Learning Targets
Explain the difference between a pure substance and a mixture.
Understand the relationship between atoms, elements, mixtures, compounds.
Explain how compounds behave differently from the elements that they are made of. Give a specific example of this.
Be able to interpret a chemical formula
Be able to write word equations for simple chemical reactions
Identify the products and reactants in a chemical equation
Know the five signs that demonstrate that a chemical reaction has taken place
Be able to describe what it is meant by a precipitate
Be able to draw particle diagrams of solids, liquids, and gases, molecules, and crystals
Know how to read a periodic table (what part is a group/period?)
Know generally where metals and non-metals are organized in the periodic table
Know the three magnetic metals
Be able to use the symbols for the first 20 elements
Enduring Understanding
All of matter is made of tiny, indivisible particles called elements, which are made of atoms. The atoms of elements can exist alone, molecules, in mixtures or compounds with other elements. Different elements have behave differently, and are organized by how they behave in what is called the periodic table. Elements can be chemically reacted to join other elements to make compounds, which can further be reacted to form different compounds that have completely different properties. In a chemical reaction, the amount of material that is reacted is the same as the mass of material that is produced.
