1.1 Chemistry A. What Is Chemistry? * Because living and non-living things are made of matter‚ chemistry affects all aspects of life and most natural events. * Matter- is anything that has mass and occupies space. * Chemistry- is the study of the composition of matter and the changes that matter undergoes. B. Areas of Study * Five traditional areas of study are organic chemistry‚ inorganic chemistry‚ biochemistry‚ analytical chemistry‚ and physical chemistry. * Organic

TOPIC 2 Metals The History of Metals * Uses of metals through history: * Copper Age (3200-2300 BCE) – copper and tin were most common metals‚ and were used for ornaments‚ weapons and tools. * Bronze Age (2300-700 BCE) – copper‚ tin and bronze were used for tools‚ weapons and transport. They produced bronze by heating copper and tin with charcoal. * Iron Age (1000 BCE – 1 CE) – iron steel and lead was used for tools‚ weapons and pipes. Iron is much harder than bronze.

9/19/2012 Experiment #1-Density Aim: Learn how the process of distillation occurs. Observe how distillation separates alcohol from wine. Method: Distillation is based on the fact that the matter can exist in three phases - - solid‚ liquid and gas. As the temperature of a pure substance is increased‚ it passes through these phases‚ making a transition at a specific temperature from solid to liquid (melting point--mp) and then at a higher temperature from liquid to gas (boiling point--bp). Distillation

1) Demonstrate understanding of the terms atom and molecule. Atom= Smallest Unit of Matter Molecule= 2 or more atoms chemically bonded. 2) Describe paper chromatography. 3) Interpret simple chromatograms. A method used to separate a Solution‚ using a Paper and a beaker of water. The Substances in the Paper go up depending on their Mass. We can say that a Solution has the same substance as another solution because they form a line of the same height. 4) Describe methods of separation
