Structures
Paper folded into a concertina is strong.

Structures

Learn how structures are built to stay standing. Explore strength, stability, and smart shapes like triangles, then practise improving designs so they can hold weight without tipping or bending.

Fascinating Fact:

Structures need to be strong so they do not break. They also need to be stable so they do not tip over.

In KS2 D and T, structures are frameworks built to support weight and stay in shape. You learn how materials, joints, and shapes affect strength, and how design choices like a wide base, bracing, or triangular frames can improve stability.

  • Structure: Something built from parts that work together to support a load, such as a bridge, tower, or frame.
  • Stability: How well a structure stays upright without tipping, especially when weight is added.
  • Bracing: Extra supports added to stop a structure from wobbling, bending, or collapsing.
What is a structure in KS2 design and technology?

A structure in KS2 D and T is a built framework or shape that supports weight and holds its form, like a bridge, shelter, chair, or tower.

How do you make a structure stronger and more stable?

You can improve strength and stability by using strong materials, making secure joints, adding bracing, using triangles, and designing a wider base so the structure is less likely to tip.

Why are triangles used in bridges and towers?

Triangles are used because they are a rigid shape that spreads forces through the frame. This helps structures resist bending and keep their shape when loads are added.

1 .
Which frame is the strongest?
Triangle
Square
Rectangle
Hexagon
The triangle is the strongest frame
2 .
What do all structures need?
A framework
Legs
Nets
Glue
A framework is what supports a structure
3 .
Which paper will be strongest?
A flat sheet of paper
A sheet of paper folded in half
A sheet of wet paper
A sheet of paper folded into a concertina
Have you ever made a paper fan? They are much stronger than unfolded paper
4 .
Which is the best method of joining textile and wood?
Welding
Sticky tape
Metal tacks
Needle and thread
Metal tacks can be hammered through the material and into the wood
5 .
Which of these is NOT used to join paper?
Glue
Sticky tape
Paper clips
Metal solder
Solder is used to join metal together, for example metal wires in electronics
6 .
How could a square wooden frame be made sturdier?
Use cardboard triangles on the corners
Use strong nails
Paint the corners
Add a dab of glue to each corner
The triangles add their own strength to support the corners
7 .
What is the minimum number of legs required for a chair to stand up?
1 leg
2 legs
3 legs
4 legs
One-legged and two-legged chairs are unable to balance
8 .
In order to be stable a structure must what?
It must be strong
It must balance
It must have five legs
It must be made of metal
Some weak structures can stand up, if they are not disturbed. Think of a house of cards
9 .
What is the flat shape that can be folded to make a box called?
Web
Net
Cube
Package
A net has six squares joined together. When it's folded these squares become the faces of the cube
10 .
What is the purpose of a structure?
To protect objects
To support a load
For climbing on
To be fun
All structures have to support a load, even if it is just their own weight
