SOLs & Curriculum Framework
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.
Understanding the Standard (Background Information for Instructor Use Only)
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.
Essential Knowledge, Skills, and Processes
In order to meet this standard, it is expected that students will
make and communicate observations about moving objects. Examples should include balls, objects with wheels, windup toys, tops, rubber bands, and playground equipment.
predict an object’s movement, using its size, shape, and the force of the push or pull on it.
manipulate objects in order to describe and classify the motion of each object as straight, circular, or back-and-forth.
understand that vibrations may create sound, such as humming, strumming a guitar, or plucking a rubber band.
record observations of movement (length/distance), using nonstandard units.

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
Understanding the Standard (Background Information for Instructor Use Only)
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 not.
The temperature of the water affects how easily a substance will dissolve in it.
Essential Knowledge, Skills, and Processes
In order to meet this standard, it is expected that students will
describe and apply the term dissolve.
predict and describe how various materials (vinegar, milk, baking soda, powdered drink mix, sugar, salt, sand, oil, soil, rocks) act when mixed with water.
classify liquids and solids into those that will dissolve in water and those that will not. Use tables and/or charts to record and display the information.
infer that some substances will dissolve more easily in hot water than in cold water by conducting investigations using water at different temperatures.
