Distillation
Distillation Distillation is a common method used to separate liquid mixtures based on differences in their boiling points. When a liquid mixture is heated, the component with the lower boiling point vaporizes first. The vapor is … more
Solubility
Solubility When salt dissolves in water, a clear solution is formed. This is because the solute, salt, breaks down into particles so small that they are invisible to the naked eye and mixes evenly with the … more
Rock and Mineral Classification (AI Image Analysis)
Notes This program is a rock and mineral classification program utilizing artificial intelligence image analysis. When you take a photo of a rock on-site with a camera, the AI analyzes the image and identifies the types … more
Pendulum Wave
Pendulum wave A ‘Pendulum wave’ is a collective wave-like phenomenon that appears when pendulums (weights) of different lengths are arranged side by side. Because each pendulum has a different period depending on its length, they oscillate … more
Elements Texting Game
Type an element symbol to pop the bubbles. Type one of the element symbols shown on the right. Use the Backspace ⌫ key to delete a mistyped character. The list of element symbols that appear … more
Direction of earth’s gravity
Scientific definitions of ‘up’ and ‘down’ We live on the surface of the Earth and are always under the influence of its gravity. When we let go of an object, it falls “down,” and when we … more
Blocklab – Biological Classification Coding

Blocklab – Circular motion simulation
This is a simulation of circular motion (orbital motion) of an object using Blocklab. You can experiment with object motion by applying various variations to the block code.
Blocklab – Parabolic motion simulation
This is a simulation of parabolic motion of an object using Blocklab. You can experiment with parabolic motion of an object by applying various variations to the block code.
Blocklab – Block coding tool
Blocklab is a simulation creation tool built on Google Blockly that lets users assemble blocks to explore a wide range of dynamic experiments. With Blocklab, you can create algorithm-based dynamic simulations intuitively. The simulations you build … more
Solar wind and the aurora
Solar wind The Sun emits electrically charged particles. Because the Sun is mostly hydrogen, these particles are mainly protons and electrons. They travel through space at hundreds of kilometers per second. When solar activity increases, the … more
