Teach students how animal structures support survival, growth, behavior, and reproduction with this Animal Structures & Adaptations Unit aligned to NGSS 4-LS1-1.

Designed for upper elementary science, this engaging unit helps students understand the structure and function of animal body parts through hands-on activities, reading, and scientific modeling. Perfect for grades 3-5.

Students explore how animals use internal and external structures for nutrition, protection, movement, communication, and reproduction. This unit includes opportunities for collaboration, discussion, writing, and STEM challenges — great for science centers or whole-group instruction.

✨ What’s Included:

• Activity 1: Animal Structures Sort – Students identify animal structures and predict their functions
• Activity 2: My Beak Is Better Than Yours – Hands-on beak experiment to explore feeding adaptations
• Activity 3: Salmon Swim Home – Students act as salmon and use their sense of smell to navigate home
• Activity 4: What Is Biomimicry? – Informational reading passage with comprehension questions
