Vacuum Jar
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 used more in science … more
Javalab Logger 3D Frame
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 the back. The reset … more
State of Water
* 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 The material around us … more
Free Fall Experiment 2
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 gravity. If there were … more
Simple Chemical Bonding Simulation
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 error. Chemical Bonding Except … more
Classroom Lottery Board v2 (Editable)
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 spin the roulette wheel. … more
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, it is in a … 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 nerve) → cerebrum → … 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 the magnetic needle placed … more
Spectrum Analysis of Sound 2
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 not stored on servers, … more
Gravity Simulator
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 a pulling force on … more
