Science Simulations
You can measure the voltages between 0 and 3.3V with micro:bit. Connect a 4.5V battery or USB power source to the micro:bit (3V batteries cannot be used). Do not measure excessively high voltages. It can damage … more
Color and Eye Recognition Visible light has various colors. Light has a different color depending on the wavelength (or frequency). So, how do people perceive color? Cone cells in the eye’s retina recognize color. There are … more
Boiling point and properties of substances All water boils at 100°C when heated, even if it has a different mass. In this way, the same kind of substance has the same boiling point regardless of quantity. … more
Magnetism of matter Materials can be divided into three types: ferromagnetic, paramagnetic, and diamagnetic, depending on how they react to an external magnetic field. Ferromagnetic In ferromagnetic materials, each atom acts like a magnet. In ferromagnetic … more
What is the difference between a magnet and an electromagnet? Let’s assume there is a small container you can’t see inside. There is a magnetic field around this container that can attract iron. Then, can you … more
Magnetic Force The magnetic force acts between two magnetic objects. Gravity only pulls, but magnetic force also has the force to push, including pulling force. When the different poles of the magnet are close, they pull … more
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
* 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
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
