🔗 Part 1: Matching — Bridge Types

Draw a line to match each bridge type with its correct description.

Beam Bridge

Truss Bridge

Arch Bridge

Tension

Compression

A curved structure that pushes forces outward and downward

A pulling force that stretches a material

The simplest bridge — a flat surface supported at each end

A pushing force that squeezes a material together

A bridge made of triangles joined together for strength

✏️ Part 2: Fill in the Blanks

Use the word bank below to complete each sentence.

1. The simplest type of bridge is a _________________ bridge, which is just a flat surface placed across a gap.

2. A _________________ bridge uses triangles to spread the weight of the bridge evenly.

3. The Sydney Harbour Bridge is an example of an _________________ bridge.

4. A force that pushes and squeezes materials together is called _________________.

5. A force that pulls and stretches materials apart is called _________________.

8. In the box below, draw a simple truss bridge. Label the following parts: deck (road surface), triangles, supports. Add an arrow to show where the load pushes down.

9. During the bridge-building activity, which type of bridge did your group make? Tick all that apply:

Beam Bridge

Truss Bridge

Arch Bridge

A mix of more than one type

10. Write one thing your group did well during the bridge-building activity, and one thing you would change if you built it again.

We did well at:
