Science Simulations
All atomic models showed only the electrons in the outermost shell. All chemical bonds are depicted as planar, but in reality, they can have three-dimensional structures. ‘In case of unstable, display in red’ may contain an … more
It is a lottery roulette that can be used in various places. You can edit the items displayed on the roulette. If you turn on the checkbox, the winning numbers will be deleted each time you … more
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
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
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
This simulation … Applied a geocentric coordinate system. Air friction is ignored. Covers fall and orbital motion due to Earth’s gravity. (However, the same can be applied to other celestial bodies.) Gravity Objects with mass exert … more
Iris muscles In the iris, the ‘Iris sphincter muscle’ constricts the pupil, and the ‘Iris dilator muscle’ enlarges the pupil. Both muscles work in reverse, controlling the size of the pupil. Ciliary body connected to the … more
The fluid in the beaker is water, and its density is assumed to be 1 g/mL. The volume of the object is assumed to be 100 mL. Buoyancy When we wear a life jacket, our bodies … more
Why is the submerged volume important to understand buoyancy? It is so famous that the 3rd-century Greek philosopher Archimedes shouted “Eureka!” and ran out of the bathhouse naked. （What did Archimedes find out? – Quotations from … more
It is an optical experiment simulator consisting of a slit laser, lenses, and mirrors of various shapes. You can experiment by dragging the tool you want. Slit lasers are rotatable. Try dragging the red icon behind … more
This simulation allows you to measure speed as a function of fall height. Free fall movement All objects on Earth are affected by gravity. If there were no friction with air, the speed of any object … more
