4Warm-up 9/6/11 What is Matter? List 10 things that are matter. What is mass?What is volume?
5What is the formula for density? Do you know the formula triangle? Essential Questions: What is intensive and extensive properties? Look in bookWarm-up 9/6/11What is the formula for density?Do you know the formula triangle?What are mass and volume?D = m/v
6What is the formula for calculating volume of cylinder? Pre-labWhat is the formula for calculating volume of cylinder?How do we calculate the volume of irregularly shaped object?V= r2hWater displacement Eureka!!!
7Density Lab 9/6/11 What is each cylinder made of? 4 different types of cylinderuse formula for cylinder to calculate volume of silver and golduse water displacement to calculate volume of black and white plasticmeasure mass of all on balance
8Essential Questions: What is intensive and extensive properties Essential Questions: What is intensive and extensive properties? Look in bookWarm-up 9/7/11Examples of intensive-Examples of extensive-Tiz tomorrow
9Unit Essential Question: What is density Unit Essential Question: What is density? Daily EQ: Can we graph density?Warm-up 9/6/11The slope of the mass vs. volume graph is equal to what?When graphing mass vs. volume who is on what axis?Quiz Today – Yeah!!
10Density ProblemsIf 25.6 grams of a substance has a volume of 5.7 mL, what is the substance? How do I know how to round it off?What mass of aluminum occupies 18.98cm3 ?25.6 g = = 4.5 to sig figs5.7mLUse yellow packet find density of aluminumD = m/v2.702g/ml = m/18.98cm3m = grams
11Penny Lab 1) Select 10 Pre-82 pennies and 10 ‘83 and newer 2) Determine the density of each set of pennies.You can use either method to determine volume.3) Find the metal on page R-47 through R-49Make sure it sounds like a reasonable metal4) What other physical or chemical properties could we use to make the final distinction
12Essential Question: What are chemical vs physical properties? Warm-up 9/15/09What are physical and chemical changes?To doQuiz Thursday (some warm-ups)
13Unit Essential Question: What is density Unit Essential Question: What is density? Daily EQ: Can we graph density?Warm-up 9/16/091) What is the density of 78 grams of aluminum that has a volume of 28.87mL?2) How many grams of gold were found in the ship wreck if it occupied 435cm3 of space (density of gold is g/cm3) ?Quiz tomorrow
14Unit Essential Topic: Physical vs Chemical changes, The battle wages on ! Warm-up 9/7/11Daily EQ: What three things indicate that you have had a chemical change/reaction?What is Find and Fix?Quiz returned – figure out which ones you got wrong and find correct errors
