Free sample focus: Use spoon, tweezer, and clothespin “beaks” to discover how structure changes what a tool can pick up.
Showcase sample
Use spoon, tweezer, and clothespin “beaks” to discover how structure changes what a tool can pick up.
Animal body parts have shapes that help them do jobs, and engineers can copy helpful structures.
📋 NGSS Alignment: 1-LS1-1 — Use materials to design a solution to a human problem by mimicking how plants or animals use external parts.
🎯 Learning Objective
Students will compare simple “beak tools” and use evidence to explain how structure helps animals get food.
💡 The Big Idea
Animal body parts have shapes that help them do jobs, and engineers can copy helpful structures.
Beak shape helps the job
The tool-test visual keeps the science concrete: each beak shape is matched to the kind of food job it does best.
Compare beak-like tools
Match shape to food job
Explain which structure helped

🧪 Investigation
Step 1 — Meet the challenge A bird needs to pick up different foods: seeds, worms, and nectar models.
Step 2 — Choose tools Use spoon, tweezers, and straw/chopsticks as pretend beaks.
Step 3 — Test one food Try picking up round paper “seeds” with each tool.
Step 4 — Test another food Try string “worms” or water drops/beans with the tools.
Step 5 — Compare structure and job Circle which tool worked best for each food.
Step 6 — Engineer connection Students design a pretend tool inspired by the best beak.

🚀 Extension
Try this next: Ask your child to repeat one part of the test tomorrow or with one changed material, then explain what stayed the same and what changed.
👩🏫 Parent/Teacher Notes
At-home win: This free sample is complete enough to teach today and polished enough to show how a full Little Lab Coats lesson feels.
Evidence move: Press students to point to a mark, drawing, comparison, or observation before they explain.
Family-friendly pacing: If attention is short, do steps 1–4 today and the worksheet discussion later.
