|
2.5(G)
Describe how factors or conditions can cause objects, organisms, and systems to either change or stay the same. |
|
2.6(A)
Classify matter by observable physical properties, including texture, flexibility, and relative temperature, and identify whether a material is a solid or liquid. |
|
2.6(B)
Conduct a descriptive investigation to explain how physical properties can be changed through processes such as cutting, folding, sanding, melting, or freezing. |
|
2.6(C)
Demonstrate that small units such as building blocks can be combined or reassembled to form new objects for different purposes. |
|
2.7(A)
Explain how objects push on each other and may change shape when they touch or collide. |
|
2.7(B)
Plan and conduct a descriptive investigation to demonstrate how the strength of a push and pull changes an object's motion. |
|
2.8(A)
Demonstrate and explain that sound is made by vibrating matter and that vibrations can be caused by a variety of means. |
|
2.8(B)
Explain how different levels of sound are used in everyday life such as a whisper in a classroom or a fire alarm. |
|
2.8(C)
Design and build a device using tools and materials that uses sound to solve the problem of communicating over a distance. |
|
2.9(A)
Describe the Sun as a star that provides light and heat and explain that the Moon reflects the Sun's light. |
|
2.9(B)
Observe objects in the sky using tools such as a telescope and compare how objects in the sky appear different with a tool than with an unaided eye. |
