The apostrophe is generally used to show possession or a contraction. Example 1: "Melissa broke her brother'sskateboard." In this sentence we can see that the apostrophe is used to tell us that the skateboard Melissa broke belongs to her brother. Hence, the apostrophe is used to show possession. Example 2: "Melissa thinks that her brother's a jerk." In this sentence we can see that the apostrophe is used to contract or shorten "brother is." Hence, the apostrophe is used to show a contraction. Other, more common contractions, such as "isn't" (is not) and "don't" (do not) are formed similarly. The best way to decide the proper use of an apostrophe is to know what it is you are writing about. Ask yourself, "Am I writing about a thing that belongs to someone, or am I trying to shorten two words into one?"
