Background technique
Pendulum experiment is invented by Switzerland Based on Constructivism developmental scientist Pi Yajie, deducts energy for testing children
The experiment of range degree.Experiment the result is that: the children of formal operational stage have had abstract logic inferential capability, can be with false
If deducting, the conclusion that inference goes wrong.
On scientific experiment classroom, teacher needs that students is led to do pendulum experiment, probes into influence of the angle to the speed of pendulum,
The weight of pendulum and the relationship of slew rate degree are studied, Experimental Research process is as follows:
Experiment one: influence of three different angles of research to the speed of pendulum, protractor assist in 30 degree of angles, 60 degree of angles,
An angle of 90 degrees.
Experimental method: the number of rounds that timing test is put in 15 seconds, number of oscillations is more, illustrates that speed is faster, number of oscillations
It is less that speed is slow, therefore the speed of pendulum is measured with number of oscillations.Finally develop whether angle difference has shadow to the speed of pendulum
It rings.
The problem of research one: the angle of pendulum and the length velocity relation of pendulum
Experiment condition: constant: hook code one, to weigh ten grams.
Single search time: 15 seconds in limited time.

It influences.
Experimental method: the number of rounds that timing test is put in 15 seconds, number of oscillations is more, illustrates that speed is faster, number of oscillations
It is less that speed is slow, therefore the speed of pendulum is measured with number of oscillations.Finally develop to vary in weight whether have shadow to the speed of pendulum
It rings.
The problem of research two: the weight of pendulum and the relationship of slew rate degree
Experiment condition: constant: 15 seconds (time is constant in limited time) in limited time
The angle of pendulum is 90 degree (angle is constant)
Study variable: the weight of pendulum
Experimentation: laying out the hook code for placing different number, and single hook code weight is 10g, studies ten grams, 20 altogether
Gram and 30 grams of hook codes the speed of pendulum is influenced.Timing is surveyed 15 seconds, counts number of oscillations to measure the speed of pendulum.
