Compression is when things press together
Tension is when things get stretched or pulled out from each other
Next week we will compare the strength of a suspension bridge to a beam bridge.

Compression and Tension
Today we started to make suspension bridges. We learned about
Compression and Tension.
Compression is when things press together
Tension is when things get stretched or pulled out from each other
We made our bridges out of straws and string. Sellotape to stick them to chairs, and some marbles done up in some tissues for our weight.
Next week we will compare the strength of a suspension bridge to a beam bridge.
