This baby is bigger than it looks – 30lbs!

I even made a turkey from veggies! If there was a Thanksgiving version of Chopped, I would’ve ruled BIG TIME. Everything came out beautifully, and I’m so thankful for good friends that brought this all together with me.

1. Describe the movement of the atoms or molecules in a gas.
2. A liquid takes the shape of its container, but why doesn’t a liquid expand to fill the container completely?
3. When you push down on a confined fluid, you create pressure. In what direction does the pressure act?
4. What happens to the temperature of ice at its melting point while you add heat? While it is melting, does it gain or lose energy?
5. What is evaporation? How is it different from boiling?
6. You place 1 liter of a substance into a 2-liter bottle and tightly cover the bottle. The substance expands until it completely fills the bottle. What state is the substance in?
7. Describe how the density of ice affects our daily lives. Explain why ice forms on the top of ponds and lakes, and not the bottom. Use the following terms in your explanation: density, organized structure, and water molecules. How does this property of water help support life in lakes and ponds?
8. Why doesn’t convection occur in a solid material?
9. Why is it more comfortable to exercise on a day when the relative humidity is low?
10. Convection creates circulating currents in a pot of boiling water because ____ water rises and ____ water sinks.

These skulls were made from salt dough and painted by my art class.

Artist Momoko came to teach us her technique of line scaping. These are the pieces that my students created.

Mini-poster assignment:

• Draw the outline (like a coloring book picture) of a solid, a liquid, and a gas

• Label the objects –  solid, liquid and gas

• Fill in the objects with circles that represent how the molecules behave in each state (just like we drew in our notebooks for class notes)

  Earn 6 points toward a low lab or homework score; 1 point for each drawing with correct molecule depiction, and 1 point for each label.

Here’s an outline of what you need to study:

I. Calculating mass, volume and density

a. use the dmv triangle to determine which equation to use

b. plug in the known values

c. solve the equation with proper units of measure (mass in grams, volume in cm3 or mL, and density in g/mL or g/cm3)

II. Definitions

a. mass

b. density

c. volume

d. meniscus

e. Archimede’s Principle

III. Density of water

a. will and item sink or float based on mass and volume

IV. Buoyancy

a. definition

b. positive, neutral and negative buoyancy (what that looks like for a submarine or for a hot air balloon)

V.  Determining the volume of objects

a. By weighing on a digital or triple beam balance (liquids in container)

b. By displacement of water (solid objects)

VI. From Last Exam

a. Steps of the scientific method

b. Lab equipment

c. metric prefixes

Oh, I need to do this in my class next time I teach density!
