"Finding Arches" Shape and Structure PPT Courseware 2

What are the characteristics of an arch carrying gravity?

There are many arc-shaped objects around us. Do they have similar characteristics to arches?

What are the similarities between domes and arches?

Try to explain the pressure-bearing characteristics of the dome shape.

1. The dome shape can be seen as a combination of arches.

2. It has the characteristics of arch bearing large pressure.

3. And it does not produce outward thrust.

Carefully observe the upper part of the plastic beverage bottle. What are the shapes of the middle and bottom, and what are the other shapes on the surface.

Upper part: dome-shaped (some are obviously conical, and the mouth of the bottle is cylindrical.

Middle part: The bottle body is cylindrical, with annular arches, vertical arches or other convex and concave shapes on the surface.

Bottom: concave inward, similar to a dome shape

Did you answer it correctly?

If you answer correctly, you will receive a sticker. Please put it on your left cheek. Be honest!

Observe the cut plastic bottle. Are the thicknesses of each part the same? Which part is the thickest and which part is the thinnest?

The thickness of each part of a plastic bottle is different. The thickest part is the bottle mouth, and the thinnest part is the bottle body.

What scientific principles are involved in the shape design of plastic beverage bottles?

Invite students to communicate in groups, speak out their ideas boldly, and strive to become young scientists who are brave enough to discover and explore.

The students performed really well today,

I hope that the students will perform better in the next class, and we will see you next time!
