4 Warm-up 9/6/11 What is Matter? List 10 things that are matter. What is mass?What is volume?
5 What 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
6 What 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!!!
7 Density 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
8 Essential 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
9 Unit 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!!
10 Density 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
11 Penny 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
12 Essential Question: What are chemical vs physical properties? Warm-up 9/15/09What are physical and chemical changes?To doQuiz Thursday (some warm-ups)
13 Unit 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
14 Unit 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
