An object experiences an upward force called buoyant force when immersed in a fluid. This upward force opposes the weight of the object, resulting in a decrease of its weight. Archimedes’ principle states that when an object is partially or fully immersed in a liquid, it experiences an upward thrust (buoyant force) which is equal to the weight of the fluid displaced by the immersed part of the object.

Embark on a captivating journey through Archimedes' principle as we unravel the wonders of fluid dynamics in this immersive simulation!

A catalyst is a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change. Enzymes are naturally occurring catalysts responsible for many essential biochemical reactions.

Energy can neither be created nor destroyed. Energy can only be converted from one form to another. For example, potential energy can be converted into kinetic energy during a ride on a roller coaster.

Changes Between Kinetic and Potential Energy

Chemical change is a change in matter in which the substances that make up the matter change into new chemical substances. The physical and chemical properties of the new chemical substances that formed are entirely different. The signs that indicate the formation of a new type of matter include the formation of bubbles or a change in energy, color or odor.

Codominance is the type of interaction in which both the alleles of a gene are observed in a phenotype. Coat color in some cows is an example of codominance. A cow in which one allele for red coat color is inherited from one parent, and one allele for white coat color is inherited from another parent, will have both red and white hair.

We all know of DNA as the genetic material of our cells and the process of DNA replication is SO important. Let's find out why!

Earth acts as a magnet. It has a north magnetic pole and a south magnetic pole. Earth's magnetic field extends from the Earth's interior out into space.

A force acting between charged objects, even when they are not in contact with each other, is known as an electric force.

The matter around us is of two types, pure substances and mixtures. Pure substances have the same composition throughout. They can be classified as elements or compounds. A mixture consists of two or more elements or compounds not chemically combined together.
The properties of a compound are different from the properties of each of the elements that make up the compound. In mixtures, all of the substances that make up the mixture retain their original properties.
