Space Coast Vocabulary Adventure

Read the story closely. Use details from the text to explain your thinking, and use the vocabulary words accurately.

The Case of the Missing Star Cookies

On launch day, the cafeteria had prepared a batch of star-shaped cookies to celebrate. When the students arrived for lunch, the serving tray was empty. “That is preposterous,” said Chloe, peering at the crumbs. “The tray was full just a few minutes ago.” Lucy scrutinized the counter, looking closely for clues. Beside the tray, he spotted a trail of blue frosting that led toward the kitchen door. “I hypothesize that whoever took the cookies left this behind,” he said. Chloe and Lucy collaborated, asking the kitchen staff what they had seen. They learned that a cart had rolled past the counter on its way to the teachers’ meeting room. After an exhaustive search, the pair found the cookies there, safe and untouched. A staff member had moved them by mistake. The mystery was solved before the rocket launch began.
