First Grade Science | Unit 4 | Animal Body Parts

Turn animal questions into a month of observing, testing, and building. Help first graders discover how shells, quills, webbed feet, fins, beaks, and trunks help animals—and use those discoveries to design something useful.

This 74-page, four-week Wonder Detectives Academy unit includes 12 guided lessons and five reusable science centers, organized for three lessons per week.

Students begin by noticing animal parts and explaining their jobs. They compare tools as models, investigate useful features versus decoration, and finish by building, testing, and improving a shell-inspired protective cover.

Your unit includes:

• 12 lesson guides with learning targets, materials, timed teaching steps, and linked models.
• Five complete centers with printed resources and directions for matching, sorting, comparing tools, exploring design ideas, and building.
• Animal observation cards, feature close-ups, biological clues, and matching mats.
• Teacher think-alouds, realistic classroom visuals, and Fox and Owl science stories.
• Clear investigation setups, reusable evidence records, and student planning pages.
• Answer guides, starting and final checks, a science-thinking rubric, and class records.
• Clickable navigation and a print guide to help you find and prepare resources quickly.

Children can demonstrate understanding through pointing, discussion, drawing, writing, and their physical models. Project the color resources and print only the materials you need, including economical black-and-white planning and recording pages.

The animal-inspired material-design challenge supports NGSS 1-LS1-1 by connecting an animal part’s useful function to a human problem.
