Description
"Inverse Proportional Relationship" Proportional PPT Courseware
1. Explore new knowledge
Pour the same volume of water into cups with different base areas.
The changes in the bottom area of the cup and the height of the water are as follows.
Observe the table above and answer the questions below.
(1) What two quantities are in the table?
(2) How does the height of the water change with the size of the bottom area of the cup?
(3) What is the product of the corresponding bottom area of the cup and the height of the water?
As can be seen from the above table, the height of the water and the bottom area of the cup are two related quantities. The height of the water continues to decrease as the bottom area of the cup increases, and the height of the water is related to the bottom area of the cup. The product of areas is always constant.
In the above experiment, height and bottom area are inversely proportional quantities, and height is inversely proportional to bottom area.
2. Application of knowledge
(1) What two quantities are in the table? Are they related quantities?
(2) Write several sets of products of the two corresponding numbers in these two quantities, compare the sizes of the products, and talk about what this product represents.
(3) Is there an inverse relationship between the number of days to transport goods and the number of tons transported per day? Why?
3. Assign homework
Homework: Exercise 9 on page 51, questions 8, 9, and 10.
