| titleOfInvention | A study on the chemical and physical properties of various chalks |
| abstract | Through this experiment, as expected from the hypothesis, chalk chalk was measured to have a good writing feel, softness, and low coefficient of friction, resulting in more dust generation than other chalk. Of course, in the case of water chalk, almost no dust is blown, but it is characterized by the smell of alcohol due to the organic substances added during molding, and as a method for evaluating the toxicity of chalk as well as the viewpoint of fine dust, other components of chalk are made into a solution phase. I felt the need for experiments applied to aquatic organisms. As a result, there are many different types of measuring instruments for measuring fine dust, but the results of the Arduino II type of the laser type sensor measuring instrument made in this expedition showed some consistent data, and the Arduino I applied an infrared sensor. The meter observed that the deviation was very severe. Therefore, the important point in the measurement of fine dust has come to realize that the laser-type pen circulation method is very accurate when measuring, rather than the expensive fine dust measuring instrument.
