This free comprehension activity allows students to compare and contrast explorers from three eras: Ponce de Leon, Lewis and Clark, and the Apollo 11 astronauts. It's primarily designed to accompany the three read aloud plays Ponce de Leon and the Fountain of Youth, Lewis and Clark and Bird Girl, and Fly Me to the Moon (all available on my TpT store), but it can also be used independently as a research guide. Teachers can further extend the activities by using the same format to compare other explorers. Two compare and contrast activities are included (basic and advanced) and both come with answer keys. Thanks!
