Jane and Tara went to the beach. It was hot. The sun was out. The sky was clear. Jane put on some sunscreen. She put it on her arms, legs, and face. She did not want her skin to burn. Her sunscreen was SPF 50. That means Jane can stay in the sun 50 times longer than she could without it.
With SPF 50, Jane probably will not get sunburnt. She asked Tara if she needed any. "No, I'm okay," Tara replied. Jane warned her that she would get burnt. Tara ignored her. When they went back home, Tara just got tanner. She didn't get burnt. Some people don't burn.
