Development of the environmental education materials with environmental measurement tools for elementary schoolchildren.

学校认识到环境教育的重要性，并积极开展环境教育。然而，环境教育往往是用主观的方法来教授的。这种测量方法对客观认识自然和环境是有效的。即使是小学生，如果有合适的教学工具，也可以用客观的方法进行环境教育。然后，我们开发了名为“动手传感器”的测量工具（数据记录器），用于环境教育。Hands on Sensor有以下特点。即使是小学低年级的学生也可以掌握。取出来是可能的。可分为手动测量和自动测量两种。仅使用此本体即可存储测量数据。传感器可以更换。我们从环境教育中的一个测量对象中选择了可以使用“Hands on Sensor”的测量对象。我们为这些测量对象开发了传感器单元。我们实验开发的传感器单元有“空气温度传感器”、“水温传感器”、“相对湿度传感器”、“电流传感器（商用电源采用宽带电流传感器）”、“pH传感器”等。此外，我们还研究了“动手传感器”在环境教育和科学教育中的实际使用方法。

The importance of an environmental education is recognized and works actively at the school. However, an environmental education is often taught by a subjective method.The method of measurement is effective to the objective understanding of nature and the environment. Even the elementary school children can do an environmental education by an objective method if there is an appropriate teaching tool. Then, we developed the measurement tool (data logger) called "Hands on Sensor" for an environmental education.Hands on Sensor has the following characteristics. It is possible to master even by the elementary school lower classes student. It is possible to take out. It can measure by the manual operation and the automatic operation. It is possible to store the measurement data by use only this body. The sensor can be exchanged.We chose the measurement object which could use "Hands on Sensor" from a measurement object in environmental education. And we developed sensor units for these measurement objects. The sensor units that we developed experimentally are "an air temperature sensor", "a water temperature sensor", "a relative humidity sensor", "a wait electric current sensor (a commercial power supply use wide band electric current sensor)", "a pH sensor", etc.Furthermore, we studied a practical use method of "Hands on Sensor", in the case of environmental education and science education.
