What Makes a Structure Strong
A structure is something we build, like a tower, a house or a bridge. A good structure is strong and stable, so it does not fall down.
- A wide base at the bottom helps a structure stand steady.
- A tall, thin tower falls over easily.
- Strong shapes like the triangle make a structure stronger.
Key idea
A wide base and strong shapes make a structure strong and stable.
Building It Well
When we build with blocks, we put big, heavy blocks at the bottom and lighter ones on top. This keeps the tower from falling.
Remember
- A wide base makes a structure steady.
- Put heavy blocks at the bottom.
- Triangles are strong shapes.
