Part B: In part C, you will cover the mixing bowl with plastic wrap and put the ice cubes on the top of plastic. What do you think will happen to the water in the bowl? Write down your hypothesis. Part C
Now conduct the experiment. Tightly secure the plastic wrap around the top of the mixing bowl over the hot water. Place the ice cubes on top of the plastic wrap above the cup. For the next 10 to 15 minutes, record the changes that occur on the plastic wrap and inside the bowl. Then remove the plastic wrap and look inside the cup. Write down your observations.

Analyze and Extend
Answer the following questions about your model.

Part A
Was your hypothesis correct? Why or why not?

Part B
Why was it important to heat the water for this experiment? What heats the water in the oceans, lakes, and rivers found on Earth?

one would be wind another would be water density

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.

the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.
