Question #6

The two graduated cylinders pictured can hold the same amount of water and use the same scale. A student measures the masses of two metal balls. One ball is made of aluminum and the other ball is made of lead. The student adds 50 mL of water to each graduated cylinder and then drops one metal ball into each graduated cylinder.

(See Picture)

In repeating the investigation, the student accidentally drops and steps on the lead ball. This action changes its shape from a sphere to an egg-shaped solid. The lead ball is placed back into the graduated cylinder.

In your Answer Document, predict what effect, if any, this change has on the amount of water displaced by the lead ball. Explain your prediction.

Predict
Once placed in the graduated cylinder, the egg-shaped ball will displace the same amount of water. / Explain
This is because the egg-shaped ball will have the same volume as the original ball(the ball was only changed physically.)

Question #16

Students do an investigation on the reaction of baking soda with vinegar. They create a data table to record the mass (grams) and temperature (degrees Celsius) of the mixture every 5 seconds. Several pieces of data are missing from the table.

In your Answer Document, give one example of how the incomplete data make it difficult for the students to draw conclusions about the changes that occur when baking soda reacts with vinegar.

Explainhow the incomplete data will affect the ability of other students to reproduce the experiment.

Explainhow the incomplete data will affect the ability of other students to reproduce the experiment.

(2 pts.)

One Difficulty of incomplete data
The students would be unable to draw conclusions about the change in the mass that occurs because they did not record the beginning mass of the mixture. / Explain one affect for reproducing experiment
Students who try to replicate the experiment will have a difficult time because they have an incomplete data table to compare their data.

(4 pts.)

Support
Fossil Fuels:
(coal, natural gas, oil, other petroleum fuels)
  • abundance/availability (if locally abundant it would cut down on transportation costs)
  • Provide Jobs: coal mining
  • Cost: less expensive if locally abundant
Renewable Resources:
(hydroelectric, wind, solar, geothermal)
  • Availability: rivers and dams
  • Renewable
/ Support
Nuclear:
  • Less air pollution
  • Large amounts of uranium avail.
  • Use small amounts of uranium to produce lots of energy.
  • Uranium supply will last a very long time.

Against
Fossil Fuels:
(coal, natural gas, oil, other petroleum fuels)
  • Nonrenewable
  • Air pollution
  • Global warming: burning fossil fuels produces carbon dioxide which is a greenhouse gas.
Renewable Resources:
(hydroelectric, wind, solar, geothermal)
  • Cost: technology associated with these types of resources is costly
Availability: (falling water, geothermal heat) not always readily accessible / Against
Nuclear:
  • Safety: Although small, potential exists for radioactive contamination
  • Disposal of waste: Although only small amounts of waste are produced, they are radioactive, which presents a disposal issue.
