Force, Motion, and Energy
1.2 The student will investigate and understand that moving objects exhibit different kinds of motion. Key concepts include"
a) objects may have straight, circular, and back-and-forth motions;
b) objects may vibrate and produce sound; and
c) pushes or pulls can change the movement of an object.
Matter
1.3 The student will investigate and understand how different common materials interact with water. Key concepts include:
a) some liquids will separate when mixed with water, but others will not;
b) some solids will dissolve in water, but others will not; and
c) some substances will dissolve more readily in hot water than in cold water.

Background
1.2
1.3
- An object’s motion may be described by tracing and measuring its position over time. The motion of objects may be straight, circular, curved, or back-and-forth.
- One kind of back-and-forth motion is vibration. Vibrations may create sound.
- Pushing or pulling can change the position and motion of objects. For the same object, the size of the change is related to the strength of the push or pull.
1.3
- Different types of materials act differently when mixed with water.
- Some liquids will mix with water, while others will not.
- Some solids will dissolve in water, while others will notThe temperature of the water affects how easily a substance will dissolve in it.
