IntroductionThe blind cannot see

anything.

There are problems in science learning.But they can hear and touch.

Making “Light Probe”

Combined with the designed experimental groups

Objective Inventing “Light Probe” for helping

people to learn science Combining “Light Probe” with the designed experimental groups named

"the straight line of light" and "the equality of the angle of incidence and the

angle of reflextion The averge point of pleasure of the

blind people in Both experimental groups pass the low grade that is

more than 3.5.

Procedure of the experiment

1. Connecting the electrical circuit with the project board

2. Inventing “Light Probe”3. Making designed experimental

group named "the straight line of light"

4. Making designed experimental group named "the equality of the angle of incidence and the angle of reflextion

5. Interview the pleasure of the volunteer

Conclusion1. Successful in inventing the Light

Probe 2. average point of pleasure of the

blind people in "the straight line of light" and "the equality of the angle of incidence and the angle of reflextion" equal 3.92 and 3.79, respectively. Both points pass the low grade that is more than 3.5.
