Density+Activities


 * Density Activities **
 * __Day 1 Objectives: __**
 * 1) To understand how temperature affect molecules
 * 2) To understand how temperature can change density.
 * 3) To understand the temperature of the ocean and how the temperature of the ocean can change.

**Gas properties**-temperatures affect. __Scenario #1 __ Follow the directions below: media type="custom" key="29397365" align="center"
 * 1) Go to the PhET website (below) and run the “Gas Properties” simulation.
 * 2) Once the simulation is running, make volume your constant parameter, and add 50 heavy species to the container.
 * 3) Add heat several times and observe what happens to the molecules.

Answer the following questions in you notes according to what you see happen when you change the parameters in the Phet simulation:
 * 1) When you heat the gas, what happens to the average speed of the gas particles?
 * 2) What happens to the frequency with which they hit the sides of the container?
 * 3) What do you think the molecules would do if they weren't confined to the container? Explain.
 * 4) Complete the following statement: “When the temperature of molecules **__(BLANK)__**, the speed that the molecules move //**__(BLANK).__**//

__Scenario #2 __. Follow the directions below:
 * 1) Reset the simulation and again make volume your constant parameter.
 * 2) Add another 50 heavy species to the container
 * 3) Remove heat (add ice) several times and observe what happens to the molecules.

Answer the following questions in you notes according to what you see happen when you change the parameters in the Phet simulation:
 * 1) When you remove heat from the gas, what happens to the average speed of the gas particles?
 * 2) What happens to the frequency with which they hit the sides of the container?
 * 3) What do you think the molecules would do if they weren't confined to the container? Explain.
 * 4) Complete the following statement: “When the temperature of molecules **__(BLANK)__**, the speed that the molecules move //**__(BLANK).__**//


 * __Day 2 Objectives: __**
 * 1) To understand how density affects molecules.
 * 2) To understand how density can change based on other forces.
 * 3) To understand the temperature of the ocean and how the temperature of the ocean can change.

**Density 1.05**- sinking vs. floating Follow the directions below: Create the table below in your notebook but make the boxes big enough for you to record 3 things: **In box in your chart should list the #'s 1,2 and 3.** media type="custom" key="20843738"
 * 1) A description of how the boxes are different, Talk about size/volume and mass)
 * 2) A prediction of what you think will happen when you put it in the water
 * 3) What you see happen when you put the box in the water
