9.6.11 Physical Properties OBJ: We will create a word wall to further our understanding of scientific vocabulary. • TEK 6.6A • Warm up: Draw and label the measurements with the correct units for science! cm cm cm
Luster • The way it reflects light; shiny or dull
Ductile • Can be drawn into wire
Brittleness • How easily it breaks
Malleability • How well it can be hammered into sheets
Magnetism • Attracted or not attracted to a magnet
Conductivity • How well it allows electricity to move through
Recall: Physical properties is anything you can observe using your senses. • Summary: Which word was your favorite? Why? • Out: Half page reflection on what you learned and what you did during this class period.
9.7.11 Elements • We will be able to describe properties of elements by taking notes and making observations • Warm up: Draw the picture and finish the sentence This is a __________, it measures ___________ in units of ___________.
Examples & Non-examples What’s the Pattern?
Example Non-example
Non-example Example
Non-example Example
Non-example Example
Non-example Example
Non-example Example Your turn to create an “Example.”
Non-example Example Element: An element is a pure substance that is composed of the same type of matter throughout and cannot be divided into simpler substances through normal processes
Why do “examples” represent elements while the “non-examples” don’t?
Recall: Write your own definition of what an element is. • Summary: What did you do today to be successful? • Out: Half page reflection on what you learned and what you did during this class period.
9.8.11 Metals and Non-metals • OBJ: We will conduct and investigation to determine physical properties of various elements. • WARM up: list all the physical properties of tin foil
SAFETY Only use the tools for what they are intended for! Remember and foul play and you will receive a zero for this lab! • Flashlight- do not shine in anyone’s eyes • Do not put anything in your mouth! • Do not drop or crush any item • Do no touch anyone with your tools or items • Leave materials in the petri dish while conducting your tests
Station A – Carbon Record all findings on the Metals and Nonmetals Student Data Table. Materials: • carbon • magnet • flashlight • conductivity tester Procedure: • 1. Test the carbon sample with the flashlight to test for luster. • 2. Test the carbon sample with the magnet to test for magnetic attraction. • 3. Test the carbon sample with the conductivity tester to test for its ability to • conduct a current. Example
9.9.11 Metals and Non-metals (2) • OBJ: We will conduct and investigation to determine physical properties of various elements. • Warm up: Draw and complete the sentence This is a ________ it measures, __________ in units of _________
METALS usually… • Are silver-grey in color • Are solids at room temperature (except for Mercury) • Reflect light when polished (luster) • Can be bent or hammered flat (malleable) • Can be drawn into wire (ductile) • Are strong and resist bending and breaking (tensile strength) • Have a characteristic sound when struck with an object (sonorous) • Have high melting points • Have high boiling points • Are good conductors of heat and electricity • Have high densities (heavy for their size) • Are attracted to a magnet
NONMETALS usually… • Exist as solids, liquids, or gases at room temperature • Do not reflect light well (no luster) • Are brittle • Cannot be hammered flat (not malleable) • Cannot be drawn into wire (not ductile) • Are soft and bend or break easily (low tensile strength) • Don’t have a characteristic sound when struck with an object (not sonorous) • Have low melting points • Have low boiling points • Are poor conductors of heat and electricity • Have low densities (light for their size) • Are not attracted to a magnet
Complete PART 2 on the chart! • Were all the materials you tested easy to separate into metals or non-metals? • What properties helped you to separate the materials? • Did all metals give the same results? • Which metals did you find not to be attracted to a magnet? • Which metals did not have luster? • Why don’t all the metals behave the same way?
Recall: Describe what a metal would look like. • Summary: What did you do today to be successful? • Out: Half page reflection on what you learned and what you did during this class period.
