Jean Piaget had many theories on child development one of which was conservation. He believed that children of certain ages did not understand the concept of conservation‚ such as children believing that the amount of water changes if poured from a short‚ wide container into a tall‚ thin container. Many people criticised Piagets theory because they believed that children actually could conserve at a younger age than Piaget had initially stated. This essay is going to discuss Piaget’s theory of conservation

| Latent heat is a science term used to describe the amount of energy that has been absorbed or released when a substance goes through the process of changing states. | Latent Heat of Fusion - heat absorbed by a unit mass of a solid at its melting point in order to convert the solid into a liquid at the same temperature The heat absorbed as a substance changes phase from liquid to solid‚ a process called fusion or solidification. For water‚ Latent Heat of Solidification - heat liberated

maintains the properties of that element. And element is a pure substance made of only one kind of atom. A compound is the substance that is made from the atoms of two or more elements that are chemically bonded. Water is an example of a compound because it is one of many compounds that consist of molecules. The hydrogen and oxygen molecules are chemically bonded to form a water molecule.

Abstract Different substances react in various ways when exposed to heat. The amount of energy necessary to heat a certain amount of water by one degree is different than that of another liquid or substance. The technical term used to determine this characteristic is called heat capacity or specific heat capacity. The purpose of this experiment is to find the heat capacity of water‚ orange juice‚ and olive oil. A couple of very specific equipment is needed in order to complete this experiment

Aim To investigate in the amount of antioxidants present in the two given tea samples for four consecutive brews each. Introduction Hypothesis: The amount of antioxidants would decrease as the number of brews increases. Biological principal: An antioxidant is a molecule that inhibits the oxidation of other molecules. Oxidation is a chemical reaction involving the loss of electrons. Oxidation reactions can produce free radicals. These radicals can start chain reactions. When the chain reaction occurs
