Ecosystem Simulation v2
About this simulation The length of the red bar shows the vitality. It gradually decreases with time. When the vitality is zero, it naturally dies. The green bars show stamina (nutritional status). If it is short, … more
Reaction time measurement (visual and auditory responses)
Reaction time In a conscious response, it takes some time to respond to a stimulus. This is because signals require time to be transmitted and processed. Reaction by vision: stimulus → eye → sensory nerve (optic … more
Magnetic Field around Magnet(or Earth)
Magnetic field around magnet The space where the magnetic force of the magnet acts is called a ‘magnetic field.’ The direction of the magnetic field is determined in the direction indicated by the N pole of … more
