OVERALL EXPECTATIONS
- assess the importance of form, function, strength, and stability in structures through time;
- investigate strong and stable structures to determine how their design and materials enable them to perform their load-bearing function;
- demonstrate an understanding of the concepts of structure, strength, and stability and the factors that affect them.

KEY VOCABULARY/DEFINITIONS
A structure is something with a definite size, shape, purpose, and can hold a load.
A material is something that is used to make an object or structure. Most structures are made of many materials.
The strength of a structure is its ability to support a load. Humans have invented different ways of making materials and structures stronger (E.g., twisting/braiding, adding layers, folding, etc.)
The stability of a structure is its ability to balance and stay fixed in one spot.
Durable means a material or structure will not get damaged easily.
Flexible means a material or structure can bend without breaking.
Triangulation means using a triangle shape to make a structure stronger and more stable.
A force is a push or a pull. A force can affect the shape, balance, or position of a structure.
Compression is a force where something is squished down or pushed together
Tension is a force where something is pulled apart or stretched.
A strut is a rod or bar that helps a structure resist pressure. A tent pole is a strut.
A tie is a beam or wire that supports a structure with tension. A tent cord is a tie.

ADJECTIVES are describing words! They should be used to full express the characteristics of the materials we encounter in this unit. Remember to use all of your senses when experiencing a material.
NATURAL VS. HUMAN MADE/BUILT STRUCTURES/MATERIALS
Natural materials/structures can be found in nature (e.g. a spider web)
Human-made/Built materials/structures: Natural material + tools + skill = human made
A person that designs structures is called an architect.
Every structure has a size, shape, and purpose!

STRENGTH IN ACTION
The strength of a structure is its ability to support a load. Humans have invented different ways of making materials and structures stronger (E.g., twisting/braiding, adding layers, folding, etc.)
A weapon made of toilet paper!
WHAT MAKES A BRIDGE STRONG?:
Beam vs. Truss (The use of triangles spreads out the weight of the load) vs. Suspension
