Science Simulations
The ideal gas equation is a formula that expresses the law of the relationship between pressure, volume, number, and temperature of ideal gases. With this simple equation, you can calculate the remaining variables you don’t know. … more
This simulation supports multitouch. Nature of gas Since the gas can not be seen or touched, a little imagination is needed to understand the ‘nature of the gas.’ In most everyday life, people often do not … more
* If you are asked to access your location, please allow it. * Your personal data is not stored on the server. * For iOS devices, please allow location access as follows. Day and night The … more
Why does a slightly curved path take less time than a straight path? Ants can move faster on flat stones than on rugged grass. Therefore, travel time is the shortest on slightly curved paths. This principle … more
Light has both particle and waves properties at the same time. Likewise, de Broglie (France, 1892 – 1987) thought that such things as electrons that had so far been considered particles might possess wave nature (1932). … more
You can drag the path of light. Refraction is the bending of a wave caused by a change in its speed as it moves from one medium to another. This occurs because of the slow speed … more
Pulse Blood vessels are elastic. When the heart contracts, the blood vessels dilate; when the heart relaxes, the vessels constrict. Hemoglobin in the blood absorbs particular light. Therefore, when light is applied to human tissue, the … more

Galton Board The Galton board is a tool for visualizing the principles by which the binomial distribution is created. Early Galton boards were made with wooden poles and beads that rolled down. Francis Galton, who created … more
Neutralization reaction The reaction of an acid and a base to form water is called a neutralization reaction. When an acid and a base react, hydrogen ions from the acid (H+) and hydroxide ions from the … more
You can use a Micro:bit as MBL by connecting a DS18B20 temperature sensor. If no sensor is connected, the Micro:bit built-in thermometer value is output. Thermal equilibrium experiment between hot and cold water The sensor connects … more
