Physical Science

S5P1. Obtain, evaluate, and communicate information to explain the differences between a physical change and a chemical change.

 

a. Plan and carry out investigations of physical changes by manipulating, separating and mixing dry and liquid materials.

 

b. Construct an argument based on observations to support a claim that the physical changes in the state of water are due to temperature changes, which cause small particles that cannot be seen to move differently.

 

c. Plan and carry out an investigation to determine if a chemical change occurred based on observable evidence (color, gas, temperature change, odor, new substance produced).

 

S5P2. Obtain, evaluate, and communicate information to investigate electricity. a. Obtain and combine information from multiple sources to explain the difference between naturally occurring electricity (static) and human-harnessed electricity.

 

b. Design a complete, simple electric circuit, and explain all necessary components.

 

c. Plan and carry out investigations on common materials to determine if they are insulators or conductors of electricity.

 

S5P3. Obtain, evaluate, and communicate information about magnetism and its relationship to electricity.

a. Construct an argument based on experimental evidence to communicate the differences in function and purpose of an electromagnet and a magnet. (Clarification statement: Function is limited to understanding temporary and permanent magnetism.)

 

b. Plan and carry out an investigation to observe the interaction between a magnetic field and a magnetic object. (Clarification statement: The interaction should include placing materials of various types (wood, paper, glass, metal, and rocks) and thickness between the magnet and the magnetic object.)
