"Looking for Arches" Shape and Structure PPT Courseware

Description

"Looking for Arches" Shape and Structure PPT Courseware

The lesson "Finding Arches" is selected from the fourth lesson of the "Shape and Structure" unit in the sixth grade volume of the textbook "Science". In the third lesson "The Power of Arches" exploration activity, students have learned about the characteristics, similarities and differences of arches through experimental research, which further expanded and deepened their understanding of arch structures.

main content

what shape are they

Analyze the reasons behind the shape of each part of a plastic bottle

Understand the arch structure in living organisms

Teaching analysis

By "looking for the arch structures around us (clarify the original idea) - looking for the connection point between the arch and the dome shape and the spherical shape (finding evidence) - explaining the force principle of the dome shape and the spherical shape (explanation) - clarify The concept of arcs such as domes, spheres, etc. and further deepens the understanding of arch structures through the analysis of "plastic beverage bottle shapes" and "arch structures of living organisms", develops students' original understanding, and forms a scientific concept.

Study method analysis

1. Students learn knowledge through games in lively and interesting classes.

2. Students observe graphics in life and learn with pleasure.

1. Pre-class games:

Several classmates held hands and formed a circle. Everyone tried to move away. Can they go away?

Students try to explain the phenomena in the game.

Through the game, it is hinted to students that circular shapes can offset each other's forces, paving the way for the later explanation of the dome-shaped force principle.

2. Import

(Show pictures of dome-shaped objects and buildings) In order to understand whether they are related to arches, what aspects should we study?

3. Study the pressure-bearing characteristics of dome-shaped and spherical shapes

1. Observe dome-shaped objects. What are the characteristics of their shapes?

2. (Provide arched bars) Why are these objects dome-shaped, and how well do they withstand pressure? In what way can we understand?

3. Can you explain the characteristics of the dome shape to withstand pressure?

4. Research on the shape of plastic bottles

1. (Show a plastic bottle) This is a very common plastic bottle in life. Where does its shape design include an arch-like structure?

2. Can you reason about the purpose of designing these shapes based on what we have learned in this lesson and your daily experience?

5. Arches in living organisms

We studied artificially designed objects. Are there arched structures in living organisms in nature (such as humans, animals, plants)?

6. Summary

What do you think after studying the arch?
