1. Day 1: 2/4/11

2.  Big Idea (for this unit): Periodic trends in the properties of atoms allow for the prediction of physical and chemical properties.  Today’s Concept: Trends in the periodic table can predict the properties and behaviors of elements.

3.  At the end of today, you will be able to: 1. know that the boxes on the Periodic Table are each for a different element. 2. Know what an element is. 3. conduct tests for physical and chemical properties. 4. distinguish between physical and chemical properties.

4.  Opener: Answer the “What Do You Think?” question in your packet. Discuss your answer in small groups and as a class.  For You To Do: Test for physical and chemical properties of metals and nonmetals in the lab. Complete this section of the packet.  Discuss observations as a class.  Powerpoint presentation on elements and properties  Closure Question: What is the difference between a chemical and a physical property?  Take Home Assignment: Safety Poster due Tuesday. (FYI) Next class – 10 th Grade Pre-test for Chemistry (it doesn’t count for a grade). The Chemistry teachers want to know how much you know about Chemistry before taking our course so that we may know what areas to focus on.

5.  Element: any material that cannot be broken down by chemical means.  Physical Property: a property that can be measured without causing a change in the substance’s chemical composition  Chemical Property: a characteristic that a substance undergoes in a chemical reaction that produces new substances  Luster (shiny): the reflection of light from the surface of a material described by its quality and intensity  Ductility: a property that describes how easy it is to pull a substance into a new permanent shape, such as, pulling into wires.  Malleability: the ability to be hammered into a shape without breaking.  Reactivity: a property that describes how readily a material will react with other materials.
