Science Simulations
Why does the night sky look dark? It’s dark at night. This seems obvious, but you’ll find something strange if you think about it a little. Shouldn’t the universe be bright if the night sky is … more
* By adjusting the temperature of the thermometer, you can observe the state of the water corresponding to the temperature. * Depending on the temperature of the water, some water molecules may evaporate. State of matter … more
Vacuum Jar A vacuum jar(or vacuum sealer, vacuum container) is a container that can remove air using a pump. Originally, vacuum jars were made as kitchen utensils to help meat soak in seasoning. Now, they are … more
We printed a plastic frame to use Javalab Logger (Microbit data logger system) conveniently. Microbit, expansion board, and batteries are integrated into one frame, making it more convenient. We provide the 3D printing data below. Here’s … more

This simulation allows you to measure speed as a function of fall height. You can measure the speed at two locations and change the ruler’s orientation. Free fall movement All objects on Earth are affected by … more
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
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 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
