This Grade 3 hard-1 worksheet challenges students to compare fossils with modern organisms and identify extinct species. Grade 3 learners answer four multiple-choice questions about fossil types, past environments, and extinct animals such as the woolly mammoth. Five fill-in-the-blank items use words like extinct, modern, related, and past to help Grade 3 students build careful arguments from fossil evidence about how life on Earth has changed today.
Style:
Fossils and Evidence of Past Life
