The day of the school science fair had finally arrived, and Lisa was both nervous and excited. She couldn't wait to show off her volcano model at the fair. She might even win the first prize!
As Lisa was setting up her volcano, she noticed her friend Alex's project on the table next to hers. Weeks ago, Alex had asked her for help in creating a model of the solar system, and Lisa was glad to help. He never told her he as going to enter it in the Science Fair! His model was painted beautifully in different colours. Finally Alex got the first place and Lisa felt very embarrassed.
