Universal Concept #5: Structure
A structure is how the parts of something are arranged and connected. Skyscrapers, bird beaks, spider webs, your skeleton, and even a paragraph all have a structure. The big secret: the way something is built helps it do its job!
🧱 Parts
The pieces something is made of.
📐 Arrangement
How the parts are put together, in what shape and order.
💪 Strength
Some shapes hold up weight better than others.
🎯 Function
The job the structure does.

Paper Strength Lab
Same paper. Different shapes. How many books can each one hold?
🤔 1. Predict first!
Every shape is made from ONE sheet of paper. Which shape do you think will hold the MOST books?
🧪 2. Test each shape
Tap a shape to test it. Test all six!
🧑🔬 These results are like a typical classroom test. Try it for real with paper, tape, and a stack of books! Your numbers might be different, and that's what real scientists expect.

Arches: The 2,000-Year-Old Trick
Ancient Romans built arches that are STILL standing today.
An arch is made of wedge-shaped stones. Builders put them on a wooden frame, starting at the bottom on both sides. The last stone at the very top is the keystone. It locks everything together!
