Grade Two

Physical Sciences

Students demonstrate an understanding of the composition of physical systems and the concepts and principles that describe and predict physical interactions and events in the natural world. This includes demonstrating an understanding of the structure and properties of matter, the properties of materials and objects, chemical reactions and the conservation of matter. In addition, it includes understanding the nature, transfer and conservation of energy; motion and the forces affecting motion; and the nature of waves and interactions of matter and energy. Students demonstrate an understanding of the historical perspectives, scientific approaches and emerging scientific issues associated with the physical sciences.

Benchmark B: [K-2] Forces and Motion
Recognize that light, sound and objects move in different ways.



Benchmark C: [K-2] Forces and MotionExplore that objects move in different ways.



Indicators
Forces and Motion 1. Explore how things make sound (e.g., rubber bands, tuning fork and strings).

2. Explore and describe sounds (e.g., high, low, soft and loud) produced by vibrating objects.

3. Explore with flashlights and shadows that light travels in a straight line until it strikes an object.
