Question:
What type of structure is a tree?
Answer:
What is a; natural structure.
Question:
What structural form is a mug?
Answer:
What is a; shell structural form.
Question:
What is structural stability?
Answer:
Structural stability is the centre of gravity of an object. Without the centre of gravity, a structure would not be stable.
Question:
What is force?
Answer:
A force can be a push or pull on an object. This can make the object change shape, or movement.
Question:
What does it mean when an object has symmetry?

Question:
Explain what the centre of gravity is.
Answer:
The centre of gravity is an invisible point where the mass is centred in an object.
Question:
Explain what external and internal forces are.
Answer:
External force: 'An external force will act upon an object from outside of the object'.
Internal force: 'An internal force is when one part of a structure acts on other parts of the same structure.'
Question:
Is the Eiffel Tower symmetrical?
Answer:
Yes! The Eiffel Tower looks the same on both sides, if you cut it in half.

Question:
Name 3 objects that have a 'frame' structure.
Answer:
A 'Frame Structure' has a frame to the object. For example, a house needs to have a frame, in order for it to be built.
Question:
How do you indicate where the centre of gravity is?
Answer:
The centre of gravity is always located where the mass of the structure is.
Question:
What is an example of 'compression'?
Answer:
Compression: The pressure between 2 objects.
Example: When you sit down on a chair, you are pushing down on the chair. (You are making compression to the chair.)

(Does it sound correct to your peers?)
Question:
What is an example of 'Tension'?
Answer:
Tension: A stretch that happens.
Example: Stretching your hand up in the air to ask a question in class.
