Presentation on theme: "Do Now Let’s Brainstorm! Compare these two objects:"— Presentation transcript:

1 Do Now Let’s Brainstorm! Compare these two objects:
Which one of them has a greater mass? Defend your argument Which one of them has a greater volume? If you put these items in water, which will sink? Which will float? 1 kilogram of feathers 1 kilogram of rocks

2 You are successful if… You can write your own definition of “density”
You can solve basic density calculations You can solve the “Density Problems” at the bottom of your guided notes

3 Density = amount of matter per unit volume
Density is the ratio of mass to volume Density = mass volume Mass is measured in grams Volume is measured in mL or cm3 Therefore… it is measured in grams milliliters

4 Which one is more dense? Demonstration: People in a square
How about this: Which square is more dense?

5 Which one is more dense? Now which one is more dense?

6 “Compactness” Hot air balloon - Describe how a hot air balloon works. Defend your argument.

7 The “DMV” Triangle for Volume, Mass, and Density
÷ D X V Density = M V Volume = M D Mass = D x V

8 If the volume stays the same and the mass increases
If the volume stays the same and the mass increases the density will increase If the mass stays the same and the volume increases The density will decrease

9 Let’s solve an example problem…
Ms. Locke has a block of chocolate. It has a mass of 50 grams, and has a volume of 10 cm3. What is the density? Identify the variable you are solving for. Isolate the variable to one side of the equation. Plug and chug! Make sure you have the correct units. Never leave naked numbers  Yup! We are looking for this one Density = Mass Volume Density = 50 grams 10 cm3 Density = 5 g/cm3

10 What if we have to solve for mass or volume???
Ms. Locke makes popsicles, using lemonade mix and water. Each popsicle has a density of 0.5 grams/mL. She used 100 mL of water. How many grams of lemonade mix did she use to make the popsicles? What is the mass? Identify the variable you are solving for. MASS Isolate the variable to one side of the equation. Plug and chug! Make sure you have the correct units. Never leave naked numbers  Density = Mass Volume (Volume) (Volume) (Density) = Mass (100 mL)(0.5 grams/mL) = 50 g

11 Independent Practice Work quietly
I don’t mind if you ask a neighbor for help But we are at Volume 1, NOT a Volume 2 If you don’t finish in class, finish it for lifework 
