• part of a structure made of beams arranged in a special pattern

• a beam

• wooden struts

What is the first phase in building a structure?

What do we call people who design structures?

• architects

• amazing

• structural engineers

• mechanical engineers

Name three natural forces that can move parts of a structure.

• rain, wind, and lightning

• rain, hail, and wind

• wind, snow, and earthquakes

• lightning, earthquakes, and snow

What is a compression and tension failure

• compression failure is when a structure bends, tension is when it bends

• compression failure is when a structure pops out, tension is when it pops out

• compression failure causes supporting parts of a structure to buckle or bend. Tension failure happens when two parts of the structure pull apart.

• Tension is when you become very angry

What is a control in a test?

• something that changes to see what effect it has in a test

• something that causes tension in a test

• something that does not change in a test

• something that changes once during a test

What can be accomplished through proper design and testing?

• fun

• Many structure failures can be predicted and avoided.

• structures can fail

• Scientists can make a hypothesis about the data.
