"Making a Frame" Shape and Structure PPT Teaching Courseware

Part 1: Importing new lessons

What do the buildings under construction and the machinery on the construction site—tower cranes and tic-tac-toe frames—look like? What do the objects in these pictures have in common? A skeleton structure like this is called a frame structure in architecture. In this lesson, we will make a framework together and study the framework structure.

Making framework PPT, the second part of the content: learning new lessons

What are the characteristics of these frame buildings?

Frame structures can support objects, function as columns and beams, and require very little material.

Material preparation: chopsticks or plastic straws, rubber bands, scissors. (As shown on the right)

Use chopsticks and rubber bands to tie up the frame

Observe the difference between them when a force is applied to them. Which one is more likely to deform?

Can we reinforce the rectangular frame?

The triangular frame is stable and the quadrilateral frame is unstable. Adding a diagonal rod to the quadrilateral frame can strengthen the quadrilateral frame.

Where can I add slashes to strengthen this frame? If the cube frame carries downward pressure, where can the slash be omitted?

If it is subject to downward pressure, in order to save materials, no inclined rods can be added at the top and bottom, and only one inclined rod can be added to each of the four surrounding sides.

Make framework PPT, the third part: conclusion summary

1. A skeleton structure like an iron tower is called a frame structure.

2. The advantage of the frame structure is that it can use less material to construct huge objects and support a large space.

3. The added diagonal rod plays the role of "pull" and "push" to prevent the frame from deforming.

4. The triangular frame has stability and can be used to strengthen the frame structure.

Making framework PPT, Part 4: Classroom exercises

(1) Multiple choice questions

1. How many diagonal bars are needed to reinforce the cube? ( )

A 4 sticks B 6 sticks C 8 sticks

2. The best way to strengthen a square frame is to add ( )

A. Horizontal bar B. Inclined bar C. Vertical bar

3． Which of the following frames is not easily deformed ( ).

A cube B cuboid C triangle

(2) Judgment questions

1. Triangles have stability. ( )

2. Triangle and quadrilateral are the most basic frames, and the quadrilateral frame has the best stability. ( )

3． The triangular structure is easier to collapse. ( )

Making framework PPT, part 5: homework assignments

1. Can you use the knowledge we just learned and use small sticks to make a cube frame?

2. By making the cube frame, try to make a simple and strong bookshelf for yourself.
