Crab Island is located on the north side of the Destin Bridge at the entrance of the Choctawhatchee Bay. It is only accessible by boat (or kayak or standup paddleboard if youâre in the mood for a good workout) due to the distance from shore and the strong currents and boat traffic that surround it.o a Google search for Crab Island and youâre likely to find pictures of a drunken party crowd. And parts of Crab Island are like thatâ¦sometimes. The good news is the real-life image is much different. If youâre with your family and you want to avoid the party scene, you can.
Likewise, a chemical change is required to break down a compound into its constituent elements. Water can be broken down by passing a powerful electric current through it. This process, known as electrolysis, separates water into hydrogen and oxygen, both of which are highly flammable gases. The fact that they can be joined to form water, a substance used for putting out most kinds of fires, illustrates the types of changes elements undergo when they join to form compounds.
Let students know that in this chapter they will explore what happens during a chemical change. In a chemical change, the atoms in the reactants rearrange themselves and bond together differently to form one or more new products with different characteristics than the reactants. When a new substance is formed, the change is called a chemical change. As a demonstration, light a candle and explain what is happening using the terms reactants, products, and chemical reaction. Explain that in most chemical reactions, two or more substances, called reactants, interact to create different substances called products. Tell students that burning a candle is an example of a chemical reaction. Materials for the Demonstration
