Description

"The relationship between variables represented by tables" The relationship between variables PPT courseware 5

Knowledge base: This lesson is based on what students have learned about exploratory rules and statistical graphs in the seventh grade textbook. Students can understand the concepts of variables, independent variables, and dependent variables in the form of tables, which is also very important for learning function knowledge in the future. of.

Activity experience basis: In previous studies, students have experienced group learning, cooperative communication and other forms. They can solve some practical problems and have the ability to cooperate in learning.

Study method: independent inquiry method, and cooperative inquiry method, fully mobilize students' enthusiasm for learning, and successfully grasp the key points of this lesson and overcome difficulties.

In the "Time for the Car to Slide Down" experiment:

1. The height h of the support and the time t for the car to slide are both changing, and they are both variables.

2. The time t for the car to slide down changes with the change of the height h of the support.

3. The height h of the support is the independent variable.

4. The time t for the car to slide down is the dependent variable.

5. The distance the car slides down (the length of the board) has not changed. The quantity that remains unchanged during the change is called a constant.

6. With the help of tables, you can express how the dependent variable changes as the independent variable changes.

In the process of change, if there are two variables x and y, and y changes as x changes, we call x the independent variable and y the dependent variable.

1. The independent variable is a quantity that actively changes within a certain range.

2. The dependent variable is the quantity that changes as the independent variable changes.

3. The table can show how the dependent variable changes as the independent variable changes, and can also help us make preliminary predictions about the change trend.

Effect presets

1 Breakthrough key point: be able to discover the relationship between variables from the table and describe it in your own language.

2 Overcome difficulties: be able to find variables, independent variables, and dependent variables in specific situations.

3 Possible problems: Some students may not be able to fully grasp the trend when trying to use tables to predict changes.

4. There are many difficulties in actual operation regarding the activity experiment of the trolley's sliding time. Although a stopwatch is easy to prepare, the accuracy of the measurement results is difficult to grasp.

5. Since the time used for experiments is not easy to grasp, it may lead to tight time for subsequent study and discussion.
