Javalab Logger – Intelligent Science Lab Solution Javalab Logger is a wireless MBL (Microcomputer Based Laboratory) system using the micro:bit. It runs on the web browser, and there is no need to install a separate program. This system requires a … more
This simulation shows the surrounding sounds as waveforms. Please turn off the silent mode on your mobile device to allow microphone detection. For PC, please allow permission to use the microphone. No voice data is stored anywhere.Privacy Policy Why are … more
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 the micro:bit. If the … 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 three kinds of cone … 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. But different substances express … 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 materials, the atomic magnets … more
Kinetic theory model Gas particles are constantly moving in all directions. However, we cannot observe these gases because they are very small. The “Kinetic theory model” can replace these invisible gas particles with beads and make them visible. Metaphor of … 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 figure out whether the … 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 each other, and when … 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 full of stars? If … 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 The material around us … 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 used more in science … 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 the back. The reset … more
