What is air pressure?
Spider webs use this force to stay strong and stretchy.
What is tension?
This metal is often used to reinforce concrete in buildings.
What is Steel?
Isaac Newton was said to be the first scientist to discover this force, while eating under an apple tree.
What is gravity?
This helps keep tall structures balanced and upright.
What is use a wide base?
This bridge uses strong towers and curved supports.
What is an arch bridge?
A honeycomb’s shape helps it resist this force.
What is compression?
This property describes how much force a material can handle before breaking.
What is a material's strength?
This force is found where two objects meet. It can slow a moving object down.
What is friction?
This force pushes through arches and supports.
What is compression?
This natural structure supports a tree and keeps it standing.
What are roots?

What is flexibility?
An invisible but very "ATTRACTIVE" force.
What is magnetism?

What is a truss bridge?
This natural structure protects a turtle from predators and force.
What is a shell?
This material is heavy, very strong when squeezed, but cracks if pulled.
What is concrete?
Name the 4 internal forces.
What are tension, compression, shear, and torsion?
Adding weight to the bottom of a structure's...
What is stability?
This bridge uses long cables to hold up the road deck.
What is a suspension bridge?
This natural structure protects animals like crabs and insects. It's like a shell but has another name.
What is an exoskeleton?
This material is chosen for structures because it is flexible, renewable, and strong for its weight, but not as strong in compression as concrete. It can also bend slightly.
What is wood?
