Continental Drift (Continental Drift Theory)
Move the continents to create a connected supercontinent (Pangea).
Covalent Bonds of Hydrocarbon
Why are the outermost electrons of atoms important? The outermost electrons of an atom are essential indicators of the properties of matter. Period 2 and 3 elements, such as carbon, oxygen, and nitrogen can exist in … more
Making Molecular Models (Whiteboard)
You can create molecular structures by dragging the atoms. Atoms that no more needed can be returned to the periodic table.
Incandescent light bulb (heat dissipation of resistance)
Resistance Materials have different degrees of impeding the flow of electric current depending on their type and shape. Most materials, except metals, do not conduct current well. On the other hand, metals have low resistance and … more
Capacitor Application Circuit
A capacitor is an electronic component made by placing two metal plates close to each other. Capacitors store electrical energy in the form of an electric field. * This simulation only works while pushing with the … more
Law of Definite Proportions
Law of Definite Proportions In a reaction where hydrogen gas is burned to produce water, two hydrogen atoms combine with one oxygen atom. Hydrogen gas and oxygen gas always react in a ratio of 2:1 to … more
The charging and discharging characteristics of capacitor。
Switch up to start charging, and switch down to start discharging. The measured voltage is recorded automatically when charging or discharging starts. You can change the measuring point by moving the probe. For accurate measurement, operate … more
Capacitor 2
Capacitor A capacitor is an electronic component that temporarily holds charges. The stored charges can work while flowing again. Compared to a river flow, a capacitor can be likened to a dam that holds a river. … more
Half Adder
Half Adder An adder is a logic circuit that can perform additional operations on binary numbers. It can be composed of only three types of logic circuits: AND, OR, and NOT gates. Bit addition is handled … more
Logic Gate
Logic Gate Logic circuits are responsible for arithmetic operations in a computer. All numbers are converted to binary for the logic circuit to work. A binary number is a number system that consists only of the … more

Cassegrain Reflector
Cassegrain Reflector The Cassegrain reflector(telescope) was designed by French engineer Laurent Cassegrain to compensate for the shortcomings of the Newtonian telescope. Light reflected by the concave mirror is incident on the convex mirror. Focus is created … more
