S5P1 Students will verify that an object is the sum of its parts. 
a. Demonstrate that the mass of an object is equal to the sum of its parts by manipulating and measuring different objects made of various parts.
b. Investigate how common items have parts that are too small to be seen without magnification.  
S5P2 Students will explain the difference between a physical change and a chemical change.
a. Investigate physical changes by separating mixtures and manipulating (cutting, tearing, folding) paper to demonstrate examples of physical change. 
b. Recognize that the changes in state of water (water vapor/steam, liquid, ice) are due to temperature differences and are examples of physical change. 
c. Investigate the properties of a substance before, during, and after a chemical reaction to find evidence of change. 
S5P3 Students will investigate the electricity, magnetism and their relationship. 
a. Investigate static electricity. 
b. Determine the necessary components for completing an electric circuit. 
c. Investigate common materials to determine if they are insulators or conductors of electricity. 
d. Compare a bar magnet to an electromagnet. 

Physical Science is my favorite science unit of 5th grade. One of the reasons for this is because there are so many experiments that go along with these standards. You can take a look at the standards to the left and then follow the link to see videos and other information about each standard.
