1/4/12 A/B DayLEQ: How can we use physical propertiesto identify different substances?1. What does the word “malleable” mean?2. Which elements do we consider malleable:metals, nonmetals, or metalloids?3. Is aluminum malleable?4. A scientist wants to do an experiment and heneeds something that is a conductor. Should hepick a metal, a nonmetal, or a metalloid?5. Explain your answer to number 4!!!
AGENDA:1. Quick Chemistry Review2. Lecture (Notes, Videos, and Demos)3. Practice today’s material4. Summarizer5. Finish Review Stations
Lets Review: WRITE THIS IN YOUR NOTES!1. MALLEABLE:2. DUCTILE:3. CONDUCTOR:4. INSULATOR:5. MAGNETIC:

Today’s LEQ: How can we use physical properties to identify different substances?By the end of today, you should be able to…1. Explain the difference between a boiling point and melting point specific heat, and solubility2. Define specific heat3. Define solubility4. Identify substances with these properties
FOCUS VOCABULARY75. Boiling Point76. Melting Point77. Specific Heat
SPECIFIC HEAT: amount ofheat needed to raise 1gram of something by 1degreeEx: Low S.H. = easy to heat High S.H. = hard to heat
VIDEO: SPECIFIC HEATSpecific Heat capacity(Discovery Ed)
Specific Heat Chart: HIGH SPECIFIC HEAT: Hard to heat up (takes a lot of heat to get hot!) LOW SPECIFIC HEAT: Easy to heat up! (Doesn’t take a lot of heat to get hot!)
Specific Heat Chart: IN YOUR NOTEBOOK… LIST these elements from EASIEST to heat to HARDEST to heat!
LETS PRACTICE!!! Use the chart provided to answer questions 1-20 in your notebook.(Complete sentences NOT required) Let’s check our answers…
SUMMARIZER:1. What is the difference between a boiling point and a melting point?2. What is specific heat?3. How can we use boiling points, melting points, and specific heat to identify different substances?
