If the temperature of a substance is lowered, what will happen to the molecules in the container?  (Will the molecules move closer together, will the molecules move farther apart, or will the molecules remain the same?)

               glass A                    glass b

Glass A is 90 ^oC.                        Glass B is 30 ^oC.

What will happen to the water in each glass if they are poured into water that is 60 ^oC? (Will the water from glass A rise or sink?  Will the water from glass B rise or sink?)

Where would you find the lowest levels of salinity in the ocean? 

a. in the Gulf Stream

b. on the ocean floor

c. near a river mouth

d. in the middle of the ocean

 

This is a drawing of a river flowing into an ocean.  What conclusion can you make about the salinity of the ocean near the river?  (Will the salinity of the ocean near the river increase, decrease, or remain the same?)

 

Why can you conclude this?

Amount of Salt

This table shows the amount of salt that students added to four beakers--all with equal amounts of water. Which beaker can you conclude has denser water than all of the other beakers?

What would you use to measure the amount of water that had been absorbed by a sponge? A thermometer, a balance, a graduated cylinder, or a ruler?

Deep ocean currents are caused by changes in temperature.  What will happen as the temperature of the water decreases? (Will the water sink, rise, or evaporate?)

Come up to the board and show where the Gulf Stream is located.

Which of the following is true about the number of organisms living in the ocean?

b. As the depth decreases, the number of organisms decreases.

c. As the depth increases, the number of organisms remains constant.

d. As the depth increases, the number of organisms increases.

This chart shows different attributes of ocean water movement.  Label each Column (A, B, C, & D) with the appropriate titles (tsunamis, waves, surface currents, tides).

Based on this food web, which organism is a producer?

What do a scallop, a dolphin, a sea urchin, and a crab all have in common?

a. They swim in the surface currents.

b. They float in deep ocean currents.

c. They dig on the ocean floor.

d. They live in fresh water.

e. They live in the ocean.

The effect of temperature on organisms

  ----------------------------------->

What conclusion can me made by using the diagram above?

a. As the water reaches a moderate temperature, the amount of organisms found in the water increases.

b. As the water reaches a moderate temperature, the amount of organisms found in the water decreases.

c. As the water reaches a high temperature, the amount of organisms found in the water increases.

d. As the water reaches a low temperature, the amount of organisms found in the water increases.

a. sand and water

b. sports drink powder and water

c. sugar and water

d. iced tea powder and water

This chart shows symbols for common elements.

This is a model for Carbon Dioxide (ignore the letters insice the circles.)

Use the chart to determine what elements make up a Carbon Dioxide molecule.  (Which specific atoms, and how many of each)

In which zone would you find a marine organism with small eyes, a very large mouth, and light organs to attract prey? (sunlight, twilight, or midnight zone?)

If you travel from 8 to 7 in the diagram above, what conclusion can you make about the depth, temperature, and marine life of the ocean? (Will the depth increase or decrease?  Will the temperature increase or decrease?  will the marine life increase or decrease?)

PART 1:

Scientists studied the number of animals at different depths in the ocean. They found the following results: There were 1000 organisms between 0-200meters. There were 500 organisms between 200-500 meters. There were 100 organisms between 500-5,000 meters. There were 50 organisms deeper than 5,000 meters.

What was the independent (manipulated) variable in this study?

a. the type of organisms

b. the depth of the water

c. the temperature of the water

d. the number or organisms

PART 2:

Jordan wants to see if adding different substances to water changes the time needed to boil the water.  He added ten grams of sugar to the first beaker, ten grams of salt to the second beaker, and kept pure water in the last beaker.  He heated the three beakers shown below on a hot plate until the liquids boiled.

Which of the following is the dependent variable?

a. mass of sugar added to the water

b. mass of salt added to the water

c. the time it takes for the contents to boil

d. the shape of the beakers
