or pitch and the vibration of an object.
