Period 9 Chemical Reactions Chemical reactions happen in almost everything around us. Reactions are very important in everyday life‚ and science. Chemical reactions are the changing of substances to other substances by the breaking of bonds in reactants and the formation of new bonds in products. There are different types of chemical reactions such as combination reaction‚ decomposition reaction‚ single-replacement

Harmful Chemicals in our Environment Over the past century humans have introduced a large number of chemical substances into the environment. Some are the waste from industrial and agricultural processes. Some have been designed as structural materials and others have been designed to perform various functions such as healing the sick or killing pests and weeds. Obviously some chemicals are useful but many are toxic and their harm to the environment and our health far outweighs their benefit to

Show a piece of paper to students‚ then tear it in half. Discuss how paper can change yet still remain paper. Brainstorm with children for suggestions on how paper is changed. Accept all answers and write them on the board under the word “Physical Change”. As a class develop a working definition. Accept all suggestions for changing the paper since it is a brainstorming process. Student answers will become your Physical Property concepts. (shape‚ size‚ color‚ texture..) Students will be sitting

Chemical Proportionality (Carbonate and Hydrochloric Acid) Introduction: The purpose of this experiment is what happens when a solid substance‚ a metal carbonate is added slowly to a solution of an acid. We are finding methods of determining acid concentration. For us to balance certain equations‚ we will use a stoichiometry. For this experiment‚ we will need to set up the ratio and finding the concentration of HCI. Procedure: • Grab 4 different beakers. • Add a small amount of sodium carbonate
