Density Tower (Comparison of densities of various liquids, plastic, iron, and gold)
Density Tower A density tower is made by stacking several liquids in one container according to differences in density (mass per unit volume). Liquids with higher density sink to the bottom, while liquids with lower density … more
Recrystallization (Principle of precipitation)
Lower the temperature to precipitate some of the substances as a solid, then filter them through filter paper. Recrystallization Recrystallization is a method of separating and purifying a substance by using the property that the amount … more

🟤 Cynognathus 🟢 Glossopteris 🟠 Lystrosaurus 🟣 Mesosaurus Move the continents so that the fossil distributions connect into one continuous pattern. Can all the continents be joined together into a single landmass? Distribution of Fossils The … more
Seismic wave observation and the discovery of the outer core
Seismic Wave Observations and the Discovery of the Outer Core The process by which Earth’s internal structure—especially the existence of the outer core—was revealed through seismic wave observations is a major discovery in Earth science. When … more
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
