Science Simulations
Solar wind The Sun emits electrically charged particles. Because the Sun is mostly hydrogen, these particles are mainly protons and electrons. They travel through space at hundreds of kilometers per second. When solar activity increases, the … more
Characteristics of Gases Unlike solids and liquids, gases have the following unique characteristics: 1. They have no definite shape or volume Gas particles move in all directions and can fill any part of a container. Therefore, … more
Solar System All the orb bodies that revolve around the sun and their space are called the solar system. The celestial bodies that make up the solar system include the eight planets revolving around the sun … more
What would happen if you brought a mercury barometer to Earth, the Moon, Mercury, Venus, and Mars? Here, we assume that the mercury barometer has a U-shaped tube: one side is open, and the other side … more
This simulation analyzes the sound around you and displays it as a spectrum. The simulation works by recognizing the surrounding sounds. In the case of PC, please grant permission to use the microphone. Voice data is … more
Observe how the density distribution of the atmosphere changes as gravity (gravitational acceleration) is varied. The total kinetic energy of the air particles is assumed to be constant. Gravity is assumed to act uniformly, and no … more
Heat engine A heat engine is a machine that operates by moving energy from a hot space to a cold space. In this process, the heat engine converts some of the heat energy into mechanical energy. … more
Torricelli’s Experiment The first person to measure the magnitude of air pressure is Italian scientist Torricelli. He was filled with mercury (Hg) in a glass tube with one end blocked. And he stood upside down in … more
Boyle’s J-tube experiment Boyle’s J-tube experiment is an experiment that Boyle did to prove his law. Boyle experimented with pouring mercury into a J-shaped glass tube with one side blocked. At first, the heights of mercury … more
Doppler Effect By listening to the ambulance’s siren, we can tell if the ambulance is coming or going. When an ambulance approaches with a siren, the sound wave’s wavelength becomes shorter (higher note), and when it … more
Hz Height and loudness of the sound When we often say that a sound is ‘low’ or ‘high,’ we are referring to the height of the sound. The height of the sound is completely different from … more
Assume the pressure inside and outside the balloon is equal at 1 atmosphere. For ease of calculation, the volume and mass of the balloon and string are assumed to be zero. Pressure on a Balloon In … more
