Science Simulations
Cell division Multicellular organisms like humans are made up of cells of varying shapes and functions. Most cells are so small that they can see them only under a microscope because once they reach a certain size, they no longer … more
Respiratory organ To maintain life, we absorb oxygen from the air. And we export carbon dioxide from the body. Human respiratory organs include the nose, organs, bronchi and lungs. Each bronchus in the lung continues to diverge and taper. The … more
Potential energy The potential energy of an object is the energy stored in an object or system. Denoted as Ep. Generally speaking, potential energy refers to potential energy caused by gravity and is proportional to an object’s mass and height. … more
Potential energy due to gravity Lifting heavy objects increases the potential energy of the object. The amount of work done when lifting an object of mass m by height h can be obtained as (Potential energy by gravity) Ep(J) = … more
About this simulation, When you press the button, you can see the corresponding strata. Combining the layer, you can create a variety of stratum. This simulation is presented as a mathematical model. Actual strata may be different.
Lever A lever is a tool that transmits force using a rod. With a lever, you can work with it having little force. The length of the lever can adjust the minimum force required to move the lever. Work at … more
‘Work’ in science ‘Work’ in science and ‘work’ in everyday life is a little different. In science, ‘work’ is to apply a force to an object and move it in the force’s direction. In the following cases, It is said … more
It is only the sun that shines by itself in the solar system. Earth and moon do not emit light themselves. The earth and the moon only reflect the light of the sun. Since the earth and the moon have … more
Assuming that the current flowing in the wire is in the X-direction, the magnetic field is in the Y direction. Then, what direction is the electromagnetic force? ‘Homopolar motor’ refers to a motor operated by using only one polarity of … more
This simulation assumes that the loading dye is 50bp and the marker is 50bp. (‘bp’ is a unit showing the number of base pairs of DNA.) Electrophoresis Electrophoresis is a chemical phenomenon in which an electric charge in a solution … more
