  1. . Warmup: “I predict ” “A golf ball dropped in water will (float? sink?)” “This apple dropped in water will (float? sink?)” “A rock dropped in water will (float? sink?)” Purpose: How can we predict what will float in what? Today Density in the computer lab Friday Test #1 (closed notes)

  2. HOW TO STUDY FOR FRIDAY’S TEST • Re-do your worksheets. • Look at your Quiz #1 questions again. • Understand your movie notes. For Friday’s Test (closed notes) Know how these words relate to what we learned: Latitude, Longitude, Prime Meridian, Equator, Cartographer, Parallels, Meridians, degrees, minutes, seconds, density, mass, volume, stromatolite, pillow lava, ultraviolet light, ozone layer, radioactive materials, Burgess Shale fossils

  3. Today’s notes: To predict whether something will float in something else, we need the “density” of that thing. Soy Oil density = 0.926* Water density = 1.00* g/mL We predict that water will (float/sink) in soy oil because water’s density is (greater/less than) soy oil. * This measurment is in grams per milliliter.

  4. Today’s notes: To measure density, we first need to know the volume of an object. Volume can be measured by writing down TWO numbers. Water level before dunking the object And water level after dunking the object. The volume of this rock must be…

  5. Today’s notes: Memorize this formula by Friday: If a golf ball mass is 40 grams And the golf ball volume is 20 mL, what is the density of the golf ball?

  6. In the computer lab, finish both sides of the sheet by the bell. Today’s sheet is worth 5 points
