Generation of Static Electricity by Friction Matter is made up of extremely small particles called atoms. An atom consists of a positively charged (+) nucleus and negatively charged (−) electrons. Normally, the amounts of positive and … more
Breathing The lungs are located in the thoracic cavity, which is surrounded by the ribs and the diaphragm. Because the lungs do not have muscles of their own, they cannot move by themselves. Instead, movements of … more
Magnetic Field Produced by an Electric Current A magnetic field is produced not only around a magnet but also around a wire carrying an electric current. This can be observed by watching the needle of a … more
The Digestive Tract from a Topological Perspective In topology, the exact length, thickness, or curvature of an object is less important than its connectivity and the number of holes it has—properties that remain unchanged as long … more
When the red (R), green (G), and blue (B) circles are made very small and placed close together, they eventually become too small for the human eye to distinguish individually. Instead, the eye combines and averages … more
Pulse Blood vessels are elastic. When the heart contracts, the blood vessels dilate; when the heart relaxes, the vessels constrict. Hemoglobin in the blood absorbs particular light. Therefore, when light is applied to human tissue, the … more
Life game It was in 1970 that Martin Gardner introduced J.H. Conway’s “Life game” in Scientific American, an American science magazine. The “Life game” is not a conventional game that requires continuous input from a player. … more
This is the start page for the game where you drag a satellite to create an orbit as close to a perfect circle as possible. When the teacher creates a game, a QR code for joining … more
You can set an alarm to sound at specified minute intervals. It is useful for taking measurements at regular time intervals in a science laboratory. You can easily determine the corresponding time for each measurement count.
This page is the start screen for the Element Symbol Typing Bubble Game. When a teacher creates a game, a QR code for joining and a live scoreboard will be displayed on the screen. Students can … more
How Colored Shadows Work This simulation demonstrates both the principle of additive color mixing and how colored shadows are formed. To understand colored shadows, there are a few important concepts to know. Each flashlight emits only … more
Real image and virtual image Looking at an object, we feel there is an object in it. By the way, if you feel that there is something, we say there is an ‘image’, even if there … more
