Standard(s): 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).
